For a long time, the durability of electric vehicle batteries has been a key topic for users. Many users have this question, which is how to make the vehicle run more than ten kilometers? Actually, in my opinion, only these four points need to be achieved to maximize the vehicle's range.

1. Try to control the remaining battery level to 30% to 50% for charging, and do not use it all up

Firstly, the first point is not to recharge the vehicle's battery every time you ride, as doing so for a long time can damage the battery and affect its durability. The correct approach is to try to control the remaining battery power to 30% to 50% for charging, which is more conducive to protecting the battery and extending its service life.

2. Try to maintain low-speed driving as much as possible

Secondly, for electric vehicles, many vehicles have three gears, and although the low gear is slower, it runs the most energy-efficient and has the longest range.

3. Maintain reasonable tire pressure

In addition, tire pressure can also affect the vehicle's range. For ordinary vehicles, if the tire pressure is insufficient, the resistance during driving will increase and the range will be shortened. Therefore, maintaining a reasonable tire pressure can minimize driving resistance and ensure a longer range of the vehicle.

4. Do not mix inferior chargers for charging

Finally, it is important not to mix chargers for charging, as mixing inferior chargers not only poses safety risks, but also results in insufficient or insufficient charging, and in severe cases, may even damage the battery. Therefore, not mixing inferior chargers for charging, and using dedicated chargers for vehicles, is beneficial for protecting the battery and extending its range.

In short, electric vehicle batteries are not durable. Under normal and fault free conditions, the above four methods can be tried. Generally speaking, they are beneficial for extending the range of electric vehicles, and it is also possible to run more than ten kilometers. However, it should be noted that choosing high-quality batteries is also necessary.

Low-speed vehicles (LSVs), whether used for personal transport, short-distance travel, or golf carts, are becoming increasingly popular. These vehicles rely heavily on battery life, particularly lithium-ion batteries, for their energy storage needs. Proper maintenance and care are essential to ensure the longevity and efficiency of these batteries. In this blog, we will discuss tips on how to maintain and extend the life of your low-speed vehicle battery.

1. Charge Regularly, But Don't Overcharge

Regular charging is key to keeping your low-speed vehicle battery in good condition. However, overcharging can damage the battery and shorten its lifespan. Always follow the manufacturer’s recommended charging guidelines, and avoid charging beyond the full charge mark.

For lithium-ion batteries, it’s also a good idea to avoid draining the battery completely before recharging. Try to recharge it when it reaches around 20-30% to ensure optimal performance.

2. Store Your Battery in a Cool, Dry Place

Temperature extremes—both hot and cold—can adversely affect the battery’s performance. Excessive heat can cause the battery to degrade faster, while cold temperatures can reduce its efficiency. Store your low-speed vehicle in a cool, dry place, ideally between 50°F and 77°F (10°C to 25°C), when not in use for extended periods.

3. Use Your Low-Speed Vehicle Regularly

If you use your low-speed vehicle infrequently, the battery may lose charge over time. Even when you're not using it, it’s a good idea to drive the vehicle once every couple of weeks to keep the battery active and in top condition.

Additionally, leaving the vehicle unused for too long can lead to issues like sulfation (in lead-acid batteries) or a decrease in capacity, which can significantly reduce the battery’s performance.

4. Avoid Deep Discharge

Deep discharges can reduce the lifespan of your battery significantly. It’s best to recharge your battery before it drops too low in charge. Many low-speed vehicles feature battery level indicators to help you track charge levels, making it easier to avoid complete depletion.

5. Maintain Proper Tire Pressure and Vehicle Load

Maintaining optimal tire pressure and ensuring your low-speed vehicle is not overloaded will reduce stress on the battery. This means your vehicle will require less energy to operate, helping extend the battery’s life. Check tire pressure regularly and ensure the load is within the recommended limits.

6. Regularly Clean Battery Terminals

Clean battery terminals and connectors are essential for smooth battery operation. Dirt, grime, and corrosion can build up on the terminals, reducing the efficiency of the battery and causing it to work harder than necessary. Periodically inspect and clean the terminals using a soft brush and mild cleaning solution to ensure they remain free of debris.

7. Monitor Battery Voltage and Performance

If your battery starts to show signs of reduced performance, such as a decrease in driving range or slower charging times, it may be time for maintenance or replacement. Regularly monitor the battery’s voltage and performance to ensure it’s operating within the recommended parameters.

8. Avoid Exposure to Direct Sunlight

When parking your low-speed vehicle outdoors, avoid leaving it in direct sunlight for extended periods. The sun’s heat can cause the battery to overheat, potentially leading to damage. Parking in a shaded area or using a cover will protect both your vehicle and battery from the harmful effects of prolonged exposure to the sun.

The research and development of lithium batteries can be traced back to the 1970s. Early lithium batteries used materials such as lithium cobalt oxide as the positive electrode.

With the continuous advancement of technology, the types of lithium batteries have gradually increased. Lithium iron phosphate batteries were developed in later research. They have unique advantages in safety and cycle life, and have gradually become an important part of the new energy field.

1. The Difference In Chemical Composition and Principle

Lithium batteries generally use lithium metal or lithium alloy as the negative electrode material, and there are many types of positive electrode materials, such as lithium cobalt oxide (LiCoO₂), lithium manganese oxide (LiMn₂O₄), etc. Taking lithium cobalt oxide batteries as an example, during the charging and discharging process, lithium ions are intercalated and deintercalated between the positive and negative electrodes. When charging, lithium ions are removed from the positive electrode and embedded in the negative electrode through the electrolyte; the opposite is true when discharging.

The positive electrode material of lithium iron phosphate battery is lithium iron phosphate (LiFePO₄), and the negative electrode is usually graphite. During the charging and discharging process, lithium ions also move between the positive and negative electrodes. The crystal structure of lithium iron phosphate is stable, which makes the battery have good safety and stability during the charging and discharging process.

2. Energy Density Difference

Lithium battery: The energy density is relatively high. For example, the energy density of lithium cobalt oxide battery can reach about 150-200Wh/kg. This makes lithium batteries widely used in some electronic devices with high volume and weight requirements, such as smartphones, laptops, etc., and can provide devices with longer battery life.

Lithium iron phosphate battery: The energy density is generally between 100-150Wh/kg. Although the energy density is relatively low, in some application scenarios where the energy density requirements are not particularly extreme, such as electric buses, energy storage power stations, etc., its safety and cycle life are more prominent.

3. Safety Differences

Lithium battery: Some lithium batteries, such as lithium cobalt oxide batteries, may have safety problems such as thermal runaway under conditions of overcharging and high temperature. Because lithium cobalt oxide is structurally unstable at high temperatures, it is easy to release oxygen, which can cause dangerous situations such as combustion.

Lithium iron phosphate battery: It has excellent safety. It has good thermal stability and is not easy to decompose under high temperature conditions. The crystal structure of lithium iron phosphate can effectively prevent the disordered migration of lithium ions and reduce the risk of internal short circuits in the battery. Even in extreme cases, such as puncture and extrusion, lithium iron phosphate batteries are relatively unlikely to have serious accidents such as fire and explosion.

4. Cycle Life Difference

Lithium battery: The cycle life is generally around 500-1000 times, depending on the type of battery and the conditions of use. As the number of cycles increases, the battery capacity will gradually decay, affecting its performance.

Lithium iron phosphate battery: The cycle life is relatively long, reaching more than 2000 times or even higher. This makes it have great advantages in application scenarios that require long-term frequent charging and discharging, such as energy storage systems, which can reduce the frequency of battery replacement and reduce overall costs.

5. Charge and Discharge Performance

Lithium battery: The charging speed is relatively fast, and some lithium batteries can be fully charged in a shorter time. However, charging too quickly may have a certain impact on the battery life. In terms of discharge performance, it can meet the needs of most electronic devices and provide a relatively stable current output.

Lithium iron phosphate battery: The charging speed is relatively slow, which is one of its current shortcomings. However, in terms of discharge performance, lithium iron phosphate batteries have better large current discharge capabilities and are suitable for some applications that require instantaneous high power output, such as acceleration of electric vehicles.

6. Differences in Application

Lithium batteries are widely used in consumer electronics due to their high energy density and light weight, such as mobile phones, tablet computers, laptops, etc. At the same time, they are also used in some electric vehicles that require higher energy density, such as some of Tesla's early models that use lithium cobalt oxide batteries.

Lithium iron phosphate batteries are widely used in the field of new energy vehicles, especially in commercial vehicles such as electric buses and logistics vehicles. Their safety and long cycle life can meet the operational needs of commercial vehicles. In addition, they have also been widely used in energy storage fields such as energy storage power stations and solar street lights, providing a reliable solution for energy storage and utilization.

After a careful comparison between the two, there are obvious differences between lithium iron phosphate batteries and lithium batteries in terms of chemical composition, performance characteristics and application areas. They each have their own advantages and disadvantages, and play an important role in different scenarios.

With the aging population and increasing demand for accessibility, stairlifts are becoming more common in homes and public buildings. As one of the key components of stair lifts, the performance and maintenance of stairlift lead-acid batteries directly affect the reliability and lifespan of the equipment.

1. Battery Power Needs and Operation in Stairlifts

Modern stairlifts are powered by lead-acid batteries, usually installed in the cabin (where the motor is located), which help move the lift up and down the stairs. The batteries are charged by connecting to charging points, and the charger provides low-voltage trickle charging from the main power supply to keep the batteries charged.

2. Battery Lifespan and Maintenance

The lifespan of lead-acid batteries typically ranges from 3 to 5 years, depending on usage and maintenance. It is recommended to perform an annual maintenance check to ensure the lift and batteries are working properly. Proper maintenance can extend battery life, so regular cleaning and checking of charging points and batteries is essential.

3. Common Problems and Solutions

If the battery isn’t charging, the issue may be caused by the following:

Power Supply Issue: Check if the main power outlet is on and ensure the power supply is working.

Charging Contact Issue: Make sure the stair lift is parked at the charging point. Check if the charging strip is clean and undamaged.

Charger or Circuit Issues: Verify that the charger and circuit are functioning properly. If needed, contact a professional for repairs.

Using the Lift During a Power Outage: If there is a power outage, the lift can still be used until the power is restored. However, to prolong battery life, limit the number of uses. A fully discharged battery won’t recharge and needs replacement. Uncharged batteries typically allow for about 8 trips up and down the stairs, depending on the model.

4. Battery Selection and Maintenance Tips

Stairlifts typically use battery 12V8Ah, 12V5Ah, 12V9Ah, 12V10Ah, or 12V12Ah lead-acid batteries. These batteries are safe, durable, and environmentally friendly. To prolong battery life, it’s recommended to have professional maintenance checks annually and regularly clean the charging strip to ensure good contact.

Lead-acid batteries, as one of the most mature electrochemical energy storage technologies, rely heavily on the quality of their battery plates. The manufacturing of battery plates integrates precision processes from metallurgy, chemistry, and materials science. This article delves into the full production process of green plates (unformed plates), from raw materials to final shaping, revealing the modern industrial wisdom behind this traditional technology.

I. Raw Material Preparation: Metallurgical Purification of High-Purity Lead

1. Lead Ingot Melting

We utilize electrolytic lead ingots with a purity of ≥99.99%, which are melted into liquid lead in a lead melting furnace at 450-500°C. To enhance mechanical strength, alloying elements are added in proportion:

Positive Plates: 0.3%-1.2% antimony (Sb) is added to enhance corrosion resistance;

Negative Plates: Lead-calcium alloy (0.08%-0.12% Ca) is used to reduce the risk of hydrogen evolution.

2. Lead Powder Preparation (Lead Oxide Generation)

Molten lead is atomized into micrometer-sized lead particles through a lead powder machine (using the Barton method or ball milling method). These particles react with air in an oxidation chamber to form porous lead oxide (PbO):

2Pb + O₂ → 2PbO

The lead powder has a particle size controlled at 2-5μm and a specific surface area of 0.8-1.5 m²/g, ensuring high reactivity for subsequent reactions.

II. Paste Preparation: The Core Carrier of Electrochemical Active Substances

1. Formula Mixing

Lead oxide powder, deionized water, sulfuric acid (density 1.40g/cm³), and fibrous additives (such as lignin) are mixed in proportion in a paste mixer:

Positive Plate Paste: Lead powder:Sulfuric acid:Water ≈ 100:8:12, forming a porous PbO·PbSO₄ framework;

Negative Plate Paste: Expanding agents (such as carbon black, barium sulfate) are added to inhibit passivation.

2. Paste Maturation

The mixed paste is left to mature in an environment at 35-45°C with humidity >90% for 8-12 hours, completing the following reaction:

4PbO + H₂SO₄ → 3PbO·PbSO₄·H₂O + H₂O

This forms a stable basic lead sulfate network structure, with the paste density reaching 4.0-4.3g/cm³.

III. Grid Manufacturing: The Mechanical Framework of Battery Plates

1. Alloy Casting

Using die-casting or continuous expanded mesh processes, lead-calcium/lead-antimony alloys are formed into grid-like structures:

Thickness: Positive plates 1.8-2.5mm, negative plates 1.2-1.8mm;

Grid Design: Diamond or radial patterns to reduce internal resistance and enhance active material adhesion.

2. Surface Treatment

The grids are cleaned with dilute sulfuric acid (5%) to remove oxide layers, forming a micro-rough surface to enhance paste adhesion.

IV. Coating and Curing: Precision Shaping of Active Materials

1. Automated Coating

Grids are evenly coated with paste using a double-belt coater, with precise paste application within ±0.5g per plate. The thickness is controlled by rolling (positive plates 2.5-3.0mm, negative plates 1.8-2.2mm).

2. Curing and Drying

The coated plates undergo a three-stage curing process in a humidity-controlled tunnel kiln:

Surface Drying (40°C, 2h): Rapid dehydration to prevent cracking;

Crystal Transformation (65°C, 12h): PbO·PbSO₄ → 4PbO·PbSO₄;

Final Drying (50°C, 6h): Residual moisture <0.5%.

This results in porous, high-mechanical-strength green plates (positive plates PbO/PbSO₄, negative plates sponge-like Pb).

V. Quality Control: Precision Manufacturing Empowered by Digitalization

Online Inspection: X-ray thickness gauges monitor paste uniformity in real-time;

Physical Indicators: Plate hardness (Shore A 50-65), bending strength (>15MPa);

Electrochemical Pre-testing: Random sampling for 0.5C discharge testing, with capacity deviation ≤3%.

VI. Environmental Protection and Innovation: The Industrial Revolution of Green Manufacturing

Lead Dust Control: Fully enclosed production lines with bag filters, lead emissions <0.1mg/m³;

Paste Recycling: Centrifugal separation technology achieves a paste reuse rate >95%;

Smart Factory: MES systems optimize process parameters at the millisecond level, reducing energy consumption by 18%.

The manufacturing process from lead ingots to green plates represents the perfect integration of materials science and engineering technology. Kaiying Power ensures that each battery plate combines high energy density with ultra-long cycle life through full-process digital control and green process innovation, providing a reliable power core for global energy storage systems.
