Precautions for the maintenance of electric bike lithium batteries

Lithium batteries can easily enter the electric vehicle market with the advantages of compactness, light weight and environmental protection. Heavy, short-lived, and heavily polluting lead-acid batteries can no longer meet our needs. The lithium battery is cured and can be used for 5-7 years. Good car use habits are of great help to extend the battery life of electric vehicles.

So, what are the precautions for lithium battery maintenance?

Lithium battery charge and discharge maintenance

New lithium batteries are all aging, you don't need to charge them when you get new batteries, you can use them directly.

Lithium batteries have no memory effect, they can be charged with shallow charging and charging when used. If you wait for the battery to run out of power before charging, it will shorten the life of the lithium battery. Even if you can exercise for 2-3 days on a single charge, it is recommended that you charge it every day. Keep the battery in a shallow cycle state, which is conducive to extending the battery life.

A regular deep discharge of lithium batteries is also conducive to "activating" the battery, which can slightly increase the capacity of the lithium battery. The general method is to fully discharge the battery periodically. The method of full discharge is to ride the bike to the first undervoltage protection under normal load conditions on a flat road. Note that we especially emphasize the first undervoltage protection. After the battery is under voltage protection for the first time, after a period of time, the voltage of the battery will rise and return to a non-undervoltage state. At this time, if the battery is used again, the battery will be seriously damaged. After the complete discharge, the battery is fully charged. You will feel the battery capacity has improved.

The best charging environment for lithium batteries is 20~26℃, try to avoid charging at high temperature outdoors at noon in summer and charging outdoors at night in winter. Too high temperature is easy to overcharge, and too low temperature is easy to undervoltage, which will have a bad effect on the performance of lithium batteries.

Do not mix chargers randomly. The lithium battery must use the original lithium battery charger. Mismatched chargers can easily cause battery short circuit, high heat and even explosion. The charger should pay attention to ventilation when charging, otherwise it will not only affect the life of the charger, but also may cause thermal drift and affect the battery life.

Good riding habits

1. Good riding habits not only maintain the car but also protect the battery. The habit of kicking the ground with your feet at the beginning is good for electric vehicles. Relying on external forces to start the car will reduce battery pressure and extend the life of the lithium battery.

2. Do not remove the speed limit of the electric vehicle controller. This is not safe, it will also reduce the efficiency of lithium batteries and reduce battery life.

3. When encountering a climbing section, pedal assist, try to avoid instant large current discharge. This will not only affect the mileage of the lithium battery, but the continuous high-current discharge will also affect the performance of the lithium battery. The same is true for load.

4. Use taxi as much as possible. When going downhill, take advantage of the advance power off and coast down as much as possible. When you are about to encounter a traffic light, enter the taxi early to minimize braking.

Precautions for Lithium Battery

It is particularly reminded that when the battery is in the northern winter and enters a warm room at a low outdoor temperature, frost and condensation will appear on the surface of the battery. In order to avoid battery leakage caused by frost and condensation, the battery should be charged after the battery temperature rises to close to the indoor temperature and is dry.
