How can we properly use lithium batteries in electric vehicles?

The correct way to use electric car lithium battery: 1, the timeliness of electric car lithium battery charge is every ride, do not run out of battery power, because the discharge of lithium battery is very harmful. Long-term overexposure can reduce the battery life by three times. At the very least, when there is a warning that the battery is too low, stop riding and charge the lithium battery. 2. The timeliness of lithium battery charging for electric vehicles is that lithium battery charging is effective at any time, even if there is 50% power before charging. This is because it is different from nickel metal battery, which has memory effect but lithium battery does not.

So far, except for nickel metal batteries, other lithium batteries have no memory effect and can be used and charged at any time. However, it should be noted that lithium batteries cannot be discharged excessively, which will cause irreversible capacity loss. Start charging as soon as the machine tells you it's low.

3, electric vehicle lithium battery to make up for self-discharge charging is if the battery is not used for a long time, the battery should be removed from the instrument and stored in a dry and cool place, and should be charged within 60~90 days, so as to avoid storage time is too long, the battery due to self-discharge lead to low power.

4. The original charging equipment of lithium battery for electric vehicles is to use the original lithium battery charger as far as possible. The original charger has strong supporting performance and moderate charging rate. Excessive current charging will also do great harm to the internal structure of the battery.

5, the temperature at which the electric lithium battery storage environment is polymer battery temperature environment with wider, for - 20 ℃ ~ 45 ℃, but in fact the most appropriate temperature is at room temperature. From the point of view of "aging", temperature may be the main reason for the gradual decline of lithium battery capacity.

Expand the data

When the lithium battery is idle, it should be placed in a cool and ventilated place to avoid high temperature and humidity. In rainy days, it should be avoided to ride. Even if riding, it should be protected to prevent the lithium battery from water. Do not knock, needle, trample, modify, insolation battery, do not place the battery in the microwave, high pressure environment.

The correct usage of lithium battery in electric vehicle is as follows:

1. The battery does not need to be "activated".

Lithium batteries do not require the first three charges more than 12 hours, lithium batteries have no memory.

2. Battery charging

Use the charger specified by the manufacturer. Pay attention to whether the charger model matches the battery model when charging.

3. Avoid charging at high temperature

Lithium-ion batteries do not charge under the environment of temperature more than 40 °, high temperature can make the battery capacity decline.

4. Timely charging

Lithium battery as far as possible with the implementation of the charge, avoid the battery every time under voltage after recharging, this can greatly improve the battery life. 5, store

When the battery is not used for a long time, the connection between the battery and the vehicle should be disconnected, and some power should be added to the battery at intervals, to avoid self-discharge of the battery, or the power consumption of the protection plate will put the battery away. Lithium batteries are more afraid of overcharge than over discharge. But lithium batteries have no memory effects and can be recharged as needed. Do not completely run out of electricity to charge, so easy to excessive discharge damage to the battery; Do not discharge large current, in steep places, it is best to use foot power, to avoid the battery current is too large, affect the battery life. In the same way, the loads specified in the specification should be avoided. Generally, the charger is fully protected and will not cause overcharging. However, in the middle of the night, the power grid load is very light and the voltage rises very high, so it is easy to exceed the full stop voltage set by the charger, and the battery will continue to be charged, which is easy to cause overcharging. In the middle of the night, the charger should be pulled out.
