Reasonable charging time and method of lithium battery of electric vehicle

Lithium batteries are widely used in the simple models of electric bicycles, but what the differences between lithium batteries and lead-acid batteries? The correct pool charging method is the first time lithium battery charging and what needs to pay attention to it? Here's a typical scientific and technical.

Lithium electric vehicle battery is used correctly

The correct use of lithium batteries actually comes down to three points:

1. Lithium battery electric vehicle activation does not require a special method. The lithium battery will naturally activate during the electric vehicle driving. If you deliberately want to use the "first three 12-hour long charge activation" method, it will only be futile and have no effect.

2. When the lithium battery appears to be too low when the electric vehicle is running, the lithium battery should be charged as soon as possible. (There is no strong charging station here, it is super damaged battery. The saying that the battery is running out of recharging and the battery is charging for a long time is not all right, it depends on the type of battery, for "try to put the battery of the electric car as much as possible." When the power is used up, it is best to use it. It is only used on nickel batteries. The purpose is of course to avoid battery memory effects.) 3. Charge according to standard time and procedures, even in the first three times. Carry out; (especially don't do extra-long charging for more than 12 hours)

Lithium-ion electric vehicle battery incorrect use method

It is wrong to blindly pursue the 12-hour ultra-long charge and the use of lithium battery power to automatically lose power. If you have done it in the wrong way, please correct it in time.

Lithium battery daily maintenance and preservation

The lithium primary battery has a very low self-discharge, and can be stored for 3 years. It can be stored under refrigeration conditions, and the effect will be better. It is a good method to store the lithium primary battery in a low temperature place. Lithium-ion batteries can be stored for more than half a year at 20 ° C due to their low self-discharge rate and most of the capacity can be recovered. The self-discharge phenomenon of lithium batteries, if the battery voltage is stored for less than 3.6V for a long time, it will cause the battery to over-discharge and damage the internal structure of the battery, reducing battery life.

Therefore, the lithium battery stored for a long time should be recharged every 3 to 6 months, that is, the charging voltage is 3.8~3.9V (the optimal storage voltage of the lithium battery is about 3.85V), which is not suitable for filling. Lithium batteries have a wide application temperature range. They can still be used outdoors in the winter in the north, but the capacity will be much reduced. If you return to room temperature, the capacity can be restored and affected by a certain temperature. Unlike lithium-ion batteries, lithium primary batteries cannot be charged and charging is dangerous. Other precautions are equivalent to lithium-ion batteries.
