As the main source of electricity in new energy vehicles, batteries provide power support for various systems, and their quality directly affects the normal driving of the vehicle. So how do we measure the quality of the battery? We can judge from the following aspects:

   1. Appearance judgment

Observe whether the appearance is deformed, bulging, leaking, ruptured, scorched, scorched, and whether there is oxide seepage at the screw connection, etc.

  2. Battery testing equipment

The fastest inspection method is to test the internal resistance and discharge current. A good quality battery has very small internal resistance and a large discharge current.

Of course, there are also battery voltage drop (referring to the voltage difference when the battery is stored for a certain period of time in a static state), cycle life (referring to the number of times the battery is charged and discharged at a standard constant current and constant voltage), and battery platform time (referring to a certain cut-off voltage, The battery can discharge the total capacity of the amount of electricity), as well as resistance to high and low temperature discharge, large current overcurrent. To test the overall performance of a battery, a dedicated tester is necessary.
