In order to further examine the fault nature and extent of the battery, in order to perform the exact determination of its technical state, it can be inspected in conjunction with the battery charging process. According to the different manifestations of the battery, the internal failure of the traction battery and the cause of the traction battery are determined. .(1) Normal state. When charging the reference battery, the specific gravity of the battery voltage and the electrolyte is rising according to certain regulations, and the electrolyte temperature is not high. This indicates that the battery status of the battery is normal, but it is too much discharge, which should be charged.
(2) Vulcanization state. Internal vulcanized traction battery When charging, the initial single voltage can rise to about 2.8V, the electrolyte temperature is also high, as charging continues, after a few hours, the single voltage dropped to 2.2V, and later rising The same is the same as good battery charging. The internal severe vulcanized battery, the voltage of the single battery will be higher than 2.8V, the specific gravity of the electrolyte is not raised, the battery will take a bubble phenomenon at the beginning of charging.
(3) The active substance is falling off. When the battery of the active material is severely detached, the electrolyte turbid, the battery capacity is reduced, and the battery is normal.
(4) Discharge itself. The traction battery of the self-discharge, the charging time is long, and the electrolyte specific gravity and the end voltage rise are slow. If there is a severe short circuit inside the battery, no matter how long the charging time is long, the specific gravity of the electrolyte does not rise, and there is no bubble in the battery, and the electrolyte is like a pangry.
