Is it better to charge the electric vehicle battery frequently or to recharge after discharging?
The shallower the discharge, the greater the number of cycles.
Therefore, according to this theory, frequent charging is beneficial to the cycle life, but for the chargers widely used in the market, due to the influence of price factors and technical level, the chargers have the defects of high failure rate, poor reliability and low precision.
Therefore, sometimes frequent charging affects the service life of the battery.
When the battery is discharged and recharged, although the charging times are reduced, there will always be differences between individual batteries during discharge, which may lead to over discharge of some single cells, and the charging acceptance capacity of over discharged batteries will be greatly reduced, resulting in the failure of insufficient charging
In addition, due to recharging after discharge, the charger has a heavy load for a long time and is easy to damage the charger.
Therefore, based on the above, it is reasonable to charge once when the battery discharge is 50-70%, which is good for the use of the battery.
