| description | The invention discloses a lithium ion power battery charging and discharging method, which overcomes the problem of short service life of the battery in the prior art, and comprises a first charging and discharging method and a second charging and discharging method.The first charging and discharging method is to limit the charging power of the lithium iron phosphate battery system, and the secondcharging and discharging method is used for limiting the charging electric quantity and the discharging electric quantity of the ternary and high-voltage ternary battery system. The charging and discharging voltage interval of the battery is strictly limited, the charging and discharging voltage is controlled, charging and discharging under the condition of a low SOC interval are prevented, the internal stress of the battery is reduced drastically, overcharging caused by charging and discharging under the condition of a high SOC interval of the ternary battery is reduced, and the service lifeof the lithium ion batter |
