The specific preset energy data and health state incidence relation is that the real-time health state of the storage battery is determined according to the ratio of the energy supplement energy to the chargeable energy, and the real-time health state refers to the health state of the storage battery after the charging is finished. After the health state of the storage battery is determined and converted, the health state of the storage battery can be stored in a battery management system, so that the health states of the storage battery in different time periods can be obtained in real time through the battery management system.
As shown in fig. 2, to complete the power supply to the storage battery, the main components may include: 1. the power battery is a high-voltage power source of the system; 2. the battery end high-voltage box is a main switch for outputting the electric power of the battery end; 3. the whole vehicle end high-voltage box is a whole vehicle end battery input main switch; 4.

In order to ensure the safety of the power supply process, the whole vehicle controller is required to control the whole vehicle to complete self-detection, high voltage and enabling of a voltage converter before power supply is carried out; when the self-checking, the upper high voltage and the voltage converter are enabled, the BMS is informed of the fact that electricity can be supplemented, the power battery is controlled to supplement electricity for the storage battery, and if serious faults of the whole vehicle occur in the electricity supplementing process, the electricity supplementing process is ended, and electricity supplementing operation can be carried out only on the premise of ensuring safety.
