Battery health state prediction method and device, electronic equipment and program product

The invention provides a battery health state prediction method, a battery health state prediction device, electronic equipment and a program product. Calculating a first battery health degree in the current state based on the battery basic parameters of the to-be-tested battery in the current state and the nominal self-discharge rate of the to-be-tested battery; when the to-be-tested battery is in the discharge state, calculating a second battery health degree of the to-be-tested battery based on the battery basic parameters of the to-be-tested battery in the current state and the preset full charge capacity; and predicting the current health state of the to-be-tested battery based on the second battery health degree and the first battery health degree under the condition that the to-be-tested battery reaches a preset updating condition. The method can accurately predict the health state of the battery in real time, and is less affected by the discharging and charging processes of the battery. 本申请提出一种电池健康状态预
