METHOD AND APPARATUS FOR DETECTING STATE OF HEALTH OF BATTERY, AND ELECTRONIC DEVICE AND STORAGE MEDIUM

摘要

A method and apparatus for detecting state of health of a battery, and an electronic device and a storage medium. The method comprises: obtaining a first energy value released by a target battery in a full-charge state (S101); obtaining type information of the target battery, and querying a second energy value released by the target battery under the nominal capacity from a correspondence table between the preset battery type and the energy value released by the battery under the nominal capacity (S102); and calculating a ratio of the first energy value to the second energy value to generate a state of health value of the target battery (S103). According to the detection method, from the perspective of energy, the discharge capacity of the target battery is solved, the state of health value of the target battery is obtained by calculating the ratio of the discharge capacity of the target battery to the discharge capacity of the target battery under the nominal capacity, a complex mathematical model is not needed in the calculation process, no rigid requirement is needed for the constant-current load, the precision is high, and the requirement for detection devices is low.
