METHOD FOR MEASURING BATTERY RESERVE CAPACITY OF STORAGE BATTERY, AND BATTERY DETECTION DEVICE

A method for measuring a battery reserve capacity of a storage battery (200), and a battery detection device (100). The method for measuring a battery reserve capacity of a storage battery (200) is applied to a battery detection device (100). The battery detection device (100) is electrically connected to the storage battery (200) by means of a Kelvin connector. The method comprises: sending an input signal to a storage battery (200) to control the discharging of the storage battery (200), and acquiring an output signal which is fed back, within an input duration of the input signal, by the storage battery (200) regarding the input signal (S41); determining a target battery parameter according to the output signal (S42); acquiring a battery capacity table, wherein the battery capacity table comprises a correlation between a battery parameter and a battery reserve capacity (S43); and according to the battery capacity table and the target battery parameter, determining a battery reserve capacity corresponding to the target battery parameter (S44). The measurement time for a battery reserve capacity of a storage battery (200) is reduced, and the measurement efficiency is improved.
