    摘要: A method for detecting a storage battery of a vehicle includes: acquiring the noise intensity and battery information of the storage battery; according to the noise intensity and the battery information, selecting a battery detection scheme from among at least two preset candidate battery detection schemes. The battery detection scheme includes one among a discharge load value, detection frequency, duty cycle and detection time, the discharge load value and the detection frequency are related to the noise intensity, and the duty cycle and the detection time are related to the battery information; and detecting the storage battery according to the battery detection scheme. By means of the noise intensity and the battery information, a comprehensive selection of a battery detection scheme may be used to achieve the rapid and accurate detection of the storage battery even in circumstances of noise interference and/or poor health of the storage battery.

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