The invention discloses a solar trickle energy supplementing device and method for preventing power shortage of an automobile storage battery. The device comprises the storage battery, a storage battery state monitoring circuit, a pre-comparison circuit, a solar cell panel, a solar charging control circuit and an anti-reverse charging circuit. The current current, voltage and temperature of the storage battery are determined through the storage battery state monitoring circuit; the current SOC value is compared with an SOC threshold value for preventing power shortage of the battery through the pre-comparison circuit, and when the current SOC value is lower than the SOC threshold value, the solar charging control circuit is started; after the solar charging control circuit is started, thesolar charging state is controlled by detecting whether the current voltage exceeds the upper charging cut-off voltage or not, if yes, charging is stopped, and if not, charging is continued; and the storage battery is prevented from reversely electrifying the solar cell panel through the anti-reverse charging circuit. The invention provides a method for monitoring, calculating and keeping the current SOC value of the storage battery to be greater than the SOC threshold value for preventing power shortage of the storage battery in a trickle energy supplementing manner, so that the power shortage of the storage battery is prevented, and the service life of the storage battery is prolonged.
本发明公开了一种预防汽车蓄电池亏电的太阳能涓流补能装置及其方法,该装置包括蓄电池、蓄电池状态监测电路、预比较电路、太阳能电池板、太阳能充电控制电路和防反充电路;通过蓄电池状态监测电路确定蓄电池的当前电流、电压与温度;通过预比较电路对当前SOC值与预防电池亏电的SOC阀值比较,当判断为小于时,开启太阳能充电控制电路;太阳能充电控制电路开启后,通过检测当前电压是否超过充电上截止电压来控制太阳能充电状态,若是,则停止充电,若否,则继续充电;通过防反充电路防止蓄电池对太阳能电池板反向通电。本发明提供了监测计算并通过涓流补能的方式保持蓄电池当前SOC值大于预防电池亏电的SOC阈值的方法,从而预防蓄电池亏电,延长其寿命。
