The invention relates to an automobile power supply module integrating a BUCK circuit and an LDO circuit and a use method of the automobile power supply module. The automobile power supply module integrating the BUCK circuit and the LDO circuit comprises a battery management system BMS, the LDO circuit used for preventing the BMS from being disturbed and awakened mistakenly and the double-BUCK circuit used for alternately charging a storage battery. A control module of an automobile is connected with the battery management system BMS through the LDO circuit, the battery management system BMS is connected with a power battery, and the power battery is connected with the double-BUCK circuit. The low-cost LDO circuit is adopted to wake up the power management system of the power battery, and the reliability is high; the two BUCK circuits are adopted to charge the storage battery alternately, and the structure is simple; compared with a traditional scheme, the service life of the storage battery can be effectively prolonged, and meanwhile safety is improved.

    本发明涉及一种集成BUCK电路和LDO电路的汽车电源模块及其使用方法,所述集成BUCK电路和LDO电路的汽车电源模块包括电池管理系统BMS、用于防止BMS被干扰误唤醒的LDO电路以及用于交替对蓄电池进行充电的双BUCK电路;汽车的控制模块通过所述LDO电路与所述电池管理系统BMS相连接,所述电池管理系统BMS与动力电池相连接,所述动力电池与所述双BUCK电路相连接。本发明采用低成本的LDO电路,对动力电池的电源管理系统进行唤醒,可靠性强;采用两个BUCK电路交替对蓄电池进行充电,结构简单;相比于传统的方案,可有效增加蓄电池的使用寿命,同时提升安全性。
