The invention relates to a battery pack information acquisition device and a power supply method thereof, and belongs to the technical field of battery system management. The power supply method comprises the steps that 1) the state of the battery pack information acquisition device is judged; 2) when the battery pack information acquisition device is in a dormant state, a first power supply branch is adopted to supply power to the battery pack information acquisition device; and when the battery pack information acquisition device is in a wake-up state, a second power supply branch is adopted to supply power to the battery pack information acquisition device. According to the invention, the strategy that different power supply branches supply power in a time-sharing manner is adopted, the problems of high cost and low power supply efficiency caused by the fact that the same power supply branch is adopted to meet the power supply requirements in the two states at the same time in the prior art can be solved, and the power supply effect is improved.

    本发明涉及一种电池包信息采集装置及其供电方法,属于电池系统管理技术领域。供电方法,包括以下步骤:1)判断电池包信息采集装置所处状态;2)当电池包信息采集装置处于休眠状态时,采用第一供电支路为电池包信息采集装置供电;当电池包信息采集装置处于唤醒状态时,采用第二供电支路为电池包信息采集装置供电。本发明采用由不同供电支路分时进行供电的策略,能够解决现有由于采用同一供电支路同时满足上述两种状态下供电需求所导致的成本较高和供电效率较低的问题,提高了供电效果。
