The invention discloses a battery pack, a control method of the battery pack and a vehicle, and belongs to the technical field of electronics. The battery pack comprises a control module, a battery cell, a liquid leakage detection module and a pre-charging switch module, the liquid leakage detection module is connected with the control module, the liquid leakage detection module is used for sending a liquid leakage signal to the control module when liquid leakage of the battery cell is detected, and the control module is used for starting the battery cell if the liquid leakage signal is received when a starting signal for starting the battery cell is received. And if not, the pre-charging switch module is forbidden to send a pre-charging closing signal to the pre-charging switch module, and the pre-charging switch module is used for forbidding connection of the pre-charging voltage end and the power output end when the pre-charging closing signal is not received, so that the battery cell is forbidden to output the pre-charging voltage through the power output end. In the power-on starting stage, if the control module receives the liquid leakage signal, the battery cell can be controlled to prohibit outputting the pre-charging voltage, the battery pack can be prevented from being started in the liquid leakage state, and therefore the battery pack can be effectively protected.
本申请公开了一种电池包、电池包的控制方法和车辆,属于电子技术领域。电池包中包括控制模块、电芯、漏液检测模块和预充开关模块,漏液检测模块与控制模块连接,漏液检测模块用于在检测到电芯发生漏液时,向控制模块发送漏液信号,控制模块用于在接收到启动电芯的启动信号时,若接收到漏液信号,则禁止向预充开关模块发送预充闭合信号,预充开关模块用于在未接收到预充闭合信号时,禁止连接预充电压端和电源输出端,以禁止电芯通过电源输出端输出预充电压。在上电启动阶段,控制模块若接收到漏液信号,可以控制电芯禁止输出预充电压,可以避免电池包在漏液状态下启动,从而可以对电池包进行有效的保护。
