The invention aims to provide a battery module, a power battery, an electric vehicle and an emergency power taking method of the electric vehicle. The battery module comprises a first battery monomer group and two electricity-taking wires, the first battery monomer group comprises a plurality of battery monomers connected in series, and the two electricity-taking wires comprise a positive electrode electricity-taking wire and a negative electrode electricity-taking wire which are respectively led out from the first battery monomer group and are electrically connected with the first battery monomer group; and the other end of the electricity-taking wire electrically connected with the first battery monomer group is provided with a joint. The power battery is connected with the low-voltage storage battery in the electric vehicle through the positive electrode electricity-taking wire and the negative electrode electricity-taking wire, so that the low-voltage storage battery is charged through the power battery in an emergency state.
本发明的目的在于提供一种电池模组、动力电池、电动车辆及电动车辆应急取电方法。其中,电池模组包括第一电池单体组以及两根取电线,第一电池单体组包括多个串联的电池单体,两根取电线包括正极取电线以及负极取电线,分别自第一电池单体组引出,并与第一电池单体组电连接,取电线与第一电池单体组电连接的另一端具有接头。通过正极取电线以及负极取电线实现将动力电池与电动车辆中的低压蓄电池连接,以实现在应急状态下利用动力电池对低压蓄电池进行充电。
