The embodiment of the invention provides a power battery and an electric vehicle. The electric vehicle comprises a water tank, a first cooling loop, a second cooling loop and a power battery. The first cooling loop communicates with the water tank, and the second cooling loop is used for communicating with cooling equipment outside a vehicle. The water tank comprises a filling port and a filling cover covering the filling port. Wherein the electric vehicle is used for sending a message for instructing the cooling equipment outside the vehicle to output the cooling liquid when the filling cover is not opened in a time period from receiving the cooling liquid output by the cooling equipment outside the vehicle to connecting the cooling equipment outside the vehicle again; or when the filling cover is opened, the message used for indicating the cooling device outside the vehicle to output the cooling liquid is not sent, or the message used for indicating the cooling device outside the vehicle not to output the cooling liquid is sent. According to the embodiment of the invention, the second cooling loop of the electric vehicle can utilize the cooling liquid provided by the cooling equipment outside the vehicle to dissipate heat of the power battery, and meanwhile, the polluted cooling liquid in the water tank is prevented from diffusing to the cooling equipment outside the vehicle.
本申请实施例提供一种动力电池和电动车辆。电动车辆包括水箱、第一冷却回路、第二冷却回路和动力电池。第一冷却回路与水箱连通,第二冷却回路用于连通车外冷却设备。水箱包括加注口、以及盖合于加注口的加注盖。其中,电动车辆用于在接收车外冷却设备输出的冷却液到再次连接车外冷却设备的时间段内:当加注盖未被打开过,发送用于指示车外冷却设备输出冷却液的报文;或者,当加注盖被打开过,不发送用于指示车外冷却设备输出冷却液的报文,或发送用于指示车外冷却设备不输出冷却液的报文。本申请实施例可以在使电动车辆的第二冷却回路利用车外冷却设备提供的冷却液为动力电池散热的同时,也防止水箱中被污染的冷却液扩散到车外冷却设备。
