The invention discloses a power battery high-voltage distribution box, a power battery and a vehicle. The technical problem that in the prior art, a distribution box is low in heat dissipation performance is solved. The power battery high-voltage distribution box comprises a shell and an electrical unit installed in the shell, and the electrical unit comprises a copper bar assembly and more than one temperature sensor. The temperature sensor is located in the inner cavity of the shell and is used for monitoring and recording the temperature of an internal key position in real time and monitoring, collecting and reporting the temperature in real time; the copper bar assembly is bent towards one side of the shell so that part of the copper bar assembly can be exposed out of the shell, and the part, exposed out of the shell, of the copper bar assembly can make contact with an external cooling assembly so that cooling can be conducted. The power battery high-voltage distribution box provided by the invention adopts a scheme of internal temperature monitoring and copper bar active cooling, so that the heat dissipation performance of the distribution box is improved, the temperature in the distribution box is collected and monitored in real time, the temperature of the distribution box is ensured to be normal, the current-carrying capability is improved, and the problems of ablation and fire are prevented.
