Abstract

The invention discloses a power battery comprising a high-voltage protector. The power battery comprises a high voltage power distribution system, a battery management system and a battery pack system, wherein a power input of the high voltage power distribution system is connected with a power output of the battery pack system through a connector, and a power output of the high voltage power distribution system is connected with a plurality of loads through a plurality of connectors. A power control terminal of the high voltage power distribution system is connected with a power control terminal of the battery management system through a connector, and a control input of the high voltage power distribution system is connected with a control output of a superior controller through a connector. The power battery system not only comprises the battery management system and the battery pack system, but also comprises the high voltage power distribution system, so that the problem of multiple wire harnesses is effectively solved, the integration level of the power battery is improved, and the size of the power battery can be smaller. The power battery has the functions of loop protection, pre-charge, and overcurrent protection. The power battery also has a real-time maintenance switch, so that the safety of workers can be ensured during the battery maintenance.

Description

technical field [0001] The invention relates to the field of power batteries, in particular to a power battery that integrates a high-voltage protection device and provides power supply and distribution for new energy vehicles. Background technique [0002] Today's world energy crisis and environmental problems continue to intensify, making the development of new energy and environmentally friendly vehicles a mainstream trend for car companies. New energy vehicles can not only bring convenience to people like traditional vehicles, but also can effectively solve the energy and environmental protection problems faced by the automobile industry. [0003] As the main power source of the vehicle, the power battery is a very core component of the vehicle, and it is also the main object of development and research for the development of new energy vehicles. At the same time, its safety is also a key factor that must be considered. [0004] Traditional power battery systems include...
