Abstract

The invention discloses a high-voltage control device for a power battery. The high-voltage control device comprises a plurality of positive pole electric devices, a plurality of negative pole electric devices and a shell. The positive pole electric devices comprise a Hall sensor, a relay and a connector assembly. The Hall sensor is connected with the relay which is connected with the connector assembly, and the Hall sensor is connected with the positive pole. The negative pole electric devices comprise a precharge relay and a precharge resistor connected with the precharge relay. The precharge relay is connected with the negative pole. A positive pole mounting area and a negative pole mounting area are formed in the shell and spaced from each other. The positive pole electric devices are mounted in the positive pole mounting area and spaced from one another, and the negative pole electric devices are mounted in the negative pole mounting area and spaced from each other. Due to the arrangement of the shell, the requirements for safety and insulativity of the high-voltage control device can be met; in addition, the space, occupied by the high-voltage control device, of the power battery can be reduced.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a high-voltage control device for power batteries. Background technique [0002] The power battery can provide a source of power for electric vehicles. The battery pack is composed of multiple single cells. A circuit distribution control device is designed at the terminals of the total positive and total negative. These devices mainly include relays, fuses, and pre-charging relays. , pre-charging group and current sensor and other components, the main function is to control the circuit input and output of the battery pack, and realize power distribution for the power system. [0003] In the related art, most of the high-voltage control devices adopt the method of fixing the electrical components separately, but in order to ensure the insulation gap, creepage gap and safety requirements, the high-voltage control device has the following disadvantages: 1. Large waste of spa...
