Abstract

The invention discloses an integrated switching device for a low-voltage platform of an electric vehicle, which includes a protective case, a PCB board and a connector, the connector is installed on one side of the protective case, the PCB board is arranged in the protective case, and multiple The positive pole of some of the diodes is connected to the battery power supply, and the negative pole is connected to the electrical equipment; the positive pole of the other part of the diode is connected to the charging auxiliary power supply, and the negative pole is connected to the electrical equipment. The invention can work in the discharge state or charge state of the vehicle, and can convert the current signal into a voltage signal, and has wide application range, strong compatibility, low price and convenient installation.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and more particularly relates to an integrated switching device for a low-voltage platform of an electric vehicle. Background technique [0002] Some parts of an electric vehicle need to be able to work in both the discharge state and the charge state, so it is necessary to provide power to these parts in both the discharge state and the discharge state. However, in the charging state, the low-voltage battery of the vehicle provides power to these components; in the charging state, the charging auxiliary power supply provides power to these components, and the charging auxiliary has a fast charging auxiliary power supply and a slow charging auxiliary power supply. Therefore, it is impossible to directly supply a single power supply to the components that need to be powered. [0003] Therefore, how to provide an integrated switching device for a low-voltage platform of an electric vehic...
