Abstract

The invention discloses an integrated switching device for a low-voltage platform of an electric vehicle. The integrated switching device comprises a protective casing, a PCB and a connector, whereinthe connector is mounted on one side of the protective casing, the PCB is arranged in the protective casing, and multiple diodes are integrated on the PCB; positive poles of one part of the diodes areconnected with a battery supply, and negative poles are connected with electric equipment; positive poles of the other part of the diodes are connected with a charging auxiliary power supply, and negative poles are connected with the electric equipment. The device can work when the vehicle under a discharge condition or a charge condition, can convert current signals into voltage signals, has wide application range, high compatibility and low cost and is convenient to install.

Description

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