High-voltage integration module for electric automobile

Abstract

The invention discloses a high-voltage integration module for an electric automobile. A submodule in the high-voltage integration module comprises a complete vehicle controller, a motor controller, a DC-DC converter, a DC-AC converter and a charger; an external port of the high-voltage integration module comprises a low-voltage port, a quick-charge port, a slow-charge port, a ceramic heating PTC port, an air conditioner port, an oil pump port, an air pump port, a positive-keeping negative-keeping port, and a motor triphase port; a connecting network in the high-voltage integration module comprises a high voltage direct current, a high voltage alternating current, a local area network control network CAN bus and a low voltage wire harness. According to different types of automobiles, hardware and port requirement configuration can be performed on the high-voltage integration module disclosed by the invention, and the high-voltage integration module is suitable for different types of automobiles from purely electric cars to purely electric passenger cars. The high-voltage integration module can effectively integrate distributed controllers of the electric automobile, the length of an electric wiring of the electric automobile is shortened, and the architecture of a control module of the electric automobile is simplified.
