Embodiment Construction

[0022] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0023] see figure 1 , The electric vehicle on-board power generation system of the present invention includes: an engine 1 , an electric motor 2 , a rectification control unit 3 , a vehicle control unit 4 , a battery management unit 5 and a battery pack 6 . The engine 1 and the motor 2 are coaxially and rigidly connected into one body. The motor 2 is the power drive unit of the electric vehicle, which converts electric energy into kinetic energy to drive the vehicle; the engine 1 is responsible for burning gasoline or diesel to generate electricity when the vehicle battery is low. , output electric power to charge the battery. Preferably, the engine 1 and the electric motor 2 can adopt an inspiring integrated motor, and the inspiring integrated mot...

Abstract

The invention provides a vehicle-mounted power generating system for an electric vehicle. The power generating system comprises an engine (1), a motor (2), a rectification control unit (3) and a battery pack (6), wherein the engine (1) and the motor (2) are integrally and rigidly connected together; and the engine (1) is electrically connected with the battery pack (6) through the rectification control unit (3) and used for charging the battery pack (6). In the invention, the electric vehicle is equipped with the engine in coaxially rigid connection with the motor, and the engine is an internal combustion engines which can charge batteries when power of the batteries is low, so that the journey continuing capability of a conventional electric vehicle is greatly improved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an on-board power generation system of the electric vehicle. Background technique [0002] As a major category of new energy vehicles advocated by the country, electric vehicles have the characteristics of new technologies and new structures. However, the current technical bottleneck lies in power storage technology, and the driving range cannot meet the requirements of mass consumption. The implementation schemes of the prior art include: 1. a dual-drive hybrid electric scheme; 2. a scheme for fast charging or battery replacement. However, there are obvious defects in both schemes: among them, the dual-drive hybrid electric scheme is to add a set of motor drive on the basis of the mechanical drive of the original piston engine power, which requires a larger car body size to meet the needs of the piston engine, machinery and The arrangement of the motor drive assembly, battery p...
