Network control scheme supporting multiple electric vehicle charging modes

Abstract

The invention discloses a network control scheme supporting multiple electric vehicle charging modes. The network control scheme is characterized in that a three-bus topology structure is involved, and a vehicle controller is used as a gateway and a management center of the structure, wherein a comprehensive information display terminal is simultaneously connected with first and second buses; the first of three buses is a vehicle chassis system bus comprising nodes such as an electronic transmission, a motor controller, an electric power assisting system and a brake boosting system; the second of the three buses is a vehicle body system bus comprising nodes such as an electric air conditioner, a vehicle body control module, a combined instrument panel, a DCDC (direct current-direct current) converter and a fault diagnosis instrument; the third of the three buses is a power management system bus comprising nodes such as a battery management system, a ground charger (interface) and a vehicle-mounted charger. According to the network control scheme, the requirements of the same vehicle on the multiple charging modes can be met.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and more specifically relates to a technical solution for supporting multiple charging modes of electric vehicles. [0002] Background technique [0003] With the development of society, the global automobile output in 2011 was 80.1 million, and China became the world's largest automobile producer with an output of 18.4 million. my country's dependence on oil imports has exceeded 50%. The rapid development of the automobile industry has made the problems of limited oil resources and environmental pollution increasingly prominent, and the soaring price of automobile fuel has become an inevitable trend. This makes electric vehicles attract more and more attention from all walks of life, and electric vehicles have become the direction of future automobile development. One of the key common technical problems in electric vehicles is to solve the problem of energy supply. To solve this pro...

Following the above principles, the socket of the standard DC charging interface is installed on the battery module assembly, and the other end of the plug is redesigned and installed on the vehicle body. The battery module can be removed and charged separately, and the charged battery module can then be loaded into the vehicle. Connect with the plug to realize the split charging mode (that is, the quick change); at the same time, considering that the battery module with limited storage energy cannot fully and conveniently solve the energy supply problem of electric vehicles, if there is no quick change or Under the condition of not wanting to change quickly, it is also necessary to assist the conditions of fast charging and slow charging to increase the energy supply conditions of electric vehicles
