Abstract

The invention relates to a wireless sensing charging system for a composite multifunctional power supply of an electric vehicle. The invention discloses a core technology solution, which carries out capability transmission through a sensing mode to have power storage and regulation and control effectively and solves the technology problem that the charging speed for the electric vehicle is slow so as to realize wireless connection charging for the electric vehicle when in working. Simultaneously, different energy storing technologies and different energy storing types are combined and optimized, and a complete power conversion and control system compounded with power regulation and control having different energy storing technologies and different energy storing types is formed together with reasonable control scheme and control mechanism, that is, an intelligently compounded high-capacity battery with quick charging and discharging characteristic capable of obtaining energy supplement at any time can be formed, thereby enabling the electric vehicle and other vehicles to have excellent power performance, long time and long distance running capability.

Description

technical field [0001] The invention is a wireless inductive charging technology for energy accumulators, a technology and device especially suitable for energy supply, replenishment, storage and control of hybrid power electric vehicles and vehicles. Background technique [0002] Due to the limited reserves of petroleum energy substances, with the rapid expansion of industry, economy and consumption, the current supply of petroleum is increasingly tight, especially the future development of traditional fuel-powered vehicles will be severely restricted. It is imperative to develop new high-efficiency vehicles that utilize different forms of energy. [0003] Electric vehicles are one of the most promising alternatives to conventional gasoline vehicles. The power supply is an important core part of an electric vehicle. The common on-board power supply of an ordinary electric vehicle is an ordinary lead-acid or lithium battery. These batteries all have a common characteristic...
