Electric automobile power supply free of external charging

Abstract

The invention discloses an electric automobile power supply free of external charging. The electric automobile power supply comprises an energy storage cell which is used for charging a power cell or directly driving a motor, an energy storage cell control unit which is used for controlling the energy storage cell and adjusting the start and stop and the output power of the energy storage cell by controlling the gas, water and heat inside the energy storage cell, the power cell which is used for directly providing electric energy for the motor and maintaining the normal rotating power of the motor in an electric automobile through receiving the electric energy which is provided by the energy storage cell, a power cell management unit which is used for controlling the discharging and the charging of the power cell, a DC (Direct Current)/DC (Direct Current) converting unit which is used for converting the direct current voltage which is fluctuant in a fixed range into the voltage which can be loaded on the power cell, and a power system control unit which is used for adjusting the power generation of the energy storage cell and the charging and discharging of the power cell, and providing the electric energy for the motor. According to the electric automobile power supply free of external charging, a fuel cell is used as the energy storage cell and used for assisting electricity supply, the real-time charging of the electric automobile is realized, and an external charging interface is not needed.

Description

technical field [0001] The invention relates to a power source, in particular to an electric vehicle power source without external charging. Background technique [0002] The world's tight energy supply and environmental pollution have forced human beings to start upgrading automobile power batteries and explore alternatives to traditional fuel power systems. Pure electric vehicles powered by batteries such as lithium batteries, lead-acid batteries or supercapacitors have become a research hotspot due to their unique advantages. However, due to the small energy storage of this type of battery, the cruising range of the electric vehicle is short, and the charging time of the battery itself is long, so that it cannot be widely used. [0003] Fuel cell vehicles, which use fuel cells as the main power source, have the advantages of high energy conversion efficiency, zero emission of engine exhaust, and modular integration. The working characteristics of stable external power s...

Problems solved by technology

However, due to the small energy storage of this type of battery, the cruising range of electric vehicles is short, and the charging time of the battery itself is long, so that it cannot be widely used.

[0003] Fuel cell vehicles, which use fuel cells as the main power source, have the advantages of high energy conversion efficiency, zero emission of engine exhaust, and modular integration. The working characteristics of stable external power supply based on electrochemical equilibrium reaction have seriously affected the stability and service life of fuel cells, and thus hindered the promotion of fuel cell vehicles
