Abstract

The invention relates to an electromobile hybrid battery-driven system and belongs to a power-driven system for an electromobile, and the system can be used for solving the problems that the output load power of the existing solar battery and storage batter combined hybrid power source is fixed and the output power of a solar battery in the power source is unstable. The electromobile hybrid battery-driven system disclosed by the invention comprises a first storage battery, a vehicle-mounted charging system, a first direct current converter, a second storage battery, a second direct current converter, a solar battery pack, a third direct current converter, a permanent magnetic synchronous motor, a driving controller, a vehicle condition feedback device and an engine control unit. The electromobile hybrid battery-driven system disclosed by the invention can automatically regulate the output power of the solar battery pack and a storage battery pack according to requirement of load power, when the output power of the solar battery pack is insufficient, the storage battery pack is automatically started to supply power, thus optimal coordination of the output power is realized, the problems that the output load power of the existing solar battery and storage battery combined hybrid power source is fixed and the output power of the solar battery in the power source is unstable are solved, and the system can adapt to the power supply requirement of the electromobile.

Description

technical field [0001] The invention belongs to an electric driving system of an electric vehicle, in particular to a hybrid battery driving system of an electric vehicle. Background technique [0002] Due to the increasing shortage of fuel resources and vehicle emissions, energy-saving and environmentally friendly electric vehicles have become the future development trend of new energy vehicles. A hybrid vehicle with a hybrid power source combined with an internal combustion engine and a storage battery belongs to the category of "energy-saving vehicles". Although this scheme has improved the environment and energy saving, it still cannot get rid of the dependence on fuel resources and the damage to the environment. [0003] Battery electric vehicles using batteries alone as the power source have made great progress, but limited by the volume and capacity of the batteries, the distance that can be driven per charge is limited, which is very inconvenient to use; and the bat...
