Charging method of asymmetric hybrid power supply device for extended-range small electric vehicle

Abstract

The invention provides a charging method of an asymmetric hybrid power supply device for an extended-range small electric car and belongs to the field of electric car equipment. The charging method uses a battery pack, a power generation device and a load, wherein the power generation device is connected with the battery pack, and the battery pack and the power generation device are simultaneously connected with the load. The charging method is characterized in that a control device which is composed of a traveling and alarm display device, a switch knob and a controller and used for monitoring and controlling working states of the battery pack and the power generation device is arranged, the traveling and alarm display device is simultaneously connected with the switch knob and the controller, the switch knob is connected with the power generation device, and the controller is connected with the battery pack. The charging method of the asymmetric hybrid power supply device for the extended-range electric car is simple in structure, reliable in performance and capable of achieving large-current rapid charging and discharging. In normal traveling of the extended-range small electric car, an engine can supply electricity to and charge the battery pack when electricity of the battery pack is not enough. By means of the charging method, people can select charging modes.

Description

technical field [0001] The invention relates to a charging method for an asymmetric hybrid power supply device for an extended-range small electric vehicle, which belongs to the technical field of electric vehicles. In particular, it relates to a charging method of an asymmetric oil-electric hybrid power supply device using a capacitive power battery and a generator and a control system for realizing the control method. Background technique [0002] At present, the hybrid power supply devices on the market mainly use supercapacitors, lithium batteries and other batteries in combination, and the devices that use oil-electric hybrid use mainly use oil, and batteries can only be used in specific environments. Some of them are small portable mobile hybrid power supplies. For pure electric vehicle hybrid power supplies, the market has not yet met the needs, mainly because the current generated by pure electric vehicles during operation is unstable, which causes the battery to rec...

[0002] At present, the hybrid power supply devices on the market mainly use supercapacitors, lithium batteries and other batteries in combination, and the devices that use oil-electric hybrid use mainly use oil, and batteries can only be used in specific environments. Some of them are small portable mobile hybrid power supplies. For pure electric vehicle hybrid power supplies, the market has not yet met the needs, mainly because the current generated by pure electric vehicles is unstable during operation, which causes the battery to receive current shocks during charging and discharging. Larger, higher requirements on the power performance of the battery; and the fast charging and discharging performance of the power battery is poor, the safety is poor, and the price is relatively expensive. Calculated, the cost of use is very high
