Embodiment 1

[0030] By attaching figure 1 It can be seen that the present invention is a fast charging energy storage system device for electric vehicles. A fast charging energy storage system is provided in the electric vehicle. The fast charging energy storage system is a composite energy storage system. The composite energy storage system includes a super capacitor 1 and a battery. 2. The super capacitor 1 and the battery 2 are connected in parallel in the circuit of the energy storage system, and the battery 2 is composed of three battery modules 6 connected in series, and each battery module 6 can be composed of several battery cells in parallel or in series; There is a rectifier device 4 in parallel next to the super capacitor 1, and the super capacitor 1 is wired or wirelessly connected to the peripheral power source 3 through the rectifier device 4 during the short stay of the electric vehicle; and during the short stay of the electric vehicle, the composite energy storage system The...

Embodiment 2

[0036] The principle of the second embodiment is the same as that of the first embodiment, except that the driving motor or electrical equipment is powered by two battery modules. One of the two battery modules provides power for the driving motor or electrical equipment, and the other is powered by the super Capacitors charge it; the connections on the periphery of the two battery modules are controlled by switches Km1, Km2, Km3, Km4, Km5, where Km1 and Km2 are power supply connection switches for electrical equipment (or electric vehicles), Km1 Km2 and Km2 are respectively connected to the incoming and outgoing lines of the battery module. Km3 is the power supply isolation switch of the battery module m. Km3 is connected in parallel to the battery m and connected to the incoming and outgoing lines outside of Km1 and Km2. Km4 and Km5 are connections The super capacitor performs a charging connection switch for the battery module m, and Km4 and Km5 are respectively connected to ...

Abstract

The invention discloses a super capacitor and storage battery combined electromobile quick charging method and device. A combined energy storage system with a super capacitor and a storage battery combined is adopted, and during short delay of running of an electromobile, the combined energy storage system is connected with a peripheral power supply in a contact mode and a non-contact mode, and the super capacitor in the combined energy storage system quickly acquires electric energy from the peripheral power supply; after the combined energy storage system is disconnected from the peripheral power supply, the super capacitor in the combined energy storage system transmits the electric energy obtained in a short time to the storage battery in the combined energy storage system; after a number of times of short-time connection and disconnection happen between the super capacitor in the combined energy storage system and the peripheral power supply, the combined energy storage system can quickly store a large capacity of the electric energy, and accordingly the electromobile can be quickly charged in a large capacity during the driving process. The method and device can be applied to other similar mobile electrical products and devices.

Description

Technical field [0001] The invention relates to a charging method and device for electric vehicles, in particular to a fast charging method and device for electric vehicles based on the combination of super capacitors and accumulators; it is mainly used to solve the current problems of difficult and long charging time for electric vehicles. Applicable to other mobile electrical products and equipment. Background technique [0002] Electric vehicles have the characteristics of environmental protection, alternative to petroleum, and diversified sources of electric energy. As a new energy vehicle, it has been recognized by many countries. At present, the significance, necessity and urgency of the development of electric vehicles have been A consensus has been reached; however, there are still many bottlenecks in the development of electric vehicles. The long charging and swapping time and imperfect charging and swapping facilities are one of the most important factors. In early 2010...
