Embodiment 1

[0045] figure 1 It is a schematic diagram of a device combining a super capacitor and an exchangeable battery pack to drive an electric vehicle provided by an embodiment of the present invention. Such as figure 1 As shown, the structure of the device is:

[0046] One or more removable battery packs 1. In this embodiment, the number of battery packs 1 is two;

[0047] In the docking socket 2, each docking socket can be easily inserted into a removable battery pack 1; the multiple battery packs 1 inserted into the docking socket 2 can be connected in parallel or in series to form an exchangeable battery pack energy storage system, It should be noted that, in this embodiment, one battery pack 1 corresponds to one socket 2 as an example. It is not difficult to think that one socket 2 corresponds to two battery packs 1, or there are sockets 2 that do not correspond to battery pack 1, etc. The details are not here. Make a limit.

[0048] Through the docking socket 2, the mobile battery p...

Embodiment 2

[0061] On the basis of the first embodiment, the present invention provides an exchangeable mobile battery pack, which is suitable for the device provided by the present invention that combines supercapacitors and exchangeable battery packs to drive electric vehicles; the movable battery pack It is composed of multiple high-energy lithium batteries in series and / or in parallel; in this embodiment, the movable battery pack weighs 10-20kg, and the stored energy after charging is about 5-10kWh, and the voltage is 180 -360V, the discharge current is 1-120A, the battery pack is equipped with a power indicator 12. The electric energy stored in the battery pack is enough to support an electric vehicle to travel about 50-100km.

[0062] Structure of removable battery pack

[0063] Refer to Figure 3 for the specific structure of the removable battery pack. Since this battery pack needs to be easily taken out of the vehicle for independent charging, its weight cannot be too large, and it m...

Embodiment 3

[0074] On the basis of the above-mentioned embodiments, the present invention also provides an electric vehicle equipped with the above-mentioned device that combines a super capacitor and an exchangeable battery pack to drive the electric vehicle. In this embodiment, the device includes figure 1 The various components shown and the modes of operation described in the above embodiments.

[0075] The above-mentioned electric vehicle equipped with a device that combines a supercapacitor and an exchangeable battery pack to drive an electric vehicle can not only be charged using a charging pile like the traditional method, but also can take out the movable battery pack 1 from the vehicle. According to the situation, Flexible choice of different power sources for independent charging outside the car. In this way, electric vehicles can be used in the absence of charging piles.

[0076] As a preferred embodiment, the number of docking sockets 2 is specifically 1-8. Each docking socket 2...

Abstract

The invention relates to an energy storage / charging device combining a supercapacitor and exchangeable battery packs and an electric vehicle driven by the energy storage / charging device. The device comprises the supercapacitor and the plurality of exchangeable battery packs; and each battery pack is installed in one corresponding butt-joint socket on the electric vehicle and can be easily taken out from or inserted into the socket. According to the device, a motor in the electric vehicle is not directly driven by the battery packs, and but is powered by the means of controllable parallel connection between the battery packs and the supercapacitor. The battery packs in the vehicle can be charged by charging piles used by common electric vehicles and can also be taken out to be independentlycharged outside the vehicle; a user can use different types of charging power sources including a household power source, a direct-current fast charging power source and a photovoltaic power source.In specific operation, the changeable battery packs serve as the energy carriers of the electric vehicle. By means of technical extension, the electric vehicle can conveniently carry out short-distance and long-distance driving.

Description

Technical field [0001] This application relates to the technical field of electric vehicles, in particular to an energy storage / charging device that provides electric energy for electric vehicles, including reusable battery packs, super capacitors, and electric vehicles using the device. Background technique [0002] In recent years, electric vehicles have become a key support industry in many countries. This is because electric vehicles have many advantages, including energy saving, environmental protection, economy and so on. However, the electric vehicles currently in use have a big disadvantage, that is, charging is inconvenient. First of all, the current charging time of electric vehicles is generally relatively long, from one hour to twenty hours. Secondly, charging piles are not popular, and they may not be found when needed; even if they are found, they may have to wait in line. Third, it is difficult to use electric vehicles for long-distance travel. The endurance of...
