[0075] See attached figure 1 , This embodiment relates to an electric vehicle. The electric vehicle shown in the figure is merely exemplary, and the actual configuration of the electric vehicle is not limited to the configuration shown in the figure.

[0076] The electric vehicle 52 includes a vehicle body 52a and a battery assembly 50 that is detachably housed in the vehicle body. The vehicle body 52a includes a vehicle body 74, and the vehicle body 74 is provided with an electric motor 76 for driving one or more wheels 52b to move. The battery assembly 50 provides electric power to the electric motor 76. The battery assembly 50 is electrically and mechanically connected to the vehicle main body 52a, so as to provide electrical energy for the functions of the vehicle such as driving, lighting, audio, and air conditioning.

[0077] It should be noted that the electric vehicle 52 mentioned here may be a pure electric vehicle that is completely powered by battery components, or a h...

[0098] See attached Figure 7 , This embodiment relates to an electric vehicle.

[0099] The same parts as the electric vehicle in the first embodiment will not be repeated here, and only the differences between the electric vehicle 52 and the first embodiment will be described.

[0100] In this embodiment, the electric vehicle 52 includes a vehicle body 74, an electric motor 76 housed in the vehicle body 74, a battery assembly 50' that provides power to the electric motor, and a cover 72 that covers the battery assembly in the vehicle body.

[0101] When the battery assembly 50' is installed on an electric vehicle, the cover 72 is basically located below the battery assembly 50' and at least partially covers the battery assembly 50'. Preferably, the size of the cover plate 72 is larger than the size of the battery assembly 50', so that the cover plate 72 can completely cover the battery assembly 50'. The cover plate 72 is relatively fixedly connected to the battery assembly 50', so...

[0105] See attached Figure 8 Compared with the electric vehicle in the second embodiment, the electric vehicle in this embodiment includes a plurality of cover plates 72, and each cover plate is provided with at least one battery module 56. The battery module 56 includes at least one rechargeable battery 58 and a wireless power receiving device 60. The cover 72 is removed together with the wireless power receiving device 60, and the battery assembly can be easily replaced.

[0106] The electric vehicle in this embodiment includes a battery assembly 50'. The battery assembly 50 includes at least one rechargeable battery 58, a wireless power receiving device 60 and a cover 72. The entire battery assembly 50' is integrally removed with respect to the vehicle body 74 to realize convenient replacement of the battery assembly. At the same time, the wireless power receiving device is removed and installed together with the cover plate, and the design of the battery replacement device ...

Abstract

Provided is a battery assembly. The battery assembly is used for supplying power to an electric vehicle and comprises a plurality of battery modules, each battery module comprises at least one rechargeable battery and a wireless electric energy receiving device, and the battery modules are overall detachably connected with a vehicle body. The invention further discloses the electric vehicle with the battery assembly and a power source system. The battery assembly is convenient to replace and is charged in a wireless mode, and energy supplementation is fast.

Description

Technical field [0001] The invention relates to a battery assembly, an electric vehicle and a power supply system. Background technique [0002] Commonly used secondary rechargeable batteries for electric vehicles include lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries and lithium-ion batteries. The battery energy replenishment methods of electric vehicles include the following. The first is to replenish battery energy by connecting a charging pile. In this mode, the battery capacity is fully restored, but the energy replenishment time is long. Another way to replenish battery energy is to replace the battery, that is, to replace the depleted battery with a fully charged battery. This mode takes a short time to replenish energy. The battery replacement process only takes a few minutes, which solves the user’s long-term charging The question of waiting. On the other hand, with the maturity of wireless charging technology, it has become a development tren...
