A spare rechargeable battery box

Abstract

The invention provides a spare rechargeable battery box, which includes a shell, and the inside of the shell is designed with a main cavity, a spare cavity, and a charging cavity; the charging cavity is equipped with a A power conversion device, the power conversion device is designed with a USB interface; the middle of the outer wall of the housing is designed with a water-filled fireproof layer, and the backup cavity is designed with a connection joint in parallel with the main battery pack of the main cavity . This spare rechargeable battery box is used on electric vehicles, and the main battery pack can be used to supply power alone, which can reduce the weight of the entire battery and improve the utilization rate of electric energy. Provide power supply for electric vehicles. The charging cavity can charge electronic products such as mobile phones and the like through the USB interface on the power conversion device.

Description

technical field [0001] The invention relates to the technical field of electric appliance parts, in particular to a spare rechargeable battery box. Background technique [0002] Generally speaking, electric vehicles use batteries as energy sources, and convert electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed. The electric vehicles we usually use are all power-assisted electric bicycles. The biggest feature of electric vehicles is to use batteries to power electric vehicles. The batteries are also called storage batteries and are usually assembled in the battery box. The battery box is usually made of plastic material, and it is designed with a single cavity in which the battery modules are assembled in series or in parallel as required. Connection between electrical equipment. The battery module will generate a lot of heat when it is charging, especially when it is overcharged, and when t...

AI Technical Summary

Problems solved by technology

[0003] Storage batteries, especially the lead-acid batteries that are now widely used by people, are relatively heavy, which greatly increases the quality of the entire electric vehicle, makes the running resistance of the electric vehicle larger, and causes a waste of electricity

However, if too few batteries are used, the battery life of the electric vehicle is too small, which is difficult to meet people's requirements.

Electric vehicles rely on batteries to provide power to run, and when the power in the batteries is exhausted, electric vehicles, especially electric vehicles without pedals, can only rely on pushing, which is very laborious

Now people use a lot of electronic devices such as mobile phones, tablets and mp3. As the display screen becomes larger and larger, the power consumption is also increasing. When the batteries of these electronic devices are exhausted, they cannot work. Charging can be done well in any place
