Problems solved by technology

The advantage of this type of structure is that it is easy to disassemble during maintenance. The disadvantage is that there are too many external connections, and the lack of protection will cause leakage hazards. At the same time, this type of structure basically does not have short-circuit protection devices and high-voltage output control devices. risk
[0005] It can be seen that the existing battery box structure has safety risks and inconvenience in maintenance

Abstract

The invention discloses a battery box and an electric automobile using the battery box. The battery box comprises a box body, a battery module and an on-off controller, wherein at least one battery module is provided, and is mounted inside the box body; the on-off controller is mounted inside the box body in a pluggable way, and forms a serial battery circuit together with the battery module so as to perform on-off control on the serial battery circuit; the on-off controller performs on-off control on the serial circuit through an external signal and a manual emergency stop switch. Compared with the conventional battery box, the battery box can protect people from the risk of direct contact with high voltage, and when the on-off controller breaks down, the on-off controller is drawn out of the battery box only, without needing to detach the whole battery box, so that the convenience and the safety of battery box maintenance are improved. The electric automobile using the battery box is more flexible and convenient to maintain because the battery box maintenance is not limited by the space of the automobile body.

Description

technical field [0001] The invention relates to the field of battery protection control, in particular to a detachable battery box with an on-off protection circuit and an electric vehicle using the battery box. Background technique [0002] At present, battery boxes, especially battery boxes used in electric vehicles, are generally divided into two structural forms. [0003] One structural form is to place all battery modules and control devices in a box structure, which contains components such as fuses and contactors. This structure can realize short-circuit protection and high-voltage output control. During maintenance, it is necessary to open the box as a whole, and then remove the components that need to be replaced or repaired. The advantage of this kind of box structure is that the internal circuit of the battery box is integrated in the battery box, avoiding too many external connections, and plays a good role in protecting the internal circuit, avoiding the occurr...
