Problems solved by technology
[0003] In the prior art, electric vehicles are powered by batteries. When the batteries are overheated under the influence of long-term charging and discharging or external environmental factors, if the power supply continues, it is easy to cause safety accidents; the charging port of traditional electric vehicles is Charged, when children or adults accidentally touch the charging port, it is easy to cause danger, and when the electric vehicle is charging, the wheels of the electric vehicle can still be rotated by controlling the handle, which has a large safety hazard

The embodiment of the invention discloses an electric vehicle protection circuit and an electric vehicle. The electric vehicle protection circuit comprises a power-on module, a temperature detection module, a power module, a charging control sub-module, a control module, an alarm module, a brake module and an isolation module; the temperature detection module is connected in series between the power module and the power-on module, and is disconnected when the temperature of the power module exceeds a preset temperature, so that the control module cannot receive an electric starting signal, and the rotation of a driving motor is stopped. Through the charging control sub-module and the isolation module, a charging port is not electrified when the power module is not charged, so that the safety performance of the electric vehicle is greatly improved. When the power module is charged, an anti-theft signal or a brake signal is pulled down to a low level through the isolation module, so that the control module controls the motor to be locked, and the purpose that the vehicle cannot be ridden in the charging process is achieved. Compared with the prior art, the technical scheme provided by the embodiment of the invention can greatly improve the safety performance of the electric vehicle.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of electric vehicle protection, in particular to an electric vehicle protection circuit and an electric vehicle. Background technique [0002] With the rapid development of traffic, electric vehicles are loved by more and more people, but the accidents caused by electric vehicles are also gradually paid attention to. [0003] In the prior art, electric vehicles are powered by batteries. When the batteries are overheated under the influence of long-term charging and discharging or external environmental factors, if the power supply continues, it is easy to cause safety accidents; the charging port of traditional electric vehicles is Charged, when children or adults accidentally touch the charging port, it is easy to cause danger, and when the electric vehicle is charging, the wheels of the electric vehicle can still be rotated by controlling the handle, which has a greater safety haz...
