Embodiment Construction
[0039] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.
[0040] Such as figure 1 Shown is a structural block diagram of the electric vehicle collision high-voltage power-off protection system of the present invention, the protection system includes a collision sensor 1, an airbag controller 2, a vehicle controller 3, a battery pack 4, a battery pack management system 5, and a high-voltage contactor 7. The battery pack management system 5 is integrated inside the battery pack 4. The crash sensor 1 is connected to the vehicle controller 3 via the airbag controller 2. The battery pack management system 5 is connected to the vehicle controller 3 and the high-voltage contactor 7 respectively. Among them: the airbag controller 2 is used to receive the collision information of the electric vehicle collected by the collision sensor 1, and judge whether t...

The invention discloses an electric vehicle collision high-voltage power-off protection system, including an airbag controller, an impact sensor, a vehicle controller, a high-voltage contactor, a battery pack and a battery pack management system, wherein the battery pack management system is integrated inside the battery pack, the impact sensor is connected with the vehicle controller via the airbag controller, and the battery pack management system is respectively connected with the vehicle controller and the high-voltage contactor. The system not only can accurately deal with the misoperation, but also can solve the problem of battery leakage without collision or not meeting the condition of cutting off the high-voltage power supply, and at the same time, a wireless communication moduleis added to facilitate timely communication with the outside after cutting off the high-voltage power supply.
Description
technical field [0001] The invention relates to the field of electric vehicle battery safety protection, in particular to an electric vehicle collision high-voltage power-off protection system and a control method thereof. Background technique [0002] With the rapid development of society and economy, the energy issue has attracted more and more attention from all over the world. In the field of automobiles, in order to solve this problem, the country has begun to vigorously promote the development of electric vehicles. There is an essential difference between electric vehicles and traditional fuel vehicles. The battery voltage of fuel vehicles is 12V or 24V. Since it is within the safe voltage range, there is no harm to people and no special protection is required. The battery voltage of electric vehicles is usually between 300V and 400V. In order to save installation space, reduce vehicle weight, and extend the battery life of electric vehicles, the high voltage of many ...
