Problems solved by technology
[0003] At present, when a new energy vehicle fails and needs to turn off the power (turn on the battery switch), the vehicle control module usually sends a vehicle status signal to the control module in the BMS, and the control module makes a logical judgment and then sends a control signal to the battery switch , this process takes a long time, often the car or power supply has caught fire due to a fault, and the battery has not been turned off, which can easily cause the battery to explode, which is very dangerous

Embodiment Construction
[0034] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0035] New energy vehicles have incomparable advantages such as low energy consumption and light pollution, which can improve problems such as energy shortage and environmental pollution. As a strategic emerging industry in my country, new energy vehicles have received great attention in their research and development. With the strong support of our country, outstanding achievements have been made.
[0036] However, in the process of development, the "fire" of new energy is also constant. The power battery needs to be man...

The invention provides a new energy automobile battery protection device and method, and relates to the technical field of automobile battery control. The device comprises a level conversion module, acontrol module and a switch control module, the level conversion module is connected with a whole automobile control module and the switch control module, the control module is connected with the whole automobile control module, a battery and the switch control module, and the switch control module is connected with a battery switch. The level conversion module is used for receiving a whole vehicle state signal sent by the whole vehicle control module and sending the whole vehicle state signal to the switch control module; the control module is used for collecting a battery signal sent by thebattery, diagnosing the battery signal to obtain a battery state signal, and sending the battery state signal to the switch control module; the switch control module is used for sending a switch control signal to the battery switch according to the vehicle state signal and the battery state signal so as to control on and off of the battery. When the whole vehicle breaks down, a battery switch canbe rapidly controlled, and battery safety is ensured.
Description
technical field [0001] The invention relates to the technical field of automobile battery control, in particular to a new energy automobile battery protection device and method. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power fuels. They are welcomed by people because of their low-carbon and environmental protection. The BMS system is an important system for managing batteries in new energy vehicle systems. [0003] At present, when a new energy vehicle fails and needs to turn off the power (turn on the battery switch), the vehicle control module usually sends a vehicle status signal to the control module in the BMS, and the control module makes a logical judgment and then sends a control signal to the battery switch , This process takes a long time, often the car or power supply has caught fire due to a fault, and the battery has not been turned off, which can easily cause the battery to explode, which is v...
