Problems solved by technology
In a low temperature environment, the method of adding an insulating jacket is used to keep warm, and the effect is not ideal
The battery is often overheated or overcooled, its life is shortened or it cannot work normally, and fires and explosions occur from time to time. It cannot meet the basic requirements of automobile safety, reliability, and economy, and is a serious obstacle to the development of electric vehicles.
At the same time, the fault detection and alarm technology of the existing battery box temperature regulation system is not perfect

The invention provides a battery box system with the temperature automatically adjusted. The system comprises a cooling loop and a heating loop; a vehicle controller adjusts the temperature of a battery box through a low temperature controller and a high temperature controller according to the actual temperature of the battery box so that the temperature of the battery box can be kept within a settemperature range; meanwhile, the system monitors the working state of each component and reminds related personnel in time when an abnormality or fault occurs, so that it is guranateed that a battery pack, especially an electric vehicle lithium power battery pack, can work safely and reliably, and the service life of the battery pack can be prolonged.
Description
technical field [0001] The invention relates to a battery box system with automatic temperature adjustment, which is especially suitable for electric vehicles, boats, boats, boats and other special electric vehicles that require a power battery pack for power supply and require high reliability. Background technique [0002] Power battery boxes in the prior art (especially battery boxes for electric vehicle power lithium battery packs or nickel-metal hydride battery packs) all adopt natural or forced air cooling to regulate temperature. In a low temperature environment, the method of adding an insulating jacket is used to keep warm, and the effect is not ideal. The battery is often overheated or overcooled, its life is shortened or it cannot work normally, and fires and explosions occur from time to time. It cannot meet the basic requirements of automobile safety, reliability, and economy, and is a serious obstacle to the development of electric vehicles. At the same time, ...
