Abstract
The embodiment of the invention provides a battery pack heating device and control method for dual-car heating. According to the embodiment of the invention, the battery pack heating device is portably arranged at the exterior of a vehicle and comprises an energy storage device, a current sensor, a first diode, a first heating interface, a first switching device, a second diode, a second heating interface, a second switching device, and a heating control module; an input end of the first diode is connected with a second end of the current sensor; the first switching device is connected betweenthe second end of the current sensor and a positive pole of the first heating interface; an output end of the second diode is connected with the second end of the current sensor; the second switchingdevice is connected between the second end of the current sensor and a negative pole of the second heating interface; and the heating control module is used for controlling the opening and closing states of the first switching device and the second switching device. Therefore, the technical scheme provided by the embodiment of the invention can solve the problem that the single vehicle indirect heating mode can only heat one vehicle and is relatively low in heating efficiency in the prior art.
Description
【Technical field】 [0001] The invention relates to the technical field of batteries, in particular to a battery pack heating device and control method for heating two vehicles. 【Background technique】 [0002] Electric vehicles are one of the important directions for the development of China's auto industry, and they are also the hottest focus in the current auto industry. The biggest difference between electric vehicles and traditional vehicles is that the power of electric vehicles comes from the on-board battery pack, but the performance of the on-board battery pack is largely limited by the ambient temperature. Research data show that in an environment of minus 30 degrees, The charging and discharging performance of the on-board battery pack is basically zero, so it is very important to study the on-board battery pack to improve the adaptability of electric vehicles to the environment. Based on the phenomenon that the current low temperature environment has a great influe...
