The invention belongs to the technical field of vehicle control, and discloses a battery heating control circuit, method and device, and the circuit comprises a VCU control module, a heating loop module comprising an MOSFET tube, and a charging loop module. The input end of the VCU control module is connected with the power module, the first output end of the VCU control module is connected with the input end of the MOSFET, the output end of the MOSFET is connected with the charging loop module, and the other end of the heating loop module is connected with the second output end of the VCU control module and the charging loop module. When the MOSFET tube is in a failure mode, the VCU control module can disconnect the power supply module. The heating loop module is controlled through the MOSFET tube, and meanwhile, the VCU control module is multiplexed, so that the heating loop can be disconnected in time under the condition of relay adhesion or overcurrent, the condition that the heating loop is difficult to disconnect is avoided, and the safety of the heating process is improved.
本申请车辆控制技术领域,公开了一种电池加热控制电路、方法及装置,该电路包括VCU控制模块、包括MOSFET管的加热回路模块以及充电回路模块;VCU控制模块的输入端与电源模块连接,VCU控制模块的第一输出端与MOSFET管的输入端连接,MOSFET管的输出端与充电回路模块连接,加热回路模块的另一端分别与VCU控制模块的第二输出端和充电回路模块连接;在MOSFET管为失效模式时,VCU控制模块可断开电源模块的连接。由于本申请通过MOSFET管控制加热回路模块,同时复用VCU控制模块,在继电器粘连或电流过流的情况下,可及时断开加热回路,避免了加热回路难以断开的情况,从而提升了加热过程的安全性。
