The invention discloses a firmware upgrading method, a firmware upgrading system, a vehicle-mounted charger and a storage medium, and relates to the technical field of new energy automobiles, and the firmware upgrading method comprises the following steps: receiving a firmware upgrading instruction issued by a diagnostic instrument through a communication module; according to the firmware upgrading instruction, an enabling signal is sent to a power module, so that the power module outputs power supply power; meanwhile, the firmware in the inactive unit is upgraded according to the firmware upgrading instruction, so that the power module in the firmware upgrading system can normally output power supply power to supply power to the load while the firmware in the vehicle-mounted power supply is upgraded through the inactive unit in the firmware upgrading system; in this way, the situation that the power supply cost is increased due to the fact that a microcontroller of the vehicle-mounted power supply cannot run an application program and the vehicle-mounted power supply cannot output power supply power to supply power to a load when the vehicle-mounted power supply is upgraded on a boot loader conventionally, and an extra power supply needs to be configured for power supply is avoided.

    本申请公开了一种固件升级方法、固件升级系统、车载充电机及存储介质,涉及新能源汽车技术领域,包括:通过通信模块接收诊断仪下发的固件升级指令;根据固件升级指令,向功率模块发送使能信号,使功率模块输出供电功率;同时,根据固件升级指令,对非激活单元中的固件进行升级,实现在通过固件升级系统中的非激活单元对车载电源中的固件进行升级的同时,固件升级系统中的功率模块能够正常输出供电功率为负载进行供电,以此避免了常规的在引导加载程序上进行车载电源的升级操作,而使得车载电源的微控制器无法运行应用程序,造成的车载电源无法输出供电功率为负载进行供电,而需额外配置供电源进行供电,造成的供电成本增加的情况。
