The invention relates to a power supply system, a vehicle, a method, a device and a storage medium. The power supply system is used for supplying power to the plurality of SOC chips and comprises an MCU chip and a plurality of PMIC chips, and each SOC chip in the plurality of SOC chips is connected with the MCU chip through at least one corresponding PMIC chip. The MCU chip is configured to write power-on parameters of a group of power rail signals corresponding to each SOC chip into a PMIC chip corresponding to each SOC chip when the MCU chip is powered on; the power-on parameters include a power-on timing and a voltage level for each power rail signal in the set of power rail signals. And each PMIC chip is configured to output a group of power rail signals with voltage levels to the connected corresponding SOC chip according to a power-on time sequence when receiving power-on parameters of the group of power rail signals from the MCU chip so as to supply power to the SOC chip. The system can realize proper power supply for a plurality of SOC chips.
本申请涉及一种电源供电系统、车辆、方法、装置和存储介质。电源供电系统用于向多个SOC芯片供电,包括MCU芯片以及多个PMIC芯片,多个SOC芯片中每个SOC芯片经由对应的至少一个PMIC芯片连接MCU芯片。MCU芯片配置为在上电时,将每个SOC芯片的对应的一组电源轨信号的上电参数写入每个SOC芯片的对应的一个PMIC芯片中;上电参数包括一组电源轨信号中每个电源轨信号的上电时序和电压电平。每个PMIC芯片配置为在从MCU芯片接收到一组电源轨信号的上电参数时,依照上电时序将具有电压电平的一组电源轨信号输出到所连接的对应的一个SOC芯片以向该SOC芯片供电。本系统能够实现对多个SOC芯片的适当供电。
