Portable power supply

A portable power supply includes an internal power source, a thermal management system configured to control a temperature of one or more internal components of the portable power supply, a power input unit configured to charge the internal power source, a power output unit configured to provide power output by the internal power source, a first sensing circuit configured to detect a temperature of the one or more internal components, an auxiliary power source, and a controller. The controller is configured to receive a first signal from the first sensing circuit, enable the thermal management system based on a temperature of the one or more internal components, and enable charging of the internal power source based on the temperature of the one or more internal components. 一种便携式电力供应器包括内部电源、被配置为控制该便携式电力供应器的一个或多个内部部件的温度的热管理系统、被配置为对该内部电源进行充电的电力输入单元、被配置为提供由该内部电源输出的电力的电力输出单元、被配置为检测该一个或多个内部部件的温度的第一感测电路、辅助电源、以及控制器。该控制器被配置为从该第一感测电路接收第一信号，基于该一个或多个内部部件的温度来启用该热管理系统，以及基于该一个或多个内部部件的温度来实现对该内部电源的充电。
