In one aspect, a thermal management system comprises a first coolant circuit (118) through which a first coolant is circulated, and the first coolant circuit (118) comprises at least: a radiator (138) for cooling the first coolant, a storage device (106) containing one or more power electronics, a heat exchanger (128), and a thermostatic valve (134) to output the first coolant to at least one of a storage device containing one or more power electronics and the heat exchanger. The thermal management system also includes a second coolant loop through which a second coolant is circulated, the second coolant loop including a heat exchanger configured to cool the second coolant using the first coolant, an energy storage unit (104) cooled by the second coolant, and a refrigeration unit (114) configured to cool the second coolant. A coolant temperature sensor (130) outputs a temperature of the coolant in the second coolant circuit, and a controller (158) controls at least the refrigeration unit based on the temperature of the coolant output by the coolant temperature sensor.
在一方面,热管理系统包括第一冷却剂回路(118),第一冷却剂通过第一冷却剂回路(118)进行循环,并且第一冷却剂回路(118)至少包括:用于冷却第一冷却剂的散热器(138)、包含一个或多个电力电子器件的储存装置(106)、热交换器(128),以及将第一冷却剂输出到包含一个或多个电力电子器件的储存装置和热交换器中的至少一者的恒温阀(134)。热管理系统还包括第二冷却剂回路,第二冷却剂通过第二冷却剂回路进行循环,第二冷却剂回路包括:被配置成使用第一冷却剂来冷却第二冷却剂的热交换器、由第二冷却剂冷却的储能单元(104),以及被配置成冷却第二冷却剂的制冷单元(114)。冷却剂温度传感器(130)输出第二冷却剂回路中的冷却剂的温度,并且控制器(158)基于冷却剂温度传感器输出的冷却剂的温度控制至少制冷单元。
