Why Thermal Management is Important in Electric Vehicles ? /
为什么热管理在电动汽车中很重要？
Need for Thermal Management System in EVs / 电动汽车对热管理系统的需求
❑Electric Vehicles have several requirements for an effective Thermal Management System / 电动汽车对有效的热管理系统有几个要求
▪Cooling Propulsion motors and other medium to high temperature  components / 冷却推进电机和其他中高温部件
▪Cooling electronics at a medium to low temperature / 中低温冷却电子设备
▪Cooling or Heating Batteries to a specific range (70F –90F) / 将电池冷却或加热到特定范围（70F–90F）
▪Cooling or Heating the Cabin and Occupants / 冷却或加热驾驶室和乘客
❑Electric Vehicles must address these needs and overcome some fundamental problems / 电动汽车必须满足这些需求并克服一些根本问题
▪Finite amount of energy on board for Heating and Cooling / 用于加热和制冷的能源有限
▪With no I.C. Engine, a much lower availability of waste heat / 在没有内燃机的情况下，废热的利用率要低得多
How T esla has addressed thermal management in Model Y ? /
特斯拉如何解决Model Y的热管理问题？
Tesla Model Y has chosen a new approach to address thermal management / 特斯拉Model Y选择了一种新的方法来解决热管理问题
❑Heat pump system for cabin heating & battery management / 热泵系统用于舱内加热和电池管理
❑Complex coolant circuit to enable multiple operational modes to use available waste heat and allow unique interface between coolant and  refrigerant systems / 复杂的冷却液回路，使多种操作模式能够利用可用的余热，并在冷却液和制冷剂系统之间建立独特的接口
❑Complex 1234-YF refrigerant heat pump circuit to allow multiple options for refrigerant flow to cabin and under hood heat exchangers / 复杂的1234-YF制冷剂热泵回路允许多种制冷剂流向座舱和发动机舱
盖下热交换器❑Indirect condensing and heat pump evaporation using single coolant heat exchanger(low temp radiator) to front end of vehicle (airstream) / 使利用单冷却液换热器（低温散热器）对车辆前端（气流）进行间接冷凝和热泵蒸发
