A hybrid has a lot more going on under the surface than a regular gas vehicle. Drivers usually think of the engine and the battery as separate components, but heat management is a key part of what makes the whole system work properly day after day. That is why hybrid cooling is not as simple as one radiator and one type of coolant doing every job. In hybrid vehicles, there is more than one cooling system working at the same time. Why Hybrids Need More Than One Way To Control Heat A hybrid vehicle has to manage heat from more than one major source. There is still an engine generating heat the way a traditional vehicle does, but there are electric components that generate heat as well, including the battery, inverter, and other electronics. Those parts do not all like the same temperatures, and they do not always need to be cooled in the same way. That is why hybrid vehicles end up with separate cooling systems. One part of the system may focus on the gasoline engine ... read more
