Frequently Asked Questions
What is EV coolant?
EV (Electric Vehicle) coolant, also known as electric vehicle coolant or e-coolant, is a specialized fluid designed to regulate the temperature of electric vehicle batteries, motors, and other components. Unlike traditional engine coolant used in gasoline-powered vehicles, EV coolant is formulated to handle the unique thermal management requirements of electric vehicles. It typically has a lower boiling point, higher viscosity, and better thermal conductivity than conventional coolant, making it more effective at managing the heat generated by high-performance electric motors and batteries. (See: It Normal Coolant Leak)
How does EV coolant work?
EV coolant works by circulating through a closed-loop system, absorbing and transferring heat from the electric motor, battery, and other components to a radiator or heat exchanger. The coolant then releases the heat to the outside environment, allowing the vehicle’s components to operate within a safe temperature range. In some cases, EV coolant may also be used to cool the power electronics and other high-power components. The coolant’s effectiveness depends on its ability to manage heat transfer, viscosity, and boiling point, as well as its compatibility with the vehicle’s materials and components.
