An external electric vehicle battery thermal management system is described. An electric vehicle thermal system provides external coolant to an internal battery thermal system of an electric vehicle. The internal battery thermal system includes a liquid-to-liquid heat exchanger to cool or warm the set of batteries of the electric vehicle. The external coolant is pumped through a first side of the heat exchanger and serves as the source to cool or heat internal coolant pumped through a second side of the heat exchanger. The external coolant and the internal coolant do not mix.
