An electric drive system with heat management includes an electric drive unit coupled with a battery system and a power conversion system. An energy storage unit contains at least one phase change material and is configured to manage thermal energy. A cooling system is configured to exchange heat and has a fluid system extending through the drive unit, the battery system, the power conversion system, the energy storage unit, and the cooling system. The fluid system configured to collect heat from the drive unit, the battery system and the power conversion system; selectively expel the heat through the cooling system; selectively store the heat in the energy storage unit in the at least one phase change material; and selectively supply heat from the energy storage unit to the battery system.
