This application provides an energy storage system and a power supply system. The energy storage system includes a battery pack, a power conversion component, a first liquid runner, a second liquid runner, a first drive apparatus, a second drive apparatus, and a liquid dispenser. The first liquid runner is in contact with the battery pack in a thermally conductive manner, and the first drive apparatus communicates with the first liquid runner. The second liquid runner is in contact with the power conversion component in a thermally conductive manner, and the second drive apparatus communicates with the second liquid runner. The liquid dispenser separately communicates with the first liquid runner and the second liquid runner. When the liquid dispenser is in a first working state, the first liquid runner is isolated from the second liquid runner. Control may be separately performed according to temperature requirements of the battery pack and the power conversion component. When the liquid dispenser is in a second working state, the first liquid runner communicates with the second liquid runner, to form one whole loop. In this way, the battery pack is heated by using heat generated by the power conversion component. A temperature control solution can be adjusted based on a working state, to reduce space occupied by the energy storage system and reduce power consumption.
