  "textContent": "This application provides an energy storage device and a photovoltaic energy storage system. The energy storage device includes a heat management module, a battery module, a first power unit, a second power unit, and a radiator module. The heat management module includes a housing, and a multi-way valve, a first evaporator, and a condenser that are disposed in the housing. The housing includes a plurality of first interfaces. Two coolant ports of the first evaporator are connected to the multi-way valve, and two coolant ports of the condenser are connected between the multi-way valve and one of the first interfaces. The battery module includes a battery heat exchange plate, the first power unit includes a first power circuit heat exchange plate, the second power unit includes a second power circuit heat exchange plate, and the radiator module includes a radiator. The battery heat exchange plate, the first power circuit heat exchange plate, the second power circuit heat exchange plate, and the radiator are connected to the multi-way valve through corresponding first interfaces respectively. The energy storage device can efficiently adjust and control temperatures of a battery and the two power circuit heat exchange plates.",
