The invention discloses a heat management system for a multi-heat-source direct-current energy storage device and a control method for, the heat management system comprises a first heat management loop, a second heat management loop, an air conditioner loop and a four-way valve, the second heat management loop and the air conditioner loop share a plate heat exchanger, and the four-way valve controls the first heat management loop to be switched between large circulation and self-circulation. Heat exchange between the first heat management loop, the second heat management loop and the air conditioner loop is realized through plate type heat exchange; interconnection and intercommunication of an energy storage battery on the direct current energy storage device and a DC conversion module heat management loop are achieved through a set of integrated water cooling loop, and the refrigeration power is improved by installing an air conditioning system. Then the direct-current energy storage device controller compre
