The invention discloses a thermoelectric power generation equalizing charge device of a power battery pack. The device comprises a heat collection plate, a heat dissipation plate, a thermoelectric power generation unit, a thermoelectric power generation detection unit and a switch matrix unit. The heat collection plate is arranged in the power battery pack, and each single battery is arranged on one side of the heat collection plate; the heat dissipation plate is arranged on the outer side of the power battery pack, and the thermoelectric power generation unit is arranged between the heat collection plate and the heat dissipation plate; the switch matrix unit comprises a plurality of switches; one end of each switch is connected with the corresponding single battery, and the other end of each switch is connected with the output port of the thermoelectric power generation detection unit; the input port of the thermoelectric power generation detection unit is connected with the output port of the thermoelectric power generation unit; and a detection circuit and an isolation switch S are arranged between the input end and the output end of the thermoelectric power generation detectionunit. Low-grade heat energy in the battery pack is converted into electric energy. Balanced charging of backward single batteries is selectively achieved. The energy utilization rate is increased, and a balanced charging power supply does not need to be additionally provided.
