Abstract

The invention relates to a battery power supply device, which comprises a left shell and a right shell. At least one battery pack is arranged on the internal side of the left shell. The battery pack consists of at least two monomer batteries which are serially connected. At least one battery pack is also correspondingly arranged on the internal side of the right shell. An air guide pipe is arranged on one side of the battery pack. A front finished circuit board and a rear finished circuit board are respectively arranged at the two ends of the battery pack. A front baffle is arranged on the external side of the front finished circuit board. A rear baffle is arranged on the external side of the rear finished circuit board. A negative terminal and a positive terminal penetrate through the front baffle or the rear baffle and then stretch out of the baffles. The battery power supply device has the advantages of compact structure, convenience in maintenance, good ventilation and heat dissipation performance and wide application scope.

Description

technical field [0001] The present invention relates to a battery power supply device. Background technique [0002] In the prior art, a battery power supply device usually firstly arranges a plurality of single batteries in series and in parallel in a bracket box including a housing and end plates at both ends, and then electrically connects the batteries in series. In the battery power supply device with the above structure, a plurality of single batteries are densely arranged in the bracket box, the electrical connection relationship between the batteries is complicated, and the positive and negative poles of the battery are easy to be installed reversely, which is easy to cause a short circuit, which brings great troubles to the assembly personnel. , the risk factor is high; at the same time, the battery power supply device with the above structure tends to generate a large amount of heat during charging and discharging, and the heat dissipation effect is poor. The safe...
