Energy storage type power supply module

Abstract

The invention discloses an energy storage type power supply module, comprising a module frame and an energy storage unit arranged in the module frame and insulated from the module frame, wherein the energy storage unit is formed by connecting multiple energy storage subunits in series, and two adjacent energy storage subunits are isolated by end separators to form a cooling air channel; and the module frame is composed of a base plate and side plates, and an air inlet is arranged in the position, corresponding to each cooling air channel, of the base plate. As the energy storage unit of the energy storage type power supply module disclosed in the invention is formed by connecting multiple energy storage subunits in series, a cooling air channel is formed by two adjacent energy storage subunits in the manner of separating through end separators, and air inlets corresponding to the cooling air channels are arranged in the base plate of the module frame, cold air entering from the air inlets can play the role of effectively cooling the energy storage subunits, accordingly, the energy storage unit is enabled to be operated in the proper temperature range all the time, and furthermore, the service life of the energy storage unit is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of energy storage power supply manufacturing, in particular to an energy storage power supply module suitable for modern trams. Background technique [0002] With the development of society, the concepts of energy saving, environmental protection and other urban traffic rail development continue to increase, and energy storage rail vehicles have emerged. The so-called energy storage rail vehicles refer to electric traction The charging can be completed quickly within tens of seconds of getting on and off the train, and one charge can ensure that the energy storage rail vehicle can run to the next station before charging. [0003] The on-board energy storage power supply of energy storage trams is generally divided into integral on-board energy storage power supply and split on-board energy storage power supply. The so-called integral on-board energy storage power supply adopts the form of integral energy sto...

Problems solved by technology

[0004] However, the structure of the single power module in the current split power supply is not reasonable enough, resulting in poor ventilation and heat dissipation of the overall power module, and the long-term operation of the energy storage unit in a high temperature environment will greatly reduce the life of the energy storage unit.
