Cooling control method, cooling control device and cooling system of energy storage power supply

Abstract

The invention discloses a cooling control method of an energy storage power supply. The energy storage power supply is provided with a plurality of groups of fans, wherein each group of fans comprises a plurality of fans positioned at different parts. The cooling control method comprises the following steps: (1) detecting whether the energy storage power supply is in a charging state and entering the step (2) if yes; and (2) controlling first preset groups of fans to start. The cooling control method disclosed by the invention is capable of performing active cooling and radiating through analysis of temperature influence factors of the energy storage power supply and starting to cool the energy storage power supply when the temperature of the energy storage power supply is not raised, so that the rapid rise of the temperature in the energy storage power supply can be effectively avoided; meanwhile, the time of the energy storage power supply in a high-temperature environment can be effectively shortened and the service life of the energy storage power supply can be prolonged. The invention also discloses a cooling control device of the energy storage power supply capable of realizing the cooling control method and a cooling system of the energy storage power supply; the cooling system comprises the cooling control device, the fans and air cooling channels of the energy storage power supply.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicles, in particular to a cooling control method, a cooling control device and a cooling system for an energy storage power supply of a rail transit vehicle. Background technique [0002] Energy storage power supply is mainly used in energy storage rail transit vehicles. The so-called energy storage rail transit vehicles refer to modern trams that use supercapacitors to store electric energy, and use the passengers to get on and off the platform within tens of seconds to quickly complete Charging, one charge can ensure that the energy storage rail vehicle runs to the next station before charging. [0003] This is the first time that all supercapacitors are used as the sole power supply of modern trams. The power supply composed of supercapacitors realizes fast charging and discharging. Due to the short charging time, there will be a large charging current (600A-900A) during the charging pr...

Problems solved by technology

[0005] Although the cooling system of the energy storage power supply controls the temperature to a certain extent, because the cooling system is passively controlled, that is, the cooling fan will only be turned on when the temperature inside the energy storage power supply has risen to the upper threshold, which will prolong the use of the power supply. The time it takes for the internal temperature of the energy storage power supply to return to the normal temperature range makes the energy storage power supply in a high temperature environment for a long time, which affects the service life of the energy storage power supply
