Battery cell temperature logic control method for air-cooled chiller unit

Abstract

The invention provides an air-cooled chiller unit cell temperature logic control method, and relates to the technical field of energy storage cell group temperature control, and the control method comprises the following steps: a chiller unit communicates with an upper computer to obtain the maximum temperature value Tmax, the minimum temperature value Tmin, the average temperature value Tavg and the average temperature heating starting point Theating of cells, and the maximum temperature value Tmax, the minimum temperature value Tmin, the average temperature value Tavg and the average temperature heating starting point Theating of the cells are obtained; according to the method, the running state of the water chilling unit needing to be operated is judged on the basis of comparison of the parameters including the average temperature return difference Tavg return difference, the temperature difference value T temperature difference, the temperature difference return difference T return difference, the average temperature limiting value T0, the minimum temperature limiting value T1, the maximum temperature limiting value T2 and the temperature difference limiting value T3, the air conditioner energy consumption can be effectively reduced, energy saving of an energy storage system is achieved to the maximum extent, and the energy saving efficiency is improved. The service life of the water chilling unit is prolonged.
