Active cooling power calibrating method and system for energy storing unit

Abstract

The present application relates to heat management and control of new energy vehicle, particularly to an active cooling power calibrating method and system for energy storing unit. The application aims at resolving the problem that the existing active cooling power calibrating experiment for energy storing unit executed in a wind tunnel cabin, is inefficient and costly. The active cooling power calibrating method for energy storing unit of the present application mainly comprises the steps of: improving inlet temperature of the energy storing unit to a target temperature with a heating device; cooling the energy storing unit with a cooling system in a way of maintaining the inlet temperature at the target temperature; calibrating parameters of the cooling system when the inlet temperature is kept stable at the target temperature. When the inlet temperature of the energy storing unit is heated to the target temperature by the heating device and maintained at the target temperature by the cooling system, and the parameters of the cooling system are calibrated, the active cooling power calibrating experiment for energy storing unit executed in a wind tunnel cabin, can be substantially simulated, even completely replaced, thereby reducing development cost and enhancing development efficiency.
