Title
(EN) Battery pack voltage sampling circuit, method and system
(ZH) 电池组电压采样电路及方法、系统
Abstract
(EN)
The invention provides a battery pack voltage sampling circuit, method and system. The method comprises the following steps: detecting whether an air conditioner has a preset failure, wherein the preset failure comprises an air return probe failure, an exhaust temperature sensing packet failure, an evaporator outlet pipe temperature sensing packet failure, and evaporator inlet pipe temperature sensing packet failure; under the situation that the air conditioner has the preset failure, acquiring a historical operation record of the air conditioner, wherein the historical operation record is generated according to a preset rule under a normal working state; according to the preset failure and the historical operation record, determining a corresponding preset strategy; and according to preset strategy, controlling the air conditioner to run. According to the method, in the case of failure, the historical operation record generated when the air conditioner works normally is acquired; andaccording to the historical operation record and the preset failure, the corresponding preset strategy is automatically determined to emergently control the air conditioner, so that the technical problems of the prior art that the air conditioner cannot be automatically and accurately correspondingly and effectively controlled in the case of failure can be solved.
