Abstract

The invention discloses a control and fault diagnosing system of a battery heater. The control and fault diagnosing system comprises a battery temperature detecting circuit, a control circuit, a main power circuit, a fault detecting circuit and a fault detecting enabling circuit. The battery temperature detecting circuit is used for detecting the temperature of a storage battery and converting the temperature into corresponding detecting voltage. The control circuit is used for comparing the detecting voltage with reference voltage and controlling the heater of the main power circuit to turn on or turn off according to the comparison result. The fault detecting circuit is used for detecting the faults of the heater of the main power circuit. The fault detecting enabling circuit is used for controlling the fault detecting circuit to connect according to the on and off conditions of the heater of the main power circuit. The control and fault diagnosing system has the advantages that the temperature of the storage battery can be detected and controlled effectively, the faults of the heater can be diagnosed, the reliability of the heater and the control device of the heater is increased, and the system is low in cost and high in sensitivity.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a battery heater control and fault diagnosis system. Background technique [0002] In the field of power supply, more and more occasions require the use of batteries, and the performance and life of batteries are closely related to their operating temperature. When the operating temperature is lower than a certain value, the discharge capacity and charging characteristics of the battery are significantly reduced. [0003] The negative electrode active material of the storage battery is fluffy lead particles. During the charge and discharge process, the dissolution and crystallization of lead play an important role in the electrode reaction process. The chemically active PbSO4 is a rhombohedral grain with a diameter of 10-5~10-3cm. If it is discharged at a low temperature, it is very easy to generate fine grains (with a particle diameter below 10-5cm). If the arrangement i...
