Introduction of GCED series Independent BTM System

With the development of electric bus, the battery has become an important component that determines the life of electric buses. The battery thermal management system (BTMS) is one of the key technologies for ensuring the safety and reliability of electric buses.

Optimises battery efficiency and life: Guchen GCED series Independent battery chiller can protect the electric bus battery from overheating. It can effectively reduce the temperature inside the battery, which ensures that the battery can work normally, effectively prolonging its service life. It also protects against cold temperatures, which can adversely affect performance and lifespan.

Product Advantages of Guchen GCED Series Battery Chiller

The BTMS also features an intelligent monitoring system that can detect abnormal situations such as overheating or overcharging as well as abnormal vehicle operation.
The system will not only protect the battery from overheating by regulating its temperature but also prevent any damage to the battery cells. This will allow it to reach its full potential and last longer than expected.
The BTMS is integrated with the control system of electric bus. The communication between the BTMS and other systems of electric buses is through CAN BUS protocol.

More Details of Guchen GCED Series Independent Battery Chiller

Guchen Battery Chiller Consists of:
The BTMS consists of several parts, including a sensor unit, a control unit and an air conditioner. The sensor unit detects temperature changes in each battery cell or group of cells and transmits data to the control unit. The control unit regulates cooling fan speed according to actual conditions so as to maintain a constant temperature inside each battery. These functions are realized by using multi-channel PID controllers that are used for thermal management systems in electric vehicle industry.
