The introduction of controller in temperature sensor of DC charging pile
Dc charging pile temperature sensor controller is an important part of the charging pile, it is responsible for monitoring and adjusting the temperature during the charging process to ensure charging safety and efficiency. The following is a detailed introduction of its concept, role and working principle:
Main component
concept
Dc charging pile temperature sensor controller is a system used to monitor and control the temperature of charging pile during the charging process. It usually includes components such as temperature sensors, single chip computers (controllers), motors and fans. The system can intelligently adjust the operation of the fan according to the data provided by the temperature sensor to achieve the purpose of heat dissipation and energy saving.
Function
Temperature monitoring: The current temperature of the heat sink or charging gun head is collected by the temperature sensor, and the data is sent to the MCU.
Intelligent control: The single chip computer determines the output instructions to the motor according to the received temperature data, which includes turning on the fan, turning off the fan or adjusting the fan speed.
Energy saving: Through intelligent control of the operation of the fan, reduce energy waste, especially in the DC charging pile working mode, to avoid a lot of energy waste caused by the continuous operation of the fan.
Safety protection: When the temperature is detected to be too high, the controller can control the charging pile to stop the charging output or reduce the charging output current to protect the safety of charging equipment and electric vehicles.
Working principle
Temperature acquisition: Temperature sensors are installed at key points of the charging pile (such as heat sinks or charging gun heads) to monitor temperature changes in real time.
Data processing: The MCU receives the temperature data from the temperature sensor, and judges the current temperature state according to the preset threshold temperature and temperature interval.
Output instructions: According to the processing results of the MCU output corresponding instructions to the motor, these instructions include open instructions, close instructions and adjustment instructions.
Fan control: The motor controls the operation of the fan according to the received instructions, and the fan adjusts the speed according to the voltage applied by the motor, thereby cooling the heat sink.
Differential calculation: In some systems, two temperature sensors are used to detect the temperature of the positive and negative electrodes of the charging gun head, and the temperature difference is obtained through differential calculation, and the controller controls whether to charge according to the temperature difference.
Through this intelligent temperature control mechanism, the DC charging pile can improve the safety and energy saving effect while ensuring the charging efficiency.
DC CHARGING PIlE SERIES
DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
