The paper introduces the temperature protection of DC charging pile power switch chip

Main component

Concept:

Temperature protection refers to a safety mechanism integrated in the DC charging pile power switch chip to monitor and control the working temperature of the charging pile to prevent equipment damage or safety accidents caused by overheating. This technology typically involves temperature sensors and control logic to enable real-time temperature monitoring and automatic response.

Function:

1. Real-time monitoring: The temperature protection system can monitor the temperature change of the charging pile and its surrounding environment in real time to ensure that the charging process is carried out within a safe temperature range.

2. Automatic alarm and protection: When the temperature is detected to exceed the set safety threshold, the system can automatically trigger the alarm system, and even directly cut off the power supply to prevent safety accidents such as fire caused by overheating.

3. Improve safety: Through the temperature protection mechanism, the heat accumulation caused by poor contact and increased contact resistance at the connection of the charging plug can be avoided, reducing the risk of safety accidents.

Working Principle:

1. Temperature sensor: Install temperature sensors at key parts of the charging pile, such as charging plugs, charging cables, charging interfaces, etc. These sensors can monitor temperature changes in real time.

2. Signal conversion: The temperature sensor converts the temperature signal into a voltage signal and transmits it to the central control system.

3. Control logic: Control the motherboard to receive voltage signals, when the signal exceeds the preset value, send an overtemperature warning signal. The system can take measures to reduce the charging current or stop charging.

4. Alarm and cut-off: When the temperature exceeds the warning value, the system can send an alarm signal, and cut off the power supply when the temperature exceeds the alarm value to protect the safety of equipment and personnel.

5. Temperature monitoring and data analysis: Based on the data provided by the temperature chip, the charging pile can establish an intelligent temperature control system, automatically adjust the charging power, reduce the temperature, and ensure the safety of the charging process.

Sum up

In summary, the temperature protection function of the DC charging pile power switch chip is one of the key technologies to ensure charging safety, and through real-time monitoring and automatic response mechanism, it can effectively prevent equipment damage and safety accidents caused by overheating.

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.
