The introduction of DC charging pile overvoltage protection technology

Overvoltage protection of DC charging pile is an important function to ensure charging safety and stable operation of equipment. The following is a detailed introduction to DC charging pile overvoltage protection:

Main component

Concept:

Overvoltage protection refers to a safety protection mechanism that takes immediate measures to control voltage reduction or directly cut off the power supply when the power supply line voltage of the DC charging pile exceeds the predetermined maximum value to protect the charging pile and electric vehicles from damage.

Function:

1. Protection of charging equipment : Prevent excessive voltage from causing damage to the internal circuit of the charging pile to avoid equipment failure or damage.

2. Protection of electric vehicles : Avoid excessive voltage damage to the battery system of electric vehicles to ensure battery safety.

3. To prevent fire risk : Too high voltage may cause overheating of the charging line or equipment, increasing the risk of fire, overvoltage protection can effectively prevent this situation.

Working Principle:

Overvoltage protection is usually achieved in the following ways:

1. Voltage detection circuit : The voltage detection circuit on the main board of the charging pile can continuously monitor the input and output voltage. When the voltage is detected beyond the normal operating range, the control logic of the motherboard can react quickly, such as cutting off the charging circuit or issuing an alarm signal.

2. Protection devices : Common overvoltage protection devices include discharge tubes, diodes and varistors. These devices can quickly channel excess voltage into the ground when a sudden rise in voltage is detected, protecting equipment from damage.

3.Software control : The control software of the charging pile will execute the preset overvoltage protection procedure according to the feedback of the voltage detection circuit, such as disconnecting the charging contactor or reducing the output voltage.

Sum up

Through the above measures, the overvoltage protection function of the DC charging pile can ensure timely response in the case of abnormal voltage, ensuring the safety of the charging process and the reliability of the equipment.

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.
