1. Overcurrent protection mechanism
Overcurrent protection is a circuit protection mechanism that detects and limits current exceeding a set threshold. When the current in the circuit exceeds a predetermined range, the overcurrent protection mechanism immediately takes action to prevent equipment damage or safety risks.
In the Charging Station system, the overcurrent protection mechanism is usually implemented in the following ways:
Current sensor: Use a current sensor to monitor the charging current in real time. When the current exceeds the preset safety threshold, the sensor sends a signal to the control system.
Control system: After receiving the signal from the current sensor, the control system immediately triggers the overcurrent protection mechanism. This may include measures such as cutting off the power supply, reducing the output current, or triggering an alarm.
Overcurrent protection device: Common overcurrent protection devices include fuses, circuit breakers, and electronic overcurrent protectors. These devices can respond quickly when the current exceeds the set threshold, cut off the circuit or limit the current, thereby protecting the safety of the equipment and users.
2. Overvoltage protection mechanism
Overvoltage protection refers to a protection method that takes measures to disconnect the power supply or reduce the voltage of the controlled device when the voltage exceeds the predetermined value.
In the Charging Station system, the overvoltage protection mechanism is usually implemented in the following ways:
Voltage monitoring circuit: The input voltage is monitored in real time through the voltage monitoring circuit. When the voltage exceeds the preset safety threshold, the monitoring circuit sends a signal to the control system.
Control system: After receiving the signal from the voltage monitoring circuit, the control system triggers the overvoltage protection mechanism. This may include measures such as cutting off the power supply, adjusting the output voltage, or triggering an alarm.
Overvoltage protection devices: Common overvoltage protection devices include varistors, lightning arresters, and overvoltage protection chips. These devices can respond quickly when the voltage exceeds the set threshold, reduce the voltage to a safe range or cut off the circuit, thereby protecting the safety of equipment and users.
3. Overheating protection mechanism
Overheating protection is a safety mechanism designed to prevent equipment or systems from being damaged or causing dangerous situations due to overheating.
In the Charging Station system, the overheating protection mechanism is usually implemented in the following ways:
Temperature sensor: Use a temperature sensor to monitor the temperature of the equipment and system in real time. When the temperature exceeds the preset safety threshold, the sensor sends a signal to the control system.
Control system: After receiving the signal from the temperature sensor, the control system triggers the overheating protection mechanism. This may include reducing output power, starting built-in cooling systems (such as fans, heat sinks, etc.), or triggering alarms.
Overheat protection devices: Common overheat protection devices include thermal relays, temperature switches, and overheat protectors. These devices can respond quickly when the temperature exceeds the set threshold, cutting off power or reducing output power, thereby protecting the safety of equipment and systems.
