The protection measures for new energy charging piles mainly include the following aspects:
Technical protection: Intelligent identification technology is used to ensure that only matching electric vehicles can use the charging piles to avoid non-electric vehicles occupying the charging piles. At the same time, charging time limits and power limits are set to prevent a car from occupying the charging pile for a long time or overcharging.
Safety protection: Overcurrent protection: When the charging current exceeds the set safety value, the charging pile will automatically cut off the current to prevent excessive current from damaging the battery and circuit of the electric vehicle .
Overvoltage protection: When the input voltage exceeds the rated voltage range of the charging pile, the charging pile will stop working to prevent excessive voltage from damaging the battery and internal circuit of the electric vehicle .
Leakage protection: Equipped with a leakage protection device, once leakage is detected, the charging pile will immediately cut off the power supply to ensure the personal safety of the user 2.
Lightning protection: Outdoor charging piles should be equipped with lightning protection devices to effectively introduce lightning into the earth to prevent lightning from damaging the charging pile and the electric vehicle being charged .
Installation and use specifications:
Installation environment: The charging pile should be installed in a well-ventilated, dry, non-flammable place, away from water and flammable gases.
Installation quality: Installation should be performed by professionals to ensure that the installation is firm, the wiring is correct, and the grounding is good.
Usage: When using the charging pile, the user should strictly follow the operating procedures to ensure that the electric vehicle is correctly connected to the charging pile to avoid safety accidents caused by improper connection.
Maintenance:
Cleaning and maintenance: Regularly clean the charging pile shell, charging gun, display screen and other components to keep the surface of the equipment clean. For outdoor charging piles, pay special attention to waterproof treatment to prevent rainwater from seeping into the equipment.
Line inspection: Regularly check whether the cable is damaged, aged or poorly connected, and ensure that the cable insulation layer is intact and there is no exposed wire.
Function inspection: Regularly perform charging tests, display screen checks and payment function checks to ensure that the charging pile functions normally.
Seasonal maintenance: Pay attention to heat dissipation and waterproof performance in summer, and check whether the insulation measures are in place in winter
