Among them, the current sensor is used to monitor the current during charging to ensure that the current is within a safe range and prevent overloading; the voltage sensor is used to monitor the voltage during charging to ensure that the voltage is within a safe range and prevent overvoltage; the temperature sensor is used to monitor the temperature inside the charging pile to ensure that the charging pile works within a safe temperature range and prevent overheating; the access control sensor is used to monitor the state of the first front door 120, the second front door 121 and the side door 110 of the charging pile to ensure that all doors are closed during use to improve safety; the ground sensor is used to detect whether the electric vehicle is parked in front of the charging pile to ensure that the charging pile only provides charging service for the parked electric vehicle; the circuit breaker sensor is used to monitor the state of the line circuit breaker in the charging pile to ensure that the power supply can be cut off in time in case of failure to prevent safety accidents. The arrangement position and connection relationship of each sensor can be adjusted according to actual conditions, which will not be described here.

[0070] In addition, in combination with Figure 8 The switching power supply 800 is also arranged on the first front door 120 and / or the second front door 121, which is used to ensure that the charging pile can quickly cut off the power supply when needed, to prevent the charging pile from continuing to run in case of failure or abnormal condition, thereby avoiding possible danger and damage.
