Charging pile tripping etc. non-responsive states when, car networking platform judge its be it is offline, accumulate offline time be car networking platform weight
Performance assessment criteria is wanted, but since TCU message accounting has been unable to complete its basic function in these malfunctions, caused practical offline
Time and system cumulative time grave fault, with the calculating of half an hour polling period, each failure longest error was up to 1 hour；D)
When bus loss of pressure, the power down simultaneously of TCU message accounting, maintenance personal cannot know and debug in time, also objectively increase
Accumulate offline time.It is existing when abnormal operating states such as the offline of the TCU message accounting of charging pile appearance, failure, crash
Technology is generally by power switch (contactor or the air in the erecting bed of charging pile to the TCU message accounting of charging pile
Switch) reboot operation is carried out, to restore the normal complete machine function of charging pile.
Have the remote reboot device by 4G signal communication in the prior art, can TCU message accounting to charging pile into
Row remote reboot, but because using 4G network communication, and charging pile is widely distributed, a large amount of charging piles are located at high-speed service area
Or the 4G communication apparatus such as outlying mountain area does not cover or covers poorly band, and this rebooting device is caused to cannot achieve corresponding control
Function.
In addition, charging station where charging pile may lose because of power supply buses main caused by by reasons such as bad weather, line maintenances
It presses and keeps whole station charging pile offline, after the recovery of main power supply buses voltage, should be configured in time in the car networking platform of charging pile
Offline charging pile is again online.If can shorten from main power supply buses voltage be restored to the offline charging of configuration it is again online when
Between be spaced, the whole usage experience of automobile user will be improved.
