Description
Technical field
The present invention relates to intelligent charging spot charging technique field, in particular to a kind of intelligent charging stake safety protecting method
And system.
Background technique
New-energy electric vehicle refers to using vehicle power supply as power, with the vehicle of motor driven wheels travel.Due to new energy
For source electric car using electric power as power, effect on environment is small, and prospect is had an optimistic view of extensively, also complies with new energy strategic requirement.But
It is, namely because New-energy electric vehicle, using electric power as power, matched charging equipment, i.e. charging station and charging pile needs are matched
Set is kept up with, not so user's popularization inconvenient to use that will largely effect on New-energy electric vehicle.
Charging pile can be divided into alternating-current charging pile and two kinds of direct-current charging post.Alternating-current charging pile be mounted in electric car it is outer,
It is connect with AC network, provides the power supply unit of AC power source for electric automobile and vehicle-mounted charger；Direct-current charging post is fixed peace
It is connect outside electric car, with AC network, the power supply of DC power supply can be provided for off-board electric automobile power battery
Device.
Since the class of safety protection of charging pile is not high, it is easy to happen electric shock or core component is stolen equal danger.
Summary of the invention
In view of this, the present invention proposes a kind of intelligent charging stake safety protecting method that class of safety protection is not high and is
System.

The temperature control and protection unit further includes when being less than charging pile temperature alarming threshold value, and background server is according to adjacent
Temperature value judges whether temperature value variation is more than rate of rise in temperature threshold value in charging pile in charging pile in charging pile twice, super
In overcharge stake when rate of rise in temperature threshold value, background server controls charging pile and issues sound-light alarm, and reduces charging pile and fill
Electric current；When being less than rate of rise in temperature threshold value in charging pile, information recording unit is jumped to.
6. intelligent charging stake security protection system as claimed in claim 5, which is characterized in that
It is being more than charging pile safe charging current threshold and is being less than charging pile charging in the charging current control and protection unit
When current protection threshold value, background server controls charging pile and issues sound-light alarm, and reduces charging pile charging current and specifically also wrap
It includes:
Background server judges that receiving charging pile within the predetermined reception period reduces the execution feedback information of charging current, is connecing
It receives and continues charging when receiving in the period until terminating, when not receiving within the reception period, background server controls charging pile
Stop charging and jumps to information recording unit；
The temperature control and protection unit is being more than charging pile temperature alarming threshold value and when being less than charging pile temperature safety threshold value,
Background server controls charging pile and starts cooling device, and it is specific to reduce charging pile charging current further include:
Background server judges that charging pile is received within the predetermined reception period to be reduced charging current and start cooling device
Execution feedback information continues charging when receiving and receiving in the period up to end, when not receiving within the reception period, backstage
Server control charging pile stops charging and jumps to information recording unit.
