A kind of new forms of energy car of the present invention charges and stops guard method, and which comprises the following steps：
The first step, starts to continue to monitor the charging current of new forms of energy car；
Second step, when the charging current of monitoring is more than charge threshold, starts to carry out timing to present charge state；
3rd step, when timing time exceedes threshold values, then keeps present charge state persistently to charge new forms of energy car, and
Synchronous monitoring charging current；
4th step, when the charging current for monitoring is less than complete charge threshold values, starts again at and present charge state is entered
Row timing；
5th step, when timing time exceedes threshold values, automatically powers off, and stops charging new forms of energy car.
Wherein, the charging current threshold values of described second step is：Electric current is not less than 3A.
Wherein, the time threshold values in the 3rd described step is：Time is more than 2min.

Wherein, the method is applied to charging box on cable, charging pile and other chargers.
New forms of energy car disclosed by the invention charges and stops guard method, and beneficial effect compared to existing technologies is,
Which is by monitoring to charging current, and persistently carries out timing to the state of charging beginning and end, so as to ensureing to start to charge up and
Complete charge state is accurate, at the end of charging, is automatically stopped charging, protects power supply, prevent potential safety hazard.
Description of the drawings
Fig. 1 charges for new forms of energy car of the present invention and stops the FB(flow block) of guard method.
Specific embodiment
Below with reference to accompanying drawing, give further elaboration to the present invention.
Accompanying drawing 1 is referred to, in the present embodiment, new forms of energy car charging stops guard method and comprises the following steps：
The first step, starts to continue to monitor the charging current of new forms of energy car；When new forms of energy car and charging pile, or other power supplys connect
When logical preparation is charged, monitoring charging current is got started.
Second step, when the charging current of monitoring is more than charge threshold, starts to carry out timing to present charge state；This second
The charging current threshold values of step is：Electric current is not less than 3A.When the charging current for monitoring is more than or equal to 3A, can be tentatively true
Recognize, current vehicle is in charged state.
3rd step, when timing time exceedes threshold values, then keeps present charge state persistently to charge new forms of energy car, and
Synchronous monitoring charging current；Time threshold values in 3rd step is：Time is more than 2min, that is, monitor the electric current of current charging not
Less than 3A, and when continuing the time of this state more than 2min, then it has been confirmed that current new forms of energy car is in charged state, then
Normal charging condition is entered, is persistently charged.
4th step, when the charging current for monitoring is less than complete charge threshold values, starts again at and present charge state is entered
Row timing；The complete charge threshold values of the 4th step is：Electric current is less than 3A.When electric current is less than 3A, it can be determined that, fill with,
Need power-off.
5th step, when timing time exceedes threshold values, automatically powers off, and stops charging new forms of energy car.In sight in order to ensure
When will be filled with, fully battery being charged, when charging current tentatively being judged less than 3A, needs the lasting regular hour, so as to protect
Demonstrate,prove real expiring to fill.Time threshold values in 5th step is：Time is not less than 5min.
In the present embodiment, the method is used for motor bicycle, and the charging of electric automobile stops protection.It is mainly used on cable
Charging box, charging pile and other chargers.
It should be noted that above-mentioned current threshold or time threshold values are set according to current GB, do not changing this
The basis of the thinking of embodiment, it is also possible to which above-mentioned each threshold values is adjusted according to different application scene or standard.
Please the charging in the new forms of energy car refering to accompanying drawing 1 terminates the flow process framework of guard method；
First, new forms of energy car is started to charge up, alternating-current installation/AC installation output AC electricity, also, alternating-current installation/AC installation is continued to monitor and filled
Electric current；If charging current is more than when starting to charge up threshold values, the current charging interval is counted to be increased, and otherwise, continues timing time
Start to reduce.
Then, when lasting timing time is more than time threshold values, represents and normal charging condition is currently at, then carry out routine
Charge.
Then, in normal charge state, charging current is continued to monitor, when monitoring charging current less than complete charge
During threshold values, then it is again started up time counting；
When counting between when finished more than the end time threshold values for setting, then automatically power off, stop new forms of energy car is charged,
AC charging equipment stops exchange output.
The new forms of energy car charges and stops guard method, by monitoring to charging current, and persistently to charging beginning and end
State carry out timing, accurate with complete charge state so as to ensure to start to charge up, at the end of charging, be automatically stopped charging,
Protection power supply, prevents potential safety hazard.
The above, only presently preferred embodiments of the present invention, are not intended to limit embodiment of the present invention, and this area is general
Logical technical staff can be very easily carried out corresponding flexible or change according to central scope and the spirit of the present invention, therefore this
The protection domain of invention should be defined by the protection domain required by claims.
