During charging of the present utility model, driving protection circuit makes electric vehicle not allow to start when charging, and then makes whole
Car circuit is protected, and ensures the personal safety of rider.
[brief description]
Fig. 1 is the schematic diagram of driving protection circuit during the charging in this utility model embodiment.
[specific embodiment]
Inventor is it is considered that need driving protection circuit during a kind of charging so that electric vehicle does not allow out when charging
Dynamic, and then so that vehicle circuitry is protected, and ensure the personal safety of rider.Describe in detail by the following examples.
Shown in Figure 1, during the charging of the present embodiment, driving protection circuit is based on five foot relays 101.Five foot relays
87a foot position in 101 is normal-closed end, is connected with the ignition switch 102 of vehicle, and the electric machine controller 103 of vehicle and gear
Switch 104 is connected between 87a foot position and the ignition switch 102 of vehicle.87 foot positions in five foot relays 101 and the storage of vehicle
Often electricity 105 is connected battery.Phase is distinguished with the combination instrument 106 of vehicle and battery bag 107 in 30 foot positions in five foot relays 101
Even.85 foot positions in five foot relays 101 control output negative pole 108 to be connected with Vehicular charger.In five foot relays 101 86
Foot position controls output cathode 109 to be connected with Vehicular charger.It is more highly preferred to, also can 87 foot positions in five foot relays 101
And the accumulator of vehicle often electricity 105 between be in series with safety element 110, in the present embodiment adopt 5a safety element.
In implementing, in driving, 12v power supply introduces vehicle from five foot relay 101 normal-closed end 87a foot position, gives
Combination instrument 106 and battery bag assembly 107 are powered it is ensured that driving a vehicle normal.During Vehicular charging, 12v power supply is accessing vehicle-mounted charge
After device, (i.e. 85 foot positions and 86 foot positions are respectively connected to 12v Vehicular charger and control output negative pole 108 and Vehicular charger to control output
Positive pole 109), five foot relay 101 adhesive, combination instrument 106 and battery bag 107 supply 12v power supply by 87 foot positions；Motor simultaneously
Controller 103, driving switch 104, pedal etc. are in non-powered state, and vehicle cannot be walked, driving protection when realizing charging
Function.
Here description of the present utility model and application are all simply illustrative and exemplary, are not intended to this practicality is new
The scope of type limits in the above-described embodiments.The deformation of embodiments disclosed herein and change are entirely possible, for that
For a little those of ordinary skill in the art, the replacement of embodiment and equivalent various parts are all known.Art technology
