Fig. 6 gives the voltage detecting schematic diagram of charging system during the charging process, the battery management system BMS 6 of vehicle
By the voltage at detection test point 21, charging process is determined.Since battery management system BMS 6 detects the electricity at test point 21
The process of pressure is similar with the process of voltage at the BMS detection test point of vehicle when plugging charging plug manually in the prior art, this
Place repeats no more.
The principle of charging system of the invention are as follows: vehicle enters charge position, and vehicle issues signal and notifies that reversed pantograph is dynamic
Make, be automatically performed and connect with vehicle collector-shoe gear, then execute the configuration of shaking hands of charging system and vehicle automatically, is filled to realize
Electric process is automatically performed, and specific work process is as follows:
After new-energy automobile 9 drives into charged area, for driver by D grades of N grades of switchings, hand-braking, car speed is reduced to zero.Department
Machine presses rocker switch, passes through after 8 Rule of judgment of entire car controller (ECU) (ON fire, hand-braking, speed, gear are neutral gear)
Signal device 16 issues the switching signal that drop bow signal, 18 switching signal of monitoring device, instrument charge information are shown.Meanwhile it is whole
It is charged state that vehicle controller (ECU) 8, which controls vehicle, and locking vehicle can not start and travel.
When charging system connects, after pantograph 20 receives signal by signal device 17, triggering pantograph drives electric cylinders 22
Guide rod stretches out, and support 10 cutting mechanism of current collecting bow lifting device is stretched out, to make pantograph pole plate 3 by charging rack eminence rest position
It sets and moves to 4 top of vehicle collector-shoe gear, contacted with the pole plate 23 of collector-shoe gear 4.During the connection process, since electrode plate structure is
Plane pole plate form, while pantograph pole plate 3 and collector-shoe gear pole plate 23 are right-angled intersection contact form, can guarantee vehicle its
In the case where direction of advance and transverse direction certain error, the two can also contacted, establishes charging connection.Ground charging equipment
On pantograph 20 and the collector-shoe gear 4 on vehicle quadrupole (anode, cathode, the connection of the pole plate that both make by the above process
Confirmation pole, protective grounding pole) it contacts one by one respectively, to complete charging physical connection.
Pantograph 20, which executes drop bow movement, contacts pantograph pole plate 3 with the collector-shoe gear pole plate 23 of vehicle collector-shoe gear 4
When, monitoring display screen switches to the picture of monitoring device 18, and instrument shows charge information (voltage, electric current, remaining capacity SOC etc.
Information).After pantograph pole plate 3 is contacted with vehicle collector-shoe gear 4, battery management system BMS 6 reports entire car controller (ECU) 8
Drop bow is uncharged；And the report reversed pantograph of charger 1 is sent by CAN-PLC converter 2 and 5 period of PLC-CAN converter
It is had connected with collector-shoe gear.
After battery management system BMS 6 detects that test point 21 detects voltage, via CAN-PLC converter 2 and PLC-CAN
Converter 5 starts to charge communication, and parameter configuration carries out charging process automatically.
Charging terminates to be divided into two kinds of situations: the first situation, and battery 7 is full of automatically.Battery management system BMS6 transmission is filled
Electricity stops message, and charger 1 stops output charging, and after electric current to be charged is reduced to zero, the report drop of entire car controller (ECU) 8 bow is not
Charged state.After driver presses rocker switch, (rocker switch and the drop bow of BMS 6 are uncharged for 8 Rule of judgment of entire car controller (ECU)
State) switching that rising bow signal, 18 switching signal of monitoring device and instrument charge information are shown is issued by signal device 16 afterwards
Signal.Monitoring device 18 switches back into former monitored picture, and instrument shows prime information.Pantograph 20 receives signal by signal device 17
Afterwards, executing rising bow movement is detached from pantograph pole plate 3 and vehicle collector-shoe gear 4.Pantograph pole plate 3 rises and vehicle collector-shoe gear
After 4 are detached from, loss of voltage is detected at test point 21, battery management system BMS 6 reports that entire car controller (ECU) 8 rising bow is not filled
The state of electricity.At this moment, entire car controller (ECU) 8 control vehicle be can driving states, unlock, vehicle can normally start and
Traveling.
Second situation in charging process, needs to dispatch a car or the case where the needs such as other situations artificially stop charging manually
Under.Driver presses rocker switch, and entire car controller (ECU) 8 sends battery management system BMS 6 and stops charging instruction, battery management
System BMS 6 sends the charging of charger 1 and stops message after receiving, charger 1 stops output charging, and electric current to be charged is reduced to zero
Afterwards, report entire car controller (ECU) 8 drop bow uncharged state.Entire car controller (ECU) 8 Rule of judgment (rocker switch and BMS6
Drop bow uncharged state) rising bow signal, 18 switching signal of monitoring device and instrument charge information are issued by signal device 16 afterwards
The switching signal of display.Monitoring device 18 switches back into former monitored picture, and instrument shows prime information.Pantograph 20 passes through signal device
After 17 receive signal, executing rising bow movement is detached from pantograph pole plate 3 and vehicle collector-shoe gear 4.Pantograph pole plate 3 rises and vehicle
After collector-shoe gear 4 is detached from, test point 21 detects loss of voltage, and battery management system BMS6 reports entire car controller (ECU) 8 liters
Bend uncharged state.At this moment, entire car controller (ECU) 8 control vehicle be can driving states, unlock, vehicle can be normal
Starting and traveling.
Charging system of the invention is by three-phase dynamic electricity, using the reversed current collecting bow lifting of power drives, realize electric current from
Charger is able to solve new-energy automobile manual mode plug charging plug or other is inconvenient to the conveying of vehicles energy accumulating device
System carry out charging operation, there are problems that the high-voltage safety hidden danger of manual operation and increase cost of labor, improve new energy
The usage experience of source user vehicle；Current-carrying capability is promoted by the biggish contact area of pole plate, realizes 500A or more high current
Quick charge；Each pole plate does not contact between each other, realizes the mutually insulated between pole plates at different levels, avoids short circuit problem；And
It using pole plate planar structure and contact arranged in a crossed manner, solves butting error, driver is facilitated to stop.
