Two contacts of charge protection relay of the present invention are normally closed interlocks; one termination of charge protection relay is gone into the 48V power supply; the other end be installed in the key switch of putting on the device assembly and connect with lead, the coil input terminal of charge protection relay inserts the 220V general supply.
Compared with the prior art the present invention has the following advantages:
Compact conformation of the present invention, rationally; Because control system, charge protection relay, brake cut-off relay, key switch, cut-off switch, two-direction switch and accelerator are formed one group of control loop, can control the torque and the rotating speed of electronlmobil, can reach safety guard-safeguard again; Can guarantee that electronlmobil can not start when charging, eliminate safety hazard, play the safety guard-safeguard effect.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a charge protection frame principle figure of the present invention.
The specific embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
The present invention mainly by base plate 1, chopper, key switch 3, charge protection relay 4, control path wire fuse 5, total circuit wire fuse 6, retreat contactless switch 7, the contactless switch 8 that advances, main contactor 9, brake cut-off switch 10, brake cut-off relay 11, two-direction switch 12 and accelerator 13 etc. form.Employing on base plate 1 fixedly chopper 2, control path wire fuse 5, total circuit wire fuse 6, retreat contactless switch 7, the contactless switch 8 that advances, main contactor 9 form controllers.Charge protection relay 4, brake cut-off relay 11 are set on base plate 1, and connection puts to the key switch on the device assembly 3 with being installed in, be installed in cut-off switch 10 on the brake assembly on the anteposition plate, be installed in the two-direction switch 12 on the ahead and astern controlling device for electric automobile on the chaufeur dextral motor cover and the accelerator 13 that is installed on the anteposition plate forms one group of control loop and safety guard-safeguard.
Shown in the charge protection frame principle figure of the present invention:
The battery pack both positive and negative polarity adopts lead to connect with charger, and charger adopts lead to connect with charging socket; Charge protection relay one end and power supply (battery) 48V adopt lead to connect, the other end be installed in the key switch 3 usefulness leads of putting on the device assembly and connect, key switch 3 usefulness leads connect with the main power source contactless switch, and ground connection; Main power source contactless switch power supply is supplied with by battery pack, and offers controller.
It is 48V that one end of the B+ symbol on the controller of the present invention on total circuit wire fuse 6 connects, and it is the lead of battery pack negative pole end that the lead of the battery pack positive terminal of 200 (Ah), chopper 2B-symbol connect, the power connection of input controller.A1 on the chopper 2 connects with lead with stator coil on the series electric motor, and the contactless switch 7 binding post A2 that retreat that are fixed on the base plate 1 connect with lead with the series electric motor stator coil, makes magnetic steel of stator produce magnetic field after the energising.Be installed in contactless switch 8 post D 1 of advancing on the base plate 1, connect with lead with the rotor winding binding post on the series electric motor, two-direction switch 12 pulls out to suitable gear, contactless switch 8 energized of advancing, this moment the electronlmobil ahead running, contactless switch 7 post D 2 that retreat that are installed on the base plate 1 connect with lead with rotor winding binding post on the series electric motor, two-direction switch 12 is to the position of reversing gear, retreat contactless switch 7 energized, electronlmobil moves backward.When the electronlmobil glancing impact, the BK Brake Switch 10 that is installed on the brake assembly is connected, the coil working of control brake cut-off relay 11, the control system that one side 48V power supply enters chopper 2, impel the 48V power supply to open in system outage, electronlmobil can not move, and 12V power supply energising on the other hand makes stop, tail and number plate light bright.The control power supply input that be installed in the key switch 3 put on the device assembly and main contactor 9, the contactless switch 8 that advances, retreats contactless switch 7, chopper 2 connects with lead, controls the connection and the disconnection of power supply.
Charge protection of the present invention is to have the charge protection relay 4 that is contained on the base plate 1 to finish; 4 two contacts of charge protection relay are normally closed interlocks; the 48V power lead connects with an end of charge protection relay 4; the other end be installed in the key switch 3 usefulness leads of putting on the device assembly and connect; the coil input terminal of charge protection relay 4 inserts the 220V general supply; when the 220V general supply is inserted the charger socket; charger begins charging; while charge protection relay 4 coil workings; impel two contact opens; total system outage this moment guarantees that electronlmobil can not start, and plays the safety guard-safeguard effect when charging.
