In addition, since with respect to the phase inverter 350 bonded assembly smooth condensers 36 of drive division (motor driver) 35, via electric power converter (DC-DC conv: buck converter) 32 be connected with luminaire 90, therefore, for charging for the electric charge of smooth condenser 36, can be via electric power converter (DC-DC conv: 32 discharges buck converter).
At this moment, the voltage of supplying with to luminaire 90 utilizes electric power converter (DC-DC conv: buck converter) 32 be depressurized to low voltage (12V) from high potential (72V), therefore, can use the luminaire of normally used specification (rated voltage 12V).
MGU (control setup) 34 inputs are from the TH sensor (throttle valve opening sensor) 341 that detects throttle valve opening, the support sensor 342 of the jacking condition of inspection center's support 18, the control signal of the seat switch 343 whether identification of driver is taken, carry out the monitoring voltage of high potential storage battery (main storage battery) 31 etc., and, according to described TH sensor (throttle valve opening sensor) 341, the detected value of the motor rotary speed sensor 72 of electro-motor 50, carry out the energising control of the phase inverter 350 of drive division (motor driver) 35, thus the driving of control electro-motor 50.
The action of above-mentioned discharge control device then, is described.
When becoming closure state shown in Figure 5 when main switch 110 connections, relay switch (switching mechanism) 120 is connected, electric current from high potential storage battery (main storage battery) 31 along the path flow shown in the dotted line of Fig. 5, based on via electric power converter (DC-DC conv: 32 voltages of supplying with buck converter), light the luminaire 90 that 12V uses, and via drive division (motor driver) 35, electro-motor 50 becomes drivable state.Be equipped with 150 for common electrical installing, supply with the 12V voltages from low voltage storage battery (subsidiary battery) 30, make these equipment can work (lighting) via main switch 110.
Under this state, if fire switch (not shown) is connected, electro-motor 50 startings utilize phase inverter 350 to be converted to three-phase alternating voltage from the vdc of high potential storage battery (main storage battery) 31, thereby drive electro-motor 50.At this moment, electric charge is connected and to absorb smooth condenser (electric power storage mechanism) 36 chargings that power supply voltage variation is a main purpose to the input side with phase inverter 350.
When becoming off-state shown in Figure 6 when main switch 110 disconnections, relay switch (switching mechanism) 120 disconnects, block from high potential storage battery (main storage battery) 31 via electric power converter (DC-DC conv: buck converter) 32 supply with and supply with to the electric power of electro-motor 50 via drive division (motor driver) 35 to the electric power of luminaire 90, and, block charging to smooth condenser 36 sides.
And, charge in the electric charge of smooth condenser 36, along the path shown in the dotted line of Fig. 6, (the DC-DC conv: buck converter) 32 to luminaire 90 (head lamp 91, taillight 93 and position lamp 94) side flow via electric power converter, voltage after the step-down loads on luminaire 90, luminaire 90 is lighted, thereby discharged.
Therefore; under following situation; be that elec. vehicle is when " travelling "; when " travelling and stopping "; when main switch 110 is in off-state " main switch disconnection "; the electric charge of smooth condenser 36 is when " with the electric charge to H/L (head lamp) output " of luminaire 90 side flow; when finishing " system-down " of discharge based on discharge control device, (1) expression is from electric power converter (DC-DC conv: 32 output " output of the H/L of DownREG " that whether exists buck converter); (2) expression is installed " the common Denso output " whether 150 output fully exists to common electrical; (3) " the contactless switch action " of the running-active status of expression relay 120; (4) expression comprise discharge control device driving control device starting state " system starting or shut down " state as shown in Figure 7.
Promptly; because " in the travelling " of elec. vehicle 1; main switch 110 and relay switch (switching mechanism) 120 becomes closure state; therefore; " output of the H/L of DownREG " becomes the state of " ON " (having), and " common Denso output " becomes the state of " ON " (having), and relay switch (switching mechanism) 120 becomes closure state; so " contactless switch action " becomes the state of " ON ", " system's starting or shutdown " becomes the state of starting.
When " travel and stop " that elec. vehicle 1 stops to travel, electro-motor 50 stops and keeping above-mentioned state.
With main switch 110 open circuited " main switch disconnection " time, block 12V voltage from above-mentioned state and be equipped with 150 supply to the common electrical installing, therefore, " common Denso output " becomes the state of " OFF " (nothing), and, " contactless switch action " becomes the state of " OFF ", relay switch (switching mechanism) 120 becomes off-state, block from the voltage of high potential storage battery (main storage battery) 31 and supply with, but owing to become the state of flow of charge (electric charge is exported to H/L (head lamp)) from smooth condenser 36, so " output of the H/L of DownREG " keeps the state of " ON " (having).
When making " system-down " of the charge discharge end that is stored in smooth condenser 36 based on discharge control device, " output of the H/L of DownREG ", " common Denso output ", " contactless switch action " all become " OFF " state.
For two-wheeled, constitute when travelling by day, light in order to make luminaire (head lamp 91, taillight 93 and position lamp 94) 90, when connecting, main switch 110 supplies with 12V voltage, but according to said structure, when main switch 110 is disconnected, though the voltage supply from high potential storage battery (main storage battery) 31 is blocked, (the DC-DC conv: buck converter) 32 flow, thereby become the structure of supplying with 12V voltage but the electric charge that is stored in smooth condenser 36 is via electric power converter.
In this embodiment, when smooth condenser 36 discharges, for head lamp 91, taillight 93 and position lamp 94 these whole luminaires 90, electric current flows, and flows but also can constitute electric current any in head lamp 91, taillight 93 or position lamp 94.In addition, be contained in the luminaire 90 that discharge current flows by making head lamp 91, can the big resistance (load that consumption of current is big) of working load, therefore, the electric charge of smooth condenser 36 is discharged as early as possible.
In addition, for the chaufeur that makes elec. vehicle is known the situation of discharging at head lamp 91 luminaires such as grade 90, also can in the instrument pack 8 of elec. vehicle 1, be arranged on the indicator lamp of when luminaire 90 discharges, lighting (not shown).According to this structure, chaufeur can be discerned the lighting by discharge of luminaire 90 after main switch 110 disconnections caused.
