By connecting a power converter (DC-DC converter: Down frequency converter) 32, The voltage generated by the smoothing capacitor 36 can be converted into a voltage that is supplied to the electric equipment load of the electric vehicle. 12V lighter 90, By: A headlight 91 that is mounted on the front side of the electric motorcycle by the high-beam (high-beam) 91a and the low-beam (near-light) 91b can be selected by the switch 92, And a taillight 93 that is mounted on the rear of the electric two-wheeled vehicle. And a position lamp 94 disposed at a position near the headlight. a high beam (high beam) 91a or a low beam (near lamp) 91b constituting the headlight (91) of the lighter (90), When the main switch (110) is ON (ON), any one of them is constantly (continuously) lit. a light-emitting diode 95 connected in parallel with a high beam (highlight) 9 1 a of the headlight 9 1 , It is an indicator bulb that is lit in the gauge assembly 8 when a high beam (far light) is selected. Headlights 9 1, Compared with the tail light 93, because of the need for illumination, It is used to resist the larger (load). And, Since the smoothing capacitor 36 connected to the inverter circuit 350 of the driving portion (motor drive) 35, Through the power converter (DC-DC converter: The down converter (32) is connected to the lighter 90, So for the charge to be charged in the smoothing capacitor 36 the permeable power converter (DC-DC converter: The down converter (32) is discharged. at this time, The voltage supplied to the lighter 90, Because it is powered by a converter (DC-DC converter: The down converter (32) is stepped down from high voltage (72V) to low voltage (12V). Therefore, it is possible to use a general (common) -19-201043497 specification (fixed voltage 12V) lamp. M G U (control device) 3 4, It is a ΤΗ sensor (throttle opening sensor) 341 that inputs the throttle opening degree from the detection of the throttle opening.

Control to control the drive of the electric motor 50. then, The operation of the above discharge control device will be described. When the main switch 110 is turned "ON" and becomes the closed state shown in Fig. 5, The relay switch (switching means) 1 20 is turned on (0N), The current is caused by the path shown by the dotted line of the high voltage battery (main battery) 3 1 to 5 According to the power converter (DC-DC converter: Down frequency converter) 3 2 is supplied voltage, Perform the lighting of the lighter 90 for 1 2 V, Further, the electric motor 50 is made to be driven by the drive unit (driver) 35. For general electrical equipment machines 1 500, The voltage of 1 2 V is supplied from the low voltage battery (sub-battery) 3 0 through the main switch 1 10 . Make these machines work (lighting). When the start switch (not shown) is turned ON (ON) in this state, The electric motor 50 starts to move, Making the DC voltage from the high voltage battery (main battery) 31, The electric motor 50 is driven by the inverter circuit 350 to be converted into a three-phase AC voltage. at this time, The smoothing capacitor (storage hand -20 - 201043497) 36 is mainly charged by the absorption of the fluctuation of the power supply voltage connected to the input side of the inverter circuit 350. When the main switch 1 10 is turned off (OFF) and becomes the spear of the sixth figure, The relay switch (switching means) 120 becomes open! , From the high voltage battery (main battery) 31 through the power converter (converter: The down-converter 32 supplies power to the electric motor 50 of the overdrive unit (driver) 35 to the electric power of the lamp 90. And the charging toward the smoothing capacitor 36 side is blocked. 〇 and, The charge that is charged toward the smoothing capacitor 36, The path shown by the dotted line is transmitted through the power converter (DC-DC converter: Frequency) 3 2 towards the lighter (headlights 91, The tail light 9 3 and the position light side flow, The voltage that is stepped down is discharged by applying 9 〇 to the lamp 90. therefore, When walking on an electric vehicle, When the "main stop switch" switch 1010 is turned "on", when the "main switch is turned off (OFF)", when the charge of the capacitor 36 flows to the "light charge to the headlight" on the side of the lamp 90, When the discharge control device discharges "system", (1) Displaying the presence or absence of the output of the power converter (DC-DC converter) 32, "H/L of DownREG" (2) The general electrical equipment showing the output of the general electrical equipment 150 Output", (3) "Contactor action" indicating the status of the relay switch 120, (4) Display "system start or close" including the start state of the discharge control drive control device, It becomes as shown in Figure 7. That is, "the walking of the electric vehicle 1", Because the main switch 1: Open shape: OFF ) DC-DC ', And the frequency reduction of the shaded picture is 94) 90 when the lighter is on, the Lord , Smooth I H / L (system shutdown: Downstream output "Nothing" of the operating device 10 and following -21 - 201043497 The electrical switch (switching means) 120 is in the closed state. Therefore, "H/L output of DownREG" is "ON" (Yes) "State" "General electrical equipment output" is in the state of "ON" (Yes). When the relay switch (switching means) 120 is in the closed state, the "contactor operation" is in the "ON" state. "System start 0 Γ OFF" is in the startup state. When the "traveling stop" of the electric vehicle 1 is stopped, the above state can be maintained by stopping the electric motor 50. When the main switch 1 10 is OFF (OFF), the "main switch is off (0FF)" Because the voltage supply of 12V from the above state to the general electrical equipment machine 150 is blocked, Therefore, "general electrical equipment output" is in the state of "off (OFF)" (none). And the "contactor action" is in the "OFF" state. The relay switch (switching means) 12 is turned on, The voltage supply from the high voltage battery (main battery) 31 is blocked, However, since the electric charge from the smoothing capacitor 36 flows, "the electric charge is output to the H/L (headlight)", Therefore, the "H/L output of DownREG" is maintained in the "ON" state. When the system is turned off by the discharge control device and the discharge stored in the smoothing capacitor 36 is completed, "Output of H/L of DownREG", "General electrical equipment output", The "contactor action" is all turned off (OFF). The situation of the locomotive, In order to turn the lighter during walking during the day (headlights 9 1 , Taillight 93 and position light 94) 90 lights, When the main switch 1 10 is turned on (ON), the 1 2 V voltage is supplied. But according to the above structure, When the main opening -22- 201043497 is closed 1 1 〇 disconnected (OFF), The voltage supply from the high voltage battery (main battery) 31 is interrupted, However, the charge accumulated in the smoothing capacitor 36 is transmitted through the power converter (DC-DC converter: Down frequency converter) 3 2 flow so that 1 2 V voltage is supplied. In this case, When the smoothing capacitor 36 is discharged, Although for the headlights 91, The lighter 90 of the tail light 93 and the position light 94 causes current to flow. But headlights 9 1 Any of the tail light 93 or the position lamp 94 may have a current flowing 〇. And, Because the headlight 9 1 is included in the lighter 90 that flows in the discharge current. It is possible to use a load with a large load (a load that consumes a large amount of power), Therefore, the electric charge of the smoothing capacitor 36 can be discharged early. And in order to notify the driver of the electric vehicle of the state in which the lamp 90 of the headlight 9 1 or the like is discharged, An indicator (not shown) that lights up when the lamp 90 is discharged may be provided in the gauge unit 8 of the electric vehicle 1. By this, The driver can recognize: The lighting of the lamp 90 after the main switch 1 10 is turned off (OFF) is generated by the discharge.
