知られていた。(Prior Art) In an electric vehicle, a motor is usually driven by current from a storage battery. The voltage of the storage battery can be kept relatively low in golf carts etc. due to the low running speed, but in order to drive on general roads, the electric motor needs to be made faster and more efficient.
Generally, a high voltage of 96V or higher is required. In order to prevent electric shock accidents during inspections of these electric vehicles, a safety device has been known that disconnects the main circuit when the hood of the electric vehicle is opened.

In conventional electric vehicles, which are equipped with a safety device that disconnects the main circuit when the bonnet is opened, the main circuit is disconnected when the safety device is activated. When carrying out inspections, it was necessary to disable the safety device. When the safety device is released, the high voltage of the storage battery is connected to various wiring inside the bonnet, which poses a problem in that there is a high possibility of electric shock during inspection.

The present invention is characterized by comprising a storage battery connection switching circuit in which a drive circuit is connected to the control storage battery based on a hood open state signal from a hood open/closed state detection device.

とする。Further, the present invention is characterized in that it includes a manual switch means for generating a signal that enables connection of the drive circuit to the drive storage battery regardless of the signal state of the bonnet opening/closing state detection device.
（実施例） 本発明の一実施例を図面に基づいて説明する。(Example) An embodiment of the present invention will be described based on the drawings.
第１図は本発明にかかる電気自動車の構成図である。１
は接続切り替え回路で、駆動回路５の電源を躯１ノ用蓄
電池９あるいは制御用蓄電池１０へ切り換えることがで
きる。駆動用蓄電池９の電圧は９６Ｖ、制御用蓄電池１
０の電圧は２４Ｖとなっている。７は充電器でスイッチ
ングレギュレータを用いて電気的に紀縁しながら駆動用
蓄電池から制御用蓄電池への充電を行うことができる。FIG. 1 is a block diagram of an electric vehicle according to the present invention. 1
is a connection switching circuit that can switch the power source of the drive circuit 5 to the storage battery 9 for the body 1 or the storage battery 10 for control. The voltage of the drive storage battery 9 is 96V, and the voltage of the control storage battery 1 is 96V.
The voltage of 0 is 24V. Reference numeral 7 denotes a charger that can charge the control storage battery from the drive storage battery while electrically discharging the battery using a switching regulator.
２はボンネット開閉状態検出装置でボンネットの開閉状
態により信号を制御回路８に送る。３は手動スイッチで
、ボンネットが閉められた状態では、遮断状態になるよ
うに、ボンネットと機械的に結合されている。Reference numeral 2 denotes a hood open/close state detection device which sends a signal to the control circuit 8 depending on the open/close state of the bonnet. Reference numeral 3 denotes a manual switch, which is mechanically connected to the bonnet so that it is in a cutoff state when the bonnet is closed.
本実施例の動作を説明すると、まず通常走行状態におい
ては、ボンネットが閉じられているため、ボンネット開
閉状態検出装置からは閉状態の信号が出ている。この時
、制御装置８は接続切り替え回路を駆動用蓄電池に接続
し、駆動回路５は電動機６を駆動する。電動機６の線間
電圧の最高値は駆動用蓄電池と同様の９６Ｖとなる。To explain the operation of this embodiment, first, in the normal running state, the bonnet is closed, so the bonnet open/closed state detection device outputs a signal indicating the closed state. At this time, the control device 8 connects the connection switching circuit to the drive storage battery, and the drive circuit 5 drives the electric motor 6. The maximum value of the line voltage of the electric motor 6 is 96V, which is the same as that of the drive storage battery.
次に点検時であるが、ボンネットが開けられるとボンネ
ット開閉状態検出装置２がらボンネット開状態信号が制
御装置８に送られる。制御装置８は、ボンネット開状態
信号が入ると接続切り替え回路１を制御用蓄電池１０に
接続する。従って本実施例では全ての配線において電位
差の最高値は２４Ｖとなり、駆動用蓄電池を駆動回路用
電源として用いた場合の電位差９６Ｖに比してはるかに
安全に点検、修理等の作業を行なうことができる。Next, during inspection, when the bonnet is opened, a bonnet open/close state detection device 2 sends a bonnet open state signal to the control device 8. The control device 8 connects the connection switching circuit 1 to the control storage battery 10 when the bonnet open state signal is received. Therefore, in this example, the maximum value of the potential difference in all wiring is 24V, which allows inspection and repair work to be performed much more safely than the potential difference of 96V when the drive storage battery is used as the power supply for the drive circuit. can.
しかも、電気自動車のタイヤを回転させた状態での確認
等も容易に行なうことが可能であるため完全な点検が行
える。電動機６の回転数は最高回転速度の約１／４に制
限されるが、はとんどの点検はこの状態で行なうことが
可能である。Moreover, since it is possible to easily check the electric vehicle's tires while they are rotated, a complete inspection can be performed. Although the rotational speed of the electric motor 6 is limited to approximately 1/4 of the maximum rotational speed, most inspections can be performed in this state.
最高回転状態での点検が必要とされる場合のみ手動スイ
ッチ３を操作する。手動スイッチはボンネットと機械的
に結合されているため、点検開始時には常に遮断状態と
なっている。手動スイッチ３を投入すると、ボンネット
が開状態であっても、制御回路８はボンネット開閉状態
検出装置２の信号を無視し接続切り替え回路ｌを駆動用
蓄電池９に接続する。この状態で実際の走行時と同様の
最高回転状態での点検が可能となる。この場合において
も作業者は意識的に手動スイッチ３を操作することから
、作業者の安全意識の確認が行なわれ、しかも低電圧で
は既に電気自動車の安全が確認された状態であるため危
険性は従来の安全装置に比較して非常に小さくなる。Operate the manual switch 3 only when inspection at maximum rotation is required. Since the manual switch is mechanically connected to the bonnet, it is always in a cut-off state at the start of inspection. When the manual switch 3 is turned on, the control circuit 8 ignores the signal from the hood open/closed state detection device 2 and connects the connection switching circuit 1 to the drive storage battery 9 even if the bonnet is open. In this state, inspection can be performed at the highest rotational speed, similar to when the vehicle is actually running. Even in this case, the worker consciously operates the manual switch 3, so the safety awareness of the worker is confirmed, and since the safety of electric vehicles has already been confirmed at low voltage, there is no danger. It is extremely small compared to conventional safety devices.
