た。2. Description of the Related Art Conventionally, a device whose main power source is a battery is
There was a limit to the amount of energy that could be used, so there was a limit to its use. In particular, there was a problem at the end of the output capacity of the battery during use of the device. In many devices that do not measure the remaining capacity information, the output of the devices suddenly stops without a warning regarding the end of battery capacity. Also, as seen in JP-A-2-143181 having a battery residual capacity meter,
In advanced equipment, the remaining capacity meter was displayed in different colors at the end of the battery capacity, and a sound alarm was issued.

At the end. Also, if you want to give an alarm before the end,
In the case of only the warning by light, it may be ignored and the equipment may be stopped without additional energy supply. Even if the alarm is not reached, if the device is left with a small amount of energy stored in the battery, the remaining capacity of the battery may be terminated due to self-discharge of the battery. Especially when a large moving body such as an electric vehicle stops at the end of energy, it is often difficult to replenish energy. As described above, the conventional technique has a problem that the residual energy is suddenly terminated.

所まで走行し運行を中止できる。In the present invention, the energy of the battery is distinguished from the main part and the spare part, and when the main part is finished, the output of the device using the battery is temporarily stopped. In order to use the reserve part of the energy of the battery, a special switch for reuse must be connected, and the user strongly recognizes that the remaining amount is low. It has a remaining capacity meter to distinguish the energy in the battery, and when the remaining capacity falls below a certain standard, it is used as reserve energy. This ensures that the device is replenished with energy without stopping unexpectedly during use. In the case of an electric vehicle, there is a strong recognition of the remaining capacity of the energy, and at the time of recognition, a small amount of drive / driving can be performed with reserve energy, so the vehicle will not stop at a place where the battery cannot be charged during traveling, and You can drive to a place where you can recharge and stop operation.

の予備行動を行い、作業・走行に支障がない。If the control device suddenly stops the used device regardless of the intentions of the user and the driver, work is being performed, and in the case of an electric vehicle, the running state is disturbed. Therefore, a warning is given for a certain period before the stop. As a result, the user / driver performs preliminary actions for stopping in advance, and there is no hindrance to work / running.

業量の増大、電動車両での走行距離の伸長のためには放
電出力の減少が必要となる。In general, when the discharge output of a battery is increased, the power that can be taken out decreases. It is considered that this is due to an increase in internal resistance accompanying an increase in current. Therefore, it is necessary to reduce the discharge output in order to increase the work amount of the equipment used and extend the traveling distance of the electric vehicle.

となる。Particularly in a state where the reserve energy is used and the remaining capacity is small, when the output is extremely increased, the equipment used may stop. According to the present invention, by limiting the output in the reserve energy use region where the remaining capacity is small, the electric vehicle or the like can be easily moved to a rechargeable place.

FIG. 1 is a conceptual diagram of a control system of an electric scooter using the battery output control device of the present invention. A lead battery 101 has a voltage of 48 V and a capacity of 30 Ah when discharged at a rate of 5 hours. The battery capacity was measured by equipping the battery with the remaining capacity meter 102, and 25 Ah out of the total capacity was defined as the main energy and 5 Ah as the reserve energy. Electric power from the battery is input to the control circuit 103 and output to the electric motor 105 according to an instruction from the speed control mechanism 104 such as an accelerator.

ッチを入れることにより再び走行が可能となった。An urban driving test was conducted at a maximum speed of 30 km. When the main energy of 24Ah has been consumed due to the consumption of energy by running the scooter, the self-discharge of the battery, or the decrease of the battery capacity due to the change of the battery temperature, the warning device built in the remaining capacity meter gave a warning. . When 25 Ah was consumed, the output to the electric motor was stopped by the control circuit and the running was stopped. By turning on the reuse switch, it became possible to run again.

等の走行性能は劣ってしまった。A maximum current of 100 A flowed during acceleration until 25 Ah of main energy was consumed. Maximum current of 5 when using reserve energy with continuous reuse switch
The output was reduced and limited by limiting it to 0A. Due to this, 1.7 km / Ah when main energy is used
The mileage per energy was 2 km / Ah, and the mileage increased. Therefore, it became possible to move to a rechargeable place after a warning that the remaining capacity of the main energy had decreased. However, as a result of limiting the output, driving performance such as acceleration was inferior.

なくなる。Comparative Example In order to verify the effectiveness of the present invention, as a comparative example, a control device obtained by omitting the battery energy dividing mechanism from the battery control device of this embodiment was mounted on an electric scooter. Since the battery energy split mechanism was abolished, the reuse switch, the alarm device when the main energy decreased, and the output control mechanism when the reserve energy was used would naturally not work.
