摘要： A wheelchair T is driven by hybrid control of a fuel cell 3 and a rechargeable battery 5. The wheelchair is driven by a motor M to which electric power is supplied from the fuel cell 3 and the rechargeable battery 5. Electric power is supplied to the motor by hydraulic control based on load fluctuations corresponding to the travel conditions of the wheelchair T. The electric energy generated by the fuel cell 3 is kept at a constant level, and the energy of the lithium-ion battery 5 is additionally used when a high load is applied to the motor such as when the wheelchair is ascending a slope. When excess energy is generated by the fuel cell 3, the lithium-ion battery 5 is charged with the excess energy, thereby minimizing the possibility of exhaustion of the lithium-ion battery 5 so that the wheelchair can travel a long distance. By using a rechargeable battery that is resistant to load fluctuations, the wheelchair can be driven smoothly. By keeping the output of the fuel cell to a constant level, it is possible to prolong its life span. By charging the rechargeable battery with constant electric energy, the load on the rechargeable battery during charging is small, so that the life span of the rechargeable battery can be prolonged too.
摘要翻译：轮椅T由燃料电池3和可充电电池5的混合控制驱动。轮椅由电动机M驱动，电动机M从燃料电池3和可充电电池5供给电力。通过基于与轮椅T的行驶条件相对应的负载波动的液压控制将电力供给到电动机。由燃料电池3产生的电能保持在一定水平，并且锂离子电池5的能量当向轮胎施加高负载时，例如当轮椅上升斜坡时，另外使用。当燃料电池3产生多余的能量时，锂离子电池5被充满能量，从而使得锂离子电池5耗尽的可能性最小化，使得轮椅能够长距离行驶。通过使用耐负载波动的可充电电池，可以平稳地驱动轮椅。通过将燃料电池的输出保持在一定水平，可延长其使用寿命。通过以恒定的电能对可充电电池充电，充电期间充电电池的负载小，从而可以延长充电电池的使用寿命。
