摘要： A controller for DC motor is provided with an FET (206) which is connected between one end of a motor (201) and the positive electrode of a battery EB, a diode (203) through which the electric current having flown through the motor (201) is passed when the switch (220) of the battery EB is turned off, a means for measuring the current flowing through the motor (201) which comprises a shunt resistor (203a), a differential amplifier (203b), and a low-pass filter (203c), and a controller (250) which PWM-controls the turn-on/off of the FET (206) so that the measured value of the current flowing through the motor (201) is coincident with a target value. The controller (250) sets a very small value as the target value when the switch (220) of the battery EB is turned off and supplies the very small current to the motor (201). Therefore, the FET which drives the motor of a bicycle with auxiliary motor is protected at a low cost without adding any extra component.

摘要： In step Sb3, the duty ratio calculated in step Sb2 based on feedback control is compared with the limit value of the duty ratio corresponding to the limit battery current. When the duty ratio is smaller than the limit value, the PWM wave corresponding to the duty ratio is outputted (step Sb4). When the duty ratio is larger than the limit value, the PWM wave of when the limit value is made the duty ratio, is outputted (step Sb5). Therefore, the duty ratio of the PWM wave generated as a current command does not exceed the limit value and no overcurrent exceeding the current limit value is fed from the battery. A large-capacity battery is not needed and the shortening of the cycle life of the battery due to overcurrent can be prevented.
摘要翻译：在步骤Sb3中，将基于反馈控制的步骤Sb2中计算的占空比与对应于极限电池电流的占空比的极限值进行比较。当占空比小于限制值时，输出与占空比对应的PWM波（步骤Sb4）。当占空比大于限制值时，输出限制值为占空比的PWM波（步骤Sb5）。因此，作为电流指令而产生的PWM波的占空比不超过极限值，并且从电池供给超过电流极限值的过电流。不需要大容量电池，并且可以防止由于过电流而使电池的循环寿命缩短。

摘要： After the depth of discharge of a battery which indicates the ratio of the discharge capacity of the battery to the nominal capacity of the battery is divided into a plurality of ranges and the number of charging times at which refresh discharge of the battery is to be executed is preset to each range, the depth of discharge is found by integrating the discharge capacity until the next charging time of the battery after the battery is once charged and repeating the integration of the counted number of charging times of a relevant range in accordance with the found depth of discharge at the time of charging the battery and, when the number of charging time of one of the ranges reaches the number of times at which the refresh discharge of the battery is to be executed, the refresh discharge is executed automatically of manually. Since the depth of discharge is divided into the ranges and the number of charging times at which the refresh discharge of the battery is to be executed is set, and then, the refresh discharge is executed when the number of charging times of one of the ranges reaches a set value, the refresh discharge can be executed automatically or manually at appropriate timing at which the effect of refresh discharge execution can be exerted most efficiently and the influence of the memory effect of the battery can be reduced effectively and efficiently.
摘要翻译：在指示电池的放电容量与电池的额定容量的比例的电池的放电深度被划分为多个范围和要执行电池的刷新放电的充电次数预先设定在每个范围内，通过将放电容量积分直到电池一次充电之后的电池的下一个充电时间为止，找出放电深度，并重复按照相应范围的计数的充电次数的积分在电池充电时发现放电深度，当其中一个范围的充电时间达到要执行电池刷新放电的次数时，手动自动执行刷新放电。由于放电深度被设定为要执行电池的刷新放电的充电时间的范围，所以在一个范围的充电次数达到设定值时，可以在可以最有效地发挥刷新放电执行效果的适当定时自动或手动执行刷新放电，并且可以有效且有效地降低电池的存储效应的影响。
