Description
蓄電手段の劣化時には、蓄電手段の過充電、あるいは過放電の保護のため、電圧が最大電圧Ｖclimまたは最小電圧Ｖdlimに到達した場合に電流を減じることが一般に行われている。本実施例においても、劣化時のΔＶが閾値ΔＶthを超えた場合に、蓄電手段の充放電電流をあらかじめ設計されている電流閾値よりも小さくすることができる。また、図８に示すように、上限のＶclimから決定される電流閾値の場合、開始電圧を下げることで、電流閾値による許容範囲内の電流値を得ることが可能である。よって、走行中に電圧変動幅ΔＶが閾値ΔＶthに達し、ＶmaxがＶclimに達した場合には、ひとまず走行時の充電電流を減少させて走行する。走行終了後、次回走行開始時に、開始電圧を下げることにより、ＶmaxをＶclim以下とすることができ、電流値はもとの規定の電流値を得ることが可能となる。電圧変動幅ΔＶが閾値ΔＶthに達した時点で即座に蓄電手段を交換せずに、継続して蓄電手段を使用することが可能で、蓄電手段を有効利用できる制御が可能となる。尚、ΔＶがΔＶthに達し，かつ，最大電圧Ｖmaxが上限電圧Ｖclim、あるいは最小電圧Ｖminが下限電圧Ｖdlimに達した場合の電流制限は、ΔＶthに所定の回数達した場合に実施することも出来る。これによりノイズなどによる誤検知により無駄に電流制限を実施することを防ぐことができる。
When the power storage means deteriorates, the current is generally reduced when the voltage reaches the maximum voltage V clim or the minimum voltage V dlim in order to protect the power storage means from being overcharged or overdischarged. Also in the present embodiment, when ΔV at the time of deterioration exceeds the threshold value ΔVth, the charge / discharge current of the power storage means can be made smaller than the current threshold value designed in advance. Also, as shown in FIG. 8, in the case of a current threshold value determined from the upper limit V clim, it is possible to obtain a current value within an allowable range by the current threshold value by lowering the start voltage. Therefore, when the voltage fluctuation width ΔV reaches the threshold value ΔVth and Vmax reaches V clim during traveling, the vehicle travels while reducing the charging current during traveling. By reducing the start voltage at the start of the next run after the end of the run, Vmax can be made equal to or less than V clim, and the current value can be the original specified current value. When the voltage fluctuation width ΔV reaches the threshold value ΔVth, it is possible to continue using the power storage means without immediately replacing the power storage means, and it is possible to control the power storage means effectively. The current limit when ΔV reaches ΔVth and the maximum voltage Vmax reaches the upper limit voltage V clim or the minimum voltage Vmin reaches the lower limit voltage V dlim may be executed when ΔVth is reached a predetermined number of times. I can do it. As a result, it is possible to prevent wasteful current limitation due to erroneous detection due to noise or the like.
