POWER SUPPLY SYSTEM, ELECTRIC VEHICLE PROVIDED WITH SAME, AND CONTROL METHOD OF POWER SUPPLY SYSTEM
摘要：
When it is determined by a determining portion (54) that the SOC of a first auxiliary power storage device (BB1) has reached a first lower limit value (TL), a switching control portion (56) generates a switching signal (SW) to switch from the first auxiliary power storage device (BB1) to the second auxiliary power storage device (BB2). A SOC estimating portion (52) measures the OCV for the first auxiliary power storage device (BB1), for which it has been determined that the SOC has reached the first lower limit value (TL) and has thus been disconnected, and estimates the SOC of that first auxiliary power storage device (BB1), based on that measured OCV. If the estimated SOC is higher than the first lower limit value (TL), after the SOC of the second auxiliary power storage device (BB2) has reached the first lower limit value (TL), the switching control portion (56) generates a switching signal (SW) to switch from the second auxiliary power storage device (BB2) to the first auxiliary storage device (BB1).
摘要（中）：

当确定部分（54）确定第一辅助蓄电装置（BB1）的SOC已达到第一下限值（TL）时，切换控制部分（56）产生切换信号（SW）至 从第一辅助蓄电装置（BB1）切换到第二辅助蓄电装置（BB2）。 SOC估计部（52）测定第一辅助蓄电装置（BB1）的OCV，对于该第一辅助蓄电装置，已经确定SOC已达到第一下限值（TL）并因此被断开，并且估计SOC 的第一辅助蓄电装置（BB1）。 如果估计的SOC高于第一下限值（TL），则在第二辅助蓄电装置（BB2）的SOC达到第一下限值（TL）之后，切换控制部（56）产生切换 信号（SW）从第二辅助蓄电装置（BB2）切换到第一辅助蓄电装置（BB1）。
