Processing mode, the first processing mode are, after maximum voltage value is subtracted each other with minimum voltage value, then divided by the specified electricity
A reference value is pressed, to generate a voltage indexes value, such as the first voltage value is maximum voltage value, and the third voltage value is most
Small voltage value, then after the first voltage value and the third voltage value being subtracted each other, then divided by the rated voltage a reference value,
To generate the voltage indexes value, the first processor 16 judges the voltage indexes value pair according to one group of indication range information
The indication range answered, to generate a battery status information, in the first processing mode, described group of indication range information includes one
First indication range is that the voltage indexes value is less than 0.5% (voltage indexes value<0.5%) range, one second index model
Enclose be the voltage indexes value is 0.5% less than 1% (0.5%≤voltage indexes value<1%) range, a third refers to

0.995) range, a third indication range is that the voltage indexes value is more than 0.98 and 0.99 or less (0.98<Voltage indexes
Zhi≤0.99) range, a four-index range be the voltage indexes value be more than 0.96 and 0.98 or less (0.96<Voltage
Index value≤0.98) range and one the 5th indication range be the voltage indexes value be 0.96 or less (voltage indexes value≤
0.96) range.
The third processing mode is after being added the first voltage value, the second voltage value and the third voltage value
It is averaged to obtain an average voltage, and by the first voltage value, the second voltage value and the tertiary voltage
Value takes absolute value respectively after subtracting each other respectively with the average voltage, with one voltage calculated value of corresponding generation respectively, and according to
Each voltage calculated value access is worth maximum voltage calculated value and generates the voltage indexes value, and the first processor 16 is according to institute
It states group indication range information and judges the corresponding indication range of the voltage indexes value, to generate the battery status information, this reality
It applies in example, the indication range information corresponding to the third processing mode includes that one first indication range is the voltage indexes
Value is less than 25mV (milli Volt, millivolt, hereinafter referred to as mV) (voltage indexes value<Range 25mV), one second index model
Enclose be the voltage indexes value be 25mV less than 50mV (25mV≤voltage indexes value<Range, third 50mV) refers to
Mark range be the voltage indexes value be 50mV less than 100mV (50mV≤voltage indexes value<Range 100mV), one
Four-index range be the voltage indexes value be 100mV less than 200mV (100mV≤voltage indexes value<200mV)
Range and one the 5th indication range are the ranges that the voltage indexes value is 200mV or more (200mV≤voltage indexes value).
In the present embodiment, the battery pack is represented when the voltage indexes value falls then to generate in first indication range
Electric voltage equalization state is the battery status information of outstanding (Excellent), falls then to generate in second indication range and represents institute
The electric voltage equalization state for stating battery pack is the battery status information of good (Good), falls and then generates generation in the third indication range
The electric voltage equalization state of battery pack described in table is the battery status information of common (Usual), fall the four-index range then
The battery status information for generating the electric voltage equalization state poor (Not Good) for representing the battery pack, falls in the 5th index
Range then generates the battery status information for representing the electric voltage equalization state of the battery pack as very poor (Bad).
The first processor 16 controls first battery according to each voltage value, by the voltage control module 40
21, the charging of second battery 22 and the third battery 23 makes the battery pack slowly be restored to electric voltage equalization state, and
And the first processor 16 detects the battery pack and is believed with obtaining new battery status again when a detection time reaches
Breath then passes through when the first processor 16 is when a state duration of setting all generates identical battery status information
The battery status information is shown and is referred to for user by the display unit 17；In the present embodiment, the state duration
It can be at least 5 days, at least 7 days or at least 10 days, the state duration is only that citing is not in a limitative way, actually can root
