The voltage value at both ends is as the first voltage value.
It is understood that the last time here refers in the first all breakers disconnects preceding at the time of point, away from
Time nearest at the time of point when being disconnected from the first breaker.
Preferably, determine that voltage measurement unit acquires the voltage value at the experiment branch both ends after the first breaker disconnects
Process as second voltage value is specially：
Determine voltage measurement unit collected experiment branch both ends after the first breaker disconnects the second preset time
Voltage value is as second voltage value.It is worth noting that, because after the disconnection of the first breaker, the voltage at experiment branch both ends can go out
It now rebounds namely a certain range of raising, in initial procedure upon opening, the voltage at experiment branch both ends is unstable
, therefore, generally by voltage measurement unit the first breaker disconnect the second preset time after collected experiment branch both ends
Voltage value as second voltage value.Here the second preset time be it is artificial determined according to actual conditions, the present invention
The concrete numerical value of second preset time is not limited particularly.
Step s105：The internal resistance of accumulation power supply is calculated according to the first voltage value, second voltage value and current value.
More specifically, the mistake of the internal resistance of accumulation power supply is calculated according to the first voltage value, second voltage value and current value
Journey is specially：
Calculate the difference that second voltage value subtracts the first voltage value；
The ratio of calculating difference and current value, ratio are the internal resistance of accumulation power supply.
