In above formula (2), F is the rated current of battery, and G is the running current of battery, and H is the first predetermined current threshold；
If detecting, the running current of battery is far smaller than the rated current of battery, illustrates that battery is in Underflow Status, therefore basis
Above formula (2) can be accurately obtained the practical Underflow Status of battery, further ensure the electrical stability and flexibility of battery.
Step S111: if battery is in Underflow Status, undercurrent warning information is issued.
If battery is not at Underflow Status, undercurrent warning information is not issued.
The present embodiment can carry out electric current of the battery in charge and discharge process accurately to detect and control response, to prevent
Only battery is chronically at Underflow Status, has greatly ensured the Supply Security of battery；And then battery can be specified always
Operating status；Wherein undercurrent warning information can indicate the stream information excessively of battery, and technical staff is according to undercurrent warning information for more
The Underflow Status of a battery carries out undercurrent control response, the precision of control it is high, it can be achieved that the Underflow Status for battery essence
Function is really detected and controlled, compatibility is stronger.
It should be noted that may also be arranged on step S103 before the settable step S103 of step S110 and step S111
Later；Therefore the battery management method in the present embodiment can be realized for the balanced power supply control of multiple batteries and undercurrent protection function
