Staggeredly engaged on direction.
One obvious advantage is that, especially from energy storage batteries extract high-frequency alternating current when can be significantly
Reduce loss of energy.Especially with integrated current transformer, the direct current transformer of so-called battery pack（“battery direct
inverter（The direct inverter of battery pack）,BDI”）Battery pack system in, the reduction of loss of energy is highly beneficial
, in order to which the change of Current Voltage quickly changed by what the electric current of battery module was conveyed in the battery pack system
Become.This to great extent by means of the power sense cell caused by low ohm internal electrode interconnection reduction and especially exist
Energy storage batteries it is extreme son on contact resistance reduction and may.
The plane contact of each electrode film and contact projection and battery pole terminal is particularly advantageous, this causes energy to be deposited
The Ohmic resistance of minimum within storage battery and the magnetizing force circular by the electric current within energy storage batteries minimized
Face.This can reduce vortex and be formed, and the therefore energy loss in the ac operation of reduction energy storage batteries.
Another advantage is, by minimizing the energy of energy storage batteries or prolonging for load output after load change
Late, the dynamic in short-term of such energy storage batteries is improved.It is possible thereby to advantageously abandon otherwise compensator that may be present
Part, such as buffer condenser, this can reduce the construction space demand of the component applied to energy storage batteries and be manufactured into
This.In addition, reducing avalanche energy by the improved dynamic of energy storage batteries, it is for by with such energy stores
For the energy storage module of battery is powered to BDI, it is meant that the smaller A.C.power loss in the switching device of the BDI.
Furthermore, it is possible to improve Electro Magnetic Compatibility by the perception for avoiding energy storage batteries loss component（EMV）, because
Launched electromagnetic field can be reduced and the interference effect to adjacent electronics component is reduced.In addition, reducing to the full extent for example
Due to ohmic loss caused by kelvin effect, this efficiency advantageously along with raising and less heat release.
