By buying and operation for many years, substantial amounts of different size, the battery of different vendor have accumulated.
The load variations of power department combination power network, will be divided into for daily 24 hours spike, peak, usually, low ebb etc. it is several
The individual period, different electricity price levels is formulated day part respectively, to encourage user's reasonable arrangement electricity consumption time, peak load shifting.One
As daytime be the peak of power consumption period, the electricity charge are higher；It it is at night the low power consumption stage, the electricity charge are relatively low.In the prior art can not be automatic
It is controlled according to discharge and recharge of the Peak-valley TOU power price to battery, may be in the electricity charge higher peak of power consumption period to battery
Group is charged, and causes running cost higher, adds the electric cost of user.
Operation and maintenance of the DC power-supply system to battery follows claimed below：
1st, the battery of more than 2 is configured in general batteries, is easy to the maintenance of safer batteries, simultaneously
Enough emergency service capacity can be ensured；
2nd, each battery is connected in parallel on DC master row in the prior art, and rectifier uses unified charge and discharge electrical specification pair
Battery carries out discharge and recharge, and the battery for causing different size can not be used in parallel.Each battery in same batteries

Harmful effect caused by flowing electric power system safe operation.
The battery requirement of DC power-supply system adds batteries maintenance work difficulty, needs in the prior art
Charge and discharge maintenance manually is carried out to batteries, is costly and inefficient.Made due to that can not be mixed by different size battery
Restriction so that a large amount of batteries for still having value can not make full use of the waste for causing resource：One side battery
Capacity can not meet change simultaneously during power equipment safety service requirement all with battery, to ensure power equipment not
It is interrupted safe operation, accumulator capacity dilatation is extremely restricted；The a large amount of different sizes of another aspect and also value
Battery is but idle, and causes resource serious waste.
