Accompanying drawing explanation
Fig. 1 is the battery system structure schematic diagram of separate redundancy each other described in the utility model.
Embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 1, be the battery system structure schematic diagram of separate redundancy each other described in the utility model.The battery system of separate redundancy each other described in the utility model, comprising: n+1 battery cell, battery balanced module 1, battery management module, powered battery module 2; Described battery cell comprises storage battery 3, connects the primary coil 4 of described storage battery 3 positive poles and negative pole, and the storage battery 3 of n+1 described battery cell is connected mutually; Described battery balanced module 1 comprises secondary coil 11, and described secondary coil 11 forms a high frequency transformer 5 jointly with the primary coil 4 of n+1 described battery cell, and described battery balanced module 1 connects the both positive and negative polarity of n+1 described storage battery 3 of mutually connecting; For the described powered battery module 2 to motor 6 output electric energy, connect n+1 the both positive and negative polarity of the described storage battery 3 of series connection and in parallel with described battery balanced module 1 mutually; Described battery management module comprise lay respectively at two normally-closed contact relays 7 at the anodal and negative pole place of storage battery 3 described in each, for monitoring the parameter monitoring device of storage battery 3 state parameters described in each and being connected storage battery 3 positive poles and negative pole place and the normally opened contact relay 8 in parallel with described primary coil 4 described in each.Particularly, described parameter monitoring device is voltmeter 9, and the tie point of described voltmeter 9 positive poles and described storage battery 3 positive poles is between described normally-closed contact relay 7 and described storage battery 3 positive poles, and the tie point of described voltmeter 9 negative poles and described storage battery 3 negative poles is between described normally-closed contact relay 7 and described storage battery 3 negative poles.
As shown in Figure 1, under normal operating conditions, except battery cell Um is as redundancy, its normally-closed contact relay 7 disconnects and normally opened contact relay 8 is closed connect outside, all the other n battery cell U1 to Un, outside the equal closure of its normally-closed contact relay 7 and normally opened contact relay 8 all disconnect, the battery cell U1 to Un of series connection output electric energy offers the power-equipment motor 6 of electric automobile, by voltmeter 9, observe, certain battery cell in battery cell U1 to Un (being assumed to be battery cell U2) break down or hydraulic performance decline to also poor than battery redundancy monomer Um performance time, the normally-closed contact relay 7 at the both positive and negative polarity place of the poorest battery cell U2 of performance can be opened, by normally opened contact relay 8 closures of connecting single batteries U2 both positive and negative polarity, to in its battery cell U2Cong supply line, isolate away thus, normally-closed contact relay 7 closures of the battery cell Um positive and negative end of redundancy and normally opened contact relay 8 disconnects simultaneously, be introduced in supply line, guarantee that total cell voltage changes little, meanwhile, battery balanced module 1 is started working, and total voltage is carried out to equilibrium, makes the voltage difference of each battery cell drop to minimum, with this, circulate, replace out one by one the poorest battery cell of performance, powered battery module 2 offers motor 6 by the electric energy in the storage battery 3 of the n of a series connection mutually described battery cell.
