It is connected in turn with third accumulator Eq3, effectively supplements the decline of electricity in each accumulator, until storage capacitor C2 both end voltages
Drop to until being not enough to charge to accumulator, in the process, each accumulator both end voltage is stablized by storage capacitor C2, puts down
The output voltage of each accumulator of weighing avoids the voltage because of each accumulator to improve the electric discharge consistency of each accumulator
It is uneven and battery pack electric discharge is terminated in advance.After storage capacitor C2 electric discharge contacts, switch Sd is disconnected, certainly by accumulator
The electrical energy discharge of body carrys out the stabilization of Power Support system output voltage, in the process, continue control the first capacitance C1 in turn with
Each accumulator conducting, higher the first capacitance of the accumulator pair C1 chargings of both end voltage, the lower accumulator of both end voltage pass through
First capacitance C1 charges, and adjusts the electricity in two neighboring accumulator by the first capacitance C1 as a result, each to balance
The output voltage of accumulator avoids the Voltage unbalance because of each accumulator to improve the electric discharge consistency of each accumulator
And battery pack electric discharge is terminated in advance.
Meanwhile one side power supply passes through 100 rectification of the first rectification circuit, 200 inversion of inverter circuit and AC voltage-stabilizing circuit 2
After voltage stabilizing, the alternating current source that a stabilization can continue a journey is provided, is used in other equipment.On the other hand, if other are not configured
There is the computer of direct-flow input end, can be connect with AC voltage-stabilizing circuit 2 with ac input end and the second included rectification circuit 3,
By rectification, inversion, be computer power supply after rectification again.
And after alternating current is by 100 rectification of the first rectification circuit, 81 copped wave of the first DC chopper circuit, can directly be to calculate
The direct-flow input end of machine is powered, and inversion and again rectification link are eliminated, and reduces circuit energy consumption, improves battery pack cruising ability.
