The cycling wave form control cycle of a Fig. 3 is that 13S (is t _a1～t _a9=9S; t _b1～t _b9=2.7S; t _b10=0.8S; t _cthe total of=0.5S), if with one group of nominal capacity 400AH, nominal voltage v ₂it is 561.65V400AH=224.64K that full scale electric weight is received in=480V lead-acid battery absolutization 100% storage va _mh calculates the loop control 13S71=923S of 71 Fig. 3 of 224.64/3.1826 ≈ (being roughly equal to 15.3min or 0.26H) can be full of electric weight by this Battery pack 100%, be v- v ₂=81.6V is the charge rate of extrapolating under fixed value condition.

The 0.21H charging core object of two-forty is: promote H _b: H _avalue (is called H by the charging stand-by period of same group storage battery _a; (electric discharge) time of use is called H _b; The H of same group storage battery _b: H _athe larger service efficiency of ratio is higher), shorten charging stand-by period H _a; Extend as much as possible H service time of battery _b, to bring into play its service efficiency, rapid charge needs ACDC to have enough A _moutput idle capacity supports, A _mmore can temper more greatly the vitality prolonging service life of battery of storage battery, A at a high speed _mneed to be in charging process from v ₂to RF, discharge accordingly-A _mjust can dredge out A _mfrom vflow to v ₂passage; Rapid charge need to carry out at the public charging station that possesses 2～6 conditions.

Low rate 5.1H charging core object is that storage battery 100% is full of to electric weight as much as possible, to prevent remaining electric weight spacing gradient and generate sulfuration crystal, nibble battery life, in order to reduce charging cost, from 3.923C, be reduced to its ACDC cost of 0.03923C and be only correspondingly lowered to 1%, small-sized ACDC couple input is also reduced to single-phase 220V alternating current can support A _mthe output current of=24A; Small-sized ACDC volume is also reduced to the Portable that no longer takies public place, to (the R in storage battery _Ω+ R _c+ R _e)≤0.034 Ω is also reduced to v- v ₂/ A _m=81.6V/24A=3.4 Ω; Accordingly from v ₂to RF, discharge |-A _m|=A _malso can be reduced to |-A _m| < A _m, can also take advantage of a situation and again take a step back thus, take and extend the longer charging interval and be charged into 44.928K as this storage battery va _mh discharges C < 2.64K in the time of amount in storage battery va _mh electric weight and constructing: with-A _mrF2 that extension drops into or the RF3 general-A in reduction and charging interval _mchange in the lower situation of renewable energy resources economic benefit then select RF1 work-A _mload 1; Adhere to take that 0.03923C speed is charged into 44.928K as this storage battery in 5.1H va _min the time of H, in storage battery, discharge C=2.64K va _mh electric weight; Be used in again input RF2 or RF3 general-A in 5.1H _mchange into the choice of 3 low speed charging scheme of the renewable energy resources.

Flexible A _m=( v- v ₂)/(R _Ω+ R _c+ R _e) need to be from charging process v ₂end is to RF release-A _mexcite R _Ω+ R _c+ R _eactive power vigorous (reduction resistance value) just can be dredged out A _mfrom ACDC's vend flows to v ₂passage v- v ₂, passage v- v ₂again by A _mfrom ACDC's vend flows to v ₂process in lifting in reverse direction v ₂=A _m(R _Ω+ R _c+ R _e) value compression is little v- v ₂voltage difference and block passage.R _Ω+ R _c+ R _ein only have R _Ωit is the pure physical resistance of fixed resistance value; Pure physical resistance resistance value in charging process remains unchanged, R _c+ R _ethe chemical polarization resistance of life entity attribute and the tandem compound body of bioactivation resistance; With pure Physical Thought, remove to find life entity R _Ω+ R _ein charging process, resistance value increases with the causality reducing against science; To find out R accurately _c+ R _ethe data of a series of numerous and complicated of the technique when causality of resistance value increase (active power glazes from vigorous) and resistance reduction (the vigorous degree of active power raises) relates to again storage battery manufacture in charging process and the dehydration degree (situation will go to bits the day after tomorrow of life entity) of formula (the inborn inherent cause of life entity) storage battery, causality is often difficult to find, conventionally we think when finding, all no longer to pursue accuracy abandoning finding causal traditional preference, sometimes obtaining 2 adds 2 and approximates 3.9 result, also all well and good, in order to understand development trend roughly, be ready that accuracy is made to some gives way and take expensive 0.21H two-forty charging and reach and respect the natural law that storage battery accepts electric weight after core object and as prerequisite takes a step back, reduce flexibility ratio that charge rate reaches the core object of 5.1H (or the >5.1H again taking a step back) charging cheaply and excavate the charge rate that storage battery " has that storing or potential just in dormant state " and promote 19 times, electric flux loss reduces approximately 44.5%, approximately 4.5 times of lifes.

To one group of nominal capacity 400AH; Nominal voltage v ₂aCDC output idle capacity A for the lead-acid battery of=480V _m>=2400A; Output v=561.6V can reach 3.923C charge rate be full of 80-90% electric weight in < 0.21H while being controlled by the charging of flexibility under PFZNR loop control after, by gear shift, be ACDC output idle capacity A _m>=24A; Output v=561.6V can reach 0.03923C charge rate, is full of 10～20% remaining electric weight, when one group of nominal capacity is reduced to 4AH from 400AH, nominal voltage at>=5.1H v ₂during the lead acid battery charge of=480V 0.03923C speed can automatically rise to again 3.923C speed can be to nominal capacity 4AH in≤0.21H; Nominal voltage v ₂=480V lead-acid battery is full of 80%～90% electric weight.Originally charge rate unit of measurement is to correspond to the nominal capacity of storage battery complete (10 one-tenths) newly time, and storage battery is again congenital heredity factor (technique during manufacture and formula) according to life entity and posteriorily discharges and recharges middle R _c+ R _ethe situation that goes to bits (degree of dehydration) determine that himself is from ACDC's vend storage is received into the true capacity (being not necessarily equal to nominal capacity) of electric flux with from ACDC's vit is the deciphering at another visual angle of two-forty charging and low-rate charge flexibility ratio that termination is subject to the true speed of electric flux.

Fill people and measure the relation between record and memory space record:
