This luminous energy collecting board 11 is plasticity, and can be according to being set as the shape that needs;

According to the composition of said elements circuit, charging of the present invention, control action, effect are described as follows:

One, luminous energy charging; See also Fig. 2, Fig. 4, Fig. 4 A, luminous energy collecting board 11 is collected luminous energy through irradiate light, and convert electric kenel at light, power conversion circuit 13, this moment, amber light indicating circuit 12 action amber lights were bright, this power supply is complete direct current by the full complete stream circuit 62 effect purifying of high frequency respectively, and be controlled in the situation that meets battery 7 through voltage protection control circuit 15, make the suitable power supply of master control IC crystal 8 control (being little electric current during for example low, high temperature) output, and form charge circuit battery 7 chargings; The charge condition of this luminous energy charging is according to the V(inlet of charging)=V1(external power amount)-V2(battery standing crop)+the Vd(amount fixed according to temperature), and D6 is a kind of temperature sensitive transistor, but sensing temperature, voltage, as the charging input variable data (about the relation of temperature and charging, state clearly again after the appearance), its current inductor 14 is perception battery 7 electric weight situations at any time just, whether reach the charging critical point, as the auxiliary monitoring of master control IC crystal 8 actions; Luminous energy charging control therefore of the present invention just has the function of intelligent automatic interpretation, control adjustment.

Two, external power is (as AC, automobile power source) charging: see also Fig. 2, Fig. 5, Fig. 5 A, when external power is 12V when input through rectification, green light indicating circuit 3 action green lights are bright, and master control IC crystal 8 is accepted the signal of temperature regulating gate circuit 10, inputing to power supply input automatic circuit 4 cooperates, make charge power supply import automatic circuit 4 according to battery 7 existing power supply amounts through power supply, temperature conditions and be suitable input current input current input regulating gate circuit 5 by standard, the side must be by circuit and at the complete rectification circuit 61 of high frequency, 62 direct current electrifications again, in battery 7 situation and charging according to need, red light indicating circuit 9 i.e. actions this moment, the bright indication external power of red light charged state; And form one and have the charging work done of doing correct interpretation, adjustment, control according to external power, battery situation according to power supply input automatic circuit 4, electric current input regulating gate circuit 5, temperature regulating gate circuit 10.

Three, temperature regime charging control: battery 7 chargings are because of being subjected to the materials used limiting factor, its temperature of allowing charging is in 5 ℃～50 ℃ scopes, and 1 ℃ of its every intensification, the change of voltage is about 15mV, battery 7 temperature rises and charging voltage, voltage are proportional, thereby at the abnormal ambient conditions of temperature, the charging current of battery 7 must be charged with minimum, can avoid battery 7 temperature influences and Fa Gaore or explosion damage rapidly; Thereby the chargeable work done minimum current input value of the present invention's design is 0.1mA, and be 50mA～350mA safe current in the normal condition charging current, when the external environment temperature below 5 ℃ or more than 50 ℃ the time, import processing by current inductor 14, temperature regulating gate circuit 10 with THI, TLO, the TEMP of TH1 and master control IC crystal 8, make the input power supply can be the slowly charging of atomic little electric current (about 0.1mA) amount, though it is longer that the charging interval needs, than traditional type control can't charge or to destroy battery accidentally better; Thereby the present invention is to the temperature effect battery situation in when charging, have adjust adapt to, the effect of protection.

Four, memory-less effect almost: existing battery " memory effect " be meant when battery be used to non-zero voltage (though can't work done use, but in the time of remaining atomic small voltage), be recharged input former remaining power supply memory is accumulated, so repeatedly accumulation will be dwindled the chargeable capacity of battery; In addition, electricity is permitted battery and is not used up as yet, and still surplus have a small voltage power supply (as 8V), is compelled to charge into high voltage (as 12V) again, this small voltage power supply promptly can be forced to the dull effect of memory, is to determine whether battery has the factor of " memory effect " so the voltage during charging cooperates; The present invention promptly can control it according to above-mentioned control basis, see also Fig. 7, when using, when the voltage that current inductor 14 formulas are surveyed is lower than the setting voltage critical point, in following step-down 5mV scope, master control IC crystal 8 promptly can be carried out the charging action according to the identical magnitude of voltage of the critical point value of setting voltage, allow battery can not form remaining LVPS, or when not using complete power supply, understand interpretation magnitude of voltage at that time during its charging, be controlled in identical charging voltage value by master control IC crystal and be recharged, and do not have the situation of big voltge surge small voltage, surely not cause former small voltage power supply to be forced to memory and stagnate and be stored in battery; The present invention from the above can keep the unlikely emptying of battery and be charged by identical pressure according to voltage, and does not almost have " memory effect ", prolongs the useful life of battery.

Five, can use in simultaneously the charging; See also figure six, battery supply is when using consumption to descend, promptly move charging (as shown in Figure 4) to the IC of the critical point current inductor 14 master controls elder generations crystal 8 luminous energy charging systems that charge, impel battery electric quantity to rise once again, and can not be lower than under the charging critical point, and the supply voltage system of charging input is identical with the charging critical point voltage.So the present invention can charge automatically and keep the battery electric quantity can amount of work and prevent battery " memory is imitated ", does not have the misgivings of not enough electric weight during use, and is very convenient.

Six, charge with regard to efficient: be example with actual test value now: with the charging input voltage is Vin=12.05V, and charging input battery is Iin=0.925A, and it then is Pin=12.05 * 0.925=11.15W that the charging input amounts to power; And charging is finished after tested, it forms output voltage is that Vout=10.6V, output current are Iout=0.956A, its power output adds up to Pout=10.6 * 0.956=10.13W, WPout=Pin-Pout=11.15W-10.13W=1.02W, its efficiency value=WPout/Pin%=91.47%, that is about 92%, it is investigated that the charge efficiency value of general chargeable battery then is about 80%; By above-mentioned promptly as can be known, charge efficiency of the present invention is high more about 12% than traditional charge efficiency, is the high efficiency charging.

Comprehensively above-mentioned, the present invention overcomes the shortcoming of tradition charging control really fully, battery charge is to monitor, adjust, control electric current and voltage and charges according to intellectual selections such as temperature regime, processing, make battery Chang Baoke work done electric weight, memory-less effect almost, and then reach effect easy to use, that battery life prolongs.
