Described CPU and memory adopt ripe prior art products, can preserve the supplemental characteristic of special-purpose software and setting etc. in the memory.
Described accumulator adopts ripe prior art products, for example preferred super capacitor; Described accumulator bank is the super capacitor group.
Operation principle:
Embodiment 1: as shown in Figure 1; DC source is at first filled electricity to accumulator; charge the battery again by accumulator then; the applicant is customized for the buffer-type charging; sort buffer has replaced buck circuit commonly used usually; and the discharge characteristic curve of super capacitor and battery charge characteristic curve are very approaching, can improve charging quality and the effective battery in the protection charging.In the present embodiment, also be provided with negative pulse unit before the battery, with the mode battery discharge of negative pulse, its benefit is exactly the battery that is charging in order to protect to its purpose under the control of CPU.The charging of sort buffer formula is carried out overall situation control and management by CPU and memory.At first, battery detection unit detects battery and connects, and native system just can enter work, if do not insert battery, system is in resting state.When the voltage that detects accumulator when accumulation energy detection unit was lower than a certain set point, the cpu instruction driver module of CPU and memory was connected buffer switch, disconnects alteration switch simultaneously, and DC source is to charging accumulator.When the voltage that detects accumulator when accumulation energy detection unit reaches a certain set point, the cpu instruction driver module of CPU and memory disconnects buffer switch, connect alteration switch simultaneously, DC source quits work to charging accumulator, accumulator begins to battery charge simultaneously, when the voltage of accumulator is lower than in a certain set point, be returned to buffering and charging work that previous state carries out next circulation again.After battery detection unit detected battery and has been full of, native system entered floating charge state automatically, and after battery was not removed, native system just quit work.
Embodiment 2: as shown in Figure 2, be not difficult to find out that the technical program embodiment is the extended pattern of technical scheme 1 embodiment.Operation principle is the same substantially with technical scheme 1, different is, DC source, buffer switch, accumulator, alteration switch and battery are replaced by DC power supply, buffer switch array, accumulator bank, alteration switch array and battery interface respectively, and the battery here and the individual interface of battery interface are same notions.Under the control of special-purpose software, open close by control buffer switch array, accumulator bank, alteration switch array realized the buffering charging.In the present embodiment, can realize battery number, utilize accumulator randomly to battery charge arbitrarily according to needs charging in the detected online battery.Here the said battery number that needs to charge is to be less than or equal to online battery number.Their buffering charging work is that the CPU of CPU and memory realizes by the break-make of controlling each switch in buffer switch array and the alteration switch array.After online all batteries were full of, native system entered floating charge state automatically, and after all batteries were not removed, native system just quit work.
The metering method of above-mentioned buffer-type charging system charge capacity derives from the following computing formula that the applicant derives out:
The starting voltage of 1. establishing super capacitor in the i time buffering course is V
Is, it is V that buffering finishes the back
Ie, then this is buffered to the electric weight Q of super capacitor inside
i=CV
Ie-CV
Is=C (V
Ie-V
Is)=C Δ V
iWherein, Q
iIt is the electric weight that is buffered to super capacitor inside in the i time buffering course; C is the capacity of super capacitor, Δ V
iBe that buffering begins to the variable quantity of buffering end back super capacitor terminal voltage.
2. if, be recharged object and charged and finish, then charge into total electric weight of the object inside of charging through behind N buffering exchange process:
Wherein Q is the total electric weight that exchanges to charging object inside after charging is finished.
Beneficial effect of the present invention is:
1, provides a kind of method that switch type charges to battery that cushions. Namely at first with the energy storage component of energy snubber to the centre, by the discharge of energy storage component, realize the charging to battery again. If the discharge current curves of energy storage component is consistent with the charging current curve of battery, a kind of battery charging modes of the best then can be provided, improved charging rate, prolonged the service life of battery.
2, owing to can adopt the electrochemical capacitor such as ultracapacitor as the energy storage component of buffering. Super capacitor has the characteristics such as capacity is big, internal resistance is low, charging rate is fast, therefore once cushioning exchange process can exchange to more electric weight the inside that is recharged battery, so can reduce the operating frequency of switching device in the circuit, therefore reduce the oneself power consumption of system.
3, can in the buffering exchange process, introduce the negative pulse that battery is sparked, thereby make the charging process of buffering exchange have certain repair function to battery.
4, exchange the basic principle of charging method according to buffering, can form the buffer queue formula one to one, the charge mode such as one-to-many, many-one, multi-to-multi, realize that a plurality of DC sources are recharged the battery charging to a plurality of simultaneously, so can greatly improve charging rate and charge efficiency.
5, by regulating the time interval of twice adjacent exchange process, charging effect can be controlled at optimum state.
