Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

The utility model provides a kind of batteries distribution on line formula active equalization management system as described in figures 1 and 5, Including CPU master controllers, working power circuit, active equalization regulation circuit and cell measurement circuit, the CPU master controllers Power input and RS485 communication interfaces are electrically connected with, the CPU master controllers respectively with working power circuit, active equalization Adjust circuit and cell measurement circuit is electrically connected with, the active equalization regulation circuit and cell measurement circuit are electrical with battery Connection.

Operation principle：One batteries distribution on line formula battery detection module is used for a batteries detection, in mould Block indoor design active equalization function, the Communication Control that distributed battery monitoring modular receives higher level's monitor starts equalizing circuit Export 8A charging currents, this batteries charged, be this batteries can quickly improve voltage and battery capacity and battery pack its Its battery keeps corresponding consistent, maintains the equilibrium of whole group battery.

As shown in figure 4, active equalization regulation circuit uses high frequency switch power technology, and design circuit of synchronous rectification and carry The electric energy efficiency of high Power convert, makes equipment heating amount few, stable and reliable operation, and active equalization regulation has to battery charging Ration the power supply current charge and constant voltage charging, prevent over-charging of battery and high voltage from causing battery performance to decline.

As shown in Fig. 2 because lead sulfate produced on positive plate, minus plate when charging can be decomposed also in charging Original gradually increases into sulfuric acid, lead and lead peroxide, therefore the concentration of battery electrolyte inside, that is, the proportion of electrolyte rises, and The concentration gradually returned to before electric discharge, this change shows that the active material in battery has reverted to what can be powered once again State, when the lead sulfate at the two poles of the earth is reduced into original active material, i.e., terminates equal to charging, and minus plate just produces hydrogen, Positive plate then produces oxygen, when being charged to final stage, and electric current is nearly all used in the electrolysis of water, thus electrolyte can reduce, now It should be supplemented with pure water.

As shown in Figure 3-4, working power circuit provides stable 5V ,+12V, -12v outputs by high frequency switch-mode.It is right For high frequency switch power, ac input voltage can be boosting before entering transformer (being usually 50-60 KHz before boosting). With the rise of input voltage, the head of the component such as transformer and electric capacity is just without as linear power supply so big.It is this Required for high frequency switch power exactly our personal PC and the equipment as VCR video recorders.It should be noted that I Often described " Switching Power Supply " be in fact " high frequency switch power " abbreviated form, and power supply closing in itself and open-type There is no any relation.Closed loop system (closed loop system) --- the circuit of charge control switch pipe, from power supply Output obtain feedback signal, then increased according to PC power consumption or reduce the frequency of the voltage in a certain cycle so as to energy Enough adapt to the transformer of power supply (this method is referred to as PWM, Pulse Width Modulation, pulse width modulation).So Say, Switching Power Supply can be adjusted according to the size of the power consumption for the current consuming apparatus being attached thereto come self, so as to allow transformer And other components take away lesser amount of energy, and reduction caloric value.
