A kind of electronic simulation storage battery

Technical field

The present invention relates to a kind of electronic simulation storage battery, be specifically related to a kind of storage battery charge control circuit.

Background technology

At present, when charger and motor in electric automobile are made a service test, the electric weight of supplying cell all need be bled off or be full of, the waste test duration has also been wasted a large amount of electric energy simultaneously, and been has frequently has been discharged and recharged, and can increase the internal resistance of cell, influence test effect.

Summary of the invention

At problems of the prior art, the purpose of this invention is to provide the low electronic simulation storage battery of a kind of experimentation cost.

A kind of electronic simulation storage battery, it is characterized in that comprising rectification and pfc circuit, DC/DC translation circuit, output circuit, booster circuit, controllable load, CPU processor, display and control circuit, described control circuit contains amplification module 1, time coarse adjustment module 2, time accurate adjustment module 3, pressure regulation Executive Module 4; Below in conjunction with accompanying drawing above-described partial circuit module is described further:

1, amplification module 1: when imitated storage battery was worked, the electric current of output circuit was amplified into time coarse adjustment module and time accurate adjustment module through IC8-2, IC8-1;

2, time coarse adjustment module 2: the electric current of entry time coarse adjustment module is by selecting the frequency of gear control IC1, thereby control discharges and recharges time range, when current range is 10-30A, electric current is by the IC2-1 gear, and when current range was 30-90A, electric current was by the IC2-2 gear, when current range is 90-180A, electric current is by the IC2-3 gear, and when current range was 180-300A, electric current was by the IC2-4 gear;

3, time accurate adjustment module 3: the electric current of entry time accurate adjustment module amplifies through IC7, the frequency of control IC1, and when the rising of R22 place voltage, then time accurate adjustment module output voltage raises, and the frequency of IC1 raises, and reduce discharge time;

4, the pressure regulation Executive Module 4: after determining the time of discharging and recharging, the Q12 of IC1 or Q13 output high level, Q12 is the discharge output port, and Q13 is the charging output port, and AN1 is for discharging and recharging control switch, the high level of the Q12 of IC1 or Q13 output enters IC9 control voltage gear R32-R41 by the CLK end, by selecting the resistance control voltage up-down of R32-R41, the variation that C21 can the buffer voltagc lifting, the voltage rising at IC8-4 place, then the controllable load resistance becomes big, and charging voltage raises.The high level of the Q12 of IC1 or Q13 output resets by R9, because IC9 control voltage gear has 10, then every 1/10th discharge and recharge the time, resets once.

Owing to adopt technique scheme, advantage and good effect that the present invention has are: can realize that Single-chip Controlling electronic simulation storage battery can control the voltage electric weight of battery at any time, regulate its voltage charge value as required, save test duration and test electric energy, thereby reduced experimentation cost.
