Connect tested battery, the output terminal connection operational amplifier of the tested battery, the output terminal connection electric current of the operational amplifier
Voltage A/D modular converters, the output terminal connection CPU of the Current Voltage A/D modular converters.
The utility model is using CPU collocation power module, Current Voltage A/D modular converters, PWM constant-current controllers and bears
It carries and volume test is carried out to single battery so that manufacturer can integrally carry out accumulator reasonable combo, and equilibrium collocation can
Accumulator back amount after sale is greatly reduced, and tests and does not have to insert alternating current, inside is equipped with accurate regulator circuit, measuring accuracy
Height, applicability is wide, noiseless.
Preferably, voltage display module, electric current display module, timing module and capacity are connected on the CPU and shows mould
Block, the voltage display module, electric current display module, timing module and capacity display module are all connected with LED digital display tubes.
When this kind of structure causes its test, show that the content of screen display is more comprehensive, so as to be further ensured that its test
It is more accurate reliable.
Preferably, control circuit of intelligent fan is also associated on the CPU, is connected on the control circuit of intelligent fan
Radiator fan.
This kind of structure causes it to have independent heat-sink unit, and more accurate reliable to the control of radiator fan, it is ensured that its
Heat dissipation effect.
Preferably, the voltage unit that the LED digital display tubes are shown is V, current unit A, time of day is divide
Clock, bodge Ah.
This kind of structure so that its voltage shown, electric current, time and capacity are more intuitive, easily readable.
The utility model is using CPU collocation power module, Current Voltage A/D modular converters, PWM constant-current controllers and bears
It carries and volume test is carried out to single battery so that manufacturer can integrally carry out accumulator reasonable combo, and equilibrium collocation can
Accumulator back amount after sale is greatly reduced, and tests and does not have to insert alternating current, inside is equipped with accurate regulator circuit, measuring accuracy
Height, applicability is wide, noiseless.
Description of the drawings
Fig. 1 is the circuit module connection figure of the utility model.
Specific embodiment
The utility model is described in further detail with test process below in conjunction with the accompanying drawings, but is not to this practicality
The limitation of novel protected range.
As shown in Figure 1, a kind of passive intelligent accumulator capacity detector, including CPU, is connected on CPU input terminals
Control handle, start-stop button, set key and power module, the PWM constant-current controllers being connected on CPU output terminals and LED are digital
Display tube and the load being connected on PWM constant-current controller output terminals, the tested electricity of connection on the input terminal of the power module
Pond, the output terminal connection operational amplifier of the tested battery, the output terminal connection Current Voltage A/D of the operational amplifier turn
Change the mold block, the output terminal connection CPU of the Current Voltage A/D modular converters.Voltage display module is connected on CPU, electric current is shown
Show module, timing module and capacity display module, the voltage display module, electric current display module, timing module and capacity are shown
Show that module is all connected with LED digital display tubes.Control circuit of intelligent fan, the control circuit of intelligent fan are also associated on CPU

Nominal voltage：Battery such as 12V shows -12-, and the battery of 16V shows -16-, the actual voltage value of battery shown after 3 seconds, so
Discharge current is set according to the amount of capacity of battery afterwards, acquiescence is 10.00A；Then it clicks start-stop button and starts instrument, open
Beginning discharge test, after discharging into final voltage, instrument is automatically stopped, automatic to show discharge time, can rotate control rotation
Button checks that the actual capacity reading of battery, such as the cell testing results of new 20Ah should be put 20.00 or so according to this
Electric time and capacity reading judge the fine or not degree of battery.
After one group of battery discharge, the starting voltage per batteries all always, repeatedly after charging discharges and reaches whole group again
The purpose of battery equilibrium.
