-220 Lithium-ion Battery Protection Board Checker
Lithium battery protection board is an important component of battery. The quality of protection
board would definitely affect the function of battery and safety usage for users. The full function and
high testing efficiency of the newly-developed testing instrument can help guarantee ‘zero’ defects.
Through its composite double-voltage
testing, some time the testing only needs 5 seconds, fast and
No need to connect to computer, single interface(25 probes), plug-and-play.
Multi-function keyboard, set up testing parameters then start testing just with simple press.
Larger LCD can help you operate and check testing parameters with ease. (Five parameters will
Precise testing for OCUR(the value of over current protection )
3. Tester Type
BPC -220 is newly made for the testing of lithium battery protection board. (Professional testing
4. Function Illustration
(1) Over-charging protection and protective voltage
(2) Over-discharging protection and protective voltage
(3) Over current protection (Max. current: 7.0 A)
(5) WCUR(work current of the board itself):
User sets up DT, voltage and error, the tester would memorize the parameters then shows
whether is qualified or unqualified. Red means unqualified and green refers to qualified.
Use the same method to test the function as defined in (2) and (3).
Maxi. overcharge: 4.45V/cell, Mini: 4.00V/cell
Maxi discharge: 2.99V/cell Minimum: 2.00V/cell
Mini. current: 1.0A, Maxi. current:7.0A( 0.2A/Step)
ONSIGA TECH BPC -220 (1) work current consumption WCUR
(8) Over current protection delay time (OCUR-DT)
7. Testing and Setting
Load the board onto the fixer, press slightly to made sure connected well, then press ‘READY’ to start
the testing. It can be released only after the testing finished.
7-2. Parameter Setting (7.2V Lithium battery protection board, 2 Cells) For reference
CHG protection: Normal voltage: 4.35V or 4.25V/cell
DIS protection: 2.50Vor 2.3/cell(normal voltage)
User can set the maxi and mini parameters according to error.
E.g.: CHG4.35±0.05V, DIS2.50±0.10V, OCUR3.5±1.0A, IMP60±10 mΩ, WCUR6±2µA,
CHG-DT 600 ms (Choose the maxi. error and set parameter slightly larger by adding 100ms)
DIS-DT 400 ms (Choose the maxi. error and set parameter slightly larger by adding 100ms)
OCUR-DT 40 ms(Choose the maxi. error and set parameter slightly larger by adding 10ms)
(*Due to the limitation of testing, delayed time (DT) is not set in the table For reference only).
Precise DIS-DT: ±5% +8ms (every second, add 0.1s)
Maxi. CHG-DT: 8.0S (User can set as needed)
Maxi. DIS-DT: 990mS (User can set as needed)
Maxi. OCUR: 98ms (User can set as needed)
Red: Not pass (Exceeding the range set in 9-2)
Green: Pass (Within the range set in 9-2)
8.1.1 Watch the testing result (Display)
The testing result for every parameter will show on the correspondent places)
Not qualified (IMP not pass shows in the Figure)
ONSIGA TECH BPC -220 Set parameter according to different board, see 9-2. After setting, press ‘Confirm’ then press ‘Auto’ to
start the testing. (The DT should be longer than actual testing time) (AUTO 000 Ready)
C. Over current protection delay time (OCUR-DT)
Press ‘Set’, it shows as follows by step:
Press ‘Up’ or “Down’ to change parameters (see 7.2)
After setting, save it then start testing
While turning on power, user should check the setting of DIS-DT, the time set should be longer than
actual delayed time) (See 7-2) (CHG-DT is set as 400ms and DIS-DT is set as 200ms before delivery)
Ocur-DT is 40ms, Press ‘AUTO’ then start the testing. (AUTO 000 READY will show on the display)
(1) Load the board onto the fixer and make sure well connected then press ‘Ready’
(2) Tester will start testing and “test” will show, when testing is over, “END” shows. DO NOT release
(3) Read testing value and take down testing result.
Tester will test the board automatically according the parameters set and it will tell whether it’s
qualified or not. The testing is very quick. If needed, user can change the parameter setting.
(1) Load the board onto the fixer and make sure well connected then press ‘Ready’.
(2) Tester will test the board automatically according the parameters set and ‘TEST’ will show. When
testing finishes, ‘END’ shows. DO NOT release the board before finishing.
(3) After testing, tester will tell whether is qualified or not. If current item is passed, it will test next
item and PASS shows when testing is over.
(4) OK indicates ‘Qualified’ and green light is on. Whenever it is unqualified, ‘×’ shows and red light is
Press this key to choose ‘Beep’ or ‘Mute’.

2 Time limit for DIS DT is too short; Increase setting value of the
time set for DT is longer than actual over charge delay time.

PCM and should wait to discharge short, it will affect the
Note: When there is bypass condenser or larger R/C delayed condenser, it will affect the actual value of
DT, two different test result will Occur.
E.g., when testing OCUR, user presses ‘AUTO’ or ‘Set’, the parameter set for ‘Set’ mode should be
larger than ‘AUTO’ code, or it may not pass.
‘AUTO’ will test the consistent protection current.
‘Set’ will test the protection current during the instant testing period within the range set.
