Lithium Battery Pack 1-24 Series Protective Plate (BMS) PCB Tester
Intorduction:
The PBTS multi-function protection board test system is mainly used to detect whether the functional indicators
of the power battery protection board are within the range of parameters, so as to provide a set of testing
standards for the staff
Test functions include: overcharge protection voltage, overcharge recovery voltage, overcharge protection
voltage, overput recovery voltage, overdischarge current protection, short guarantee performance test, charging
current protection, balanced open voltage, balanced real-time current, total self-consumption current of protection
board, single section self-consumption current.
Feature:
♦ Short circuit protection test (means the true short circuit
protection test at the microsecond level)
♦ Single self-consumption test (worth core current for each
protective plate trumpet)
♦ Equilibrium current and balanced voltage (of accurately grasping
the balanced current and balanced voltage)
♦ When the core voltage is too low, the current is too high, and the
voltage is inconsistent, the protection plate
will play to power off the whole battery pack
♦ You can test the voltage and overdischarge current of the
protection plate
♦ Items can be tested according to customer requirements, in which
the performance parameters of the
protection board are accurately tested
♦ Quick mode quickly determines whether the protection board
parameters are within the set range
♦ Super capacitance, fully simulate the PACK battery voltage,
instant short circuit to the protection plate,
accurately capture the short circuit time and current

FAQ
FAQ
A: The battery pack can be charged and discharged normally, but after a period of time a cell voltage to 0 v?
B: When a section of the protection board leakage state of a capacitor (usually leakage current will be very small,
the maximum milliampere level) connected to the battery after the use of equipment can not detect the battery
leakage performance, this energy-saving cell power consumption by the protection board has been consumed,
in the consumption before the end of the timely charging, this group of batteries will be scrapped. Therefore,
it is recommended that the battery cell must be tested before installing the protective plate, and each section
of the protective plate consumes its own power.
A: Each cell is strictly paired, but each cell has a different voltage after a battery has been in use for some time?
B: The inconsistency of battery voltage may be caused by the difference of self-consumption of single cell,
or the change of internal resistance of cell during discharging.
A: Charge and discharge aging when why will find the battery protection in advance?
B: Battery protection in advance may be a section of protection plate protection voltage value is not, or the
battery charge and discharge cycle after the internal resistance changes. At this point can be used under
the precision multimeter each battery voltage is consistent, if it is consistent that is the protection plate
problem, otherwise for the cell problem.
A: Two Protection Plate over-current protection value is the same, why is one connected to the load will be protected,
the other can discharge normally?
B: When the Protection Board is designed, each parameter has a delay value, only when the parameter
duration is longer than the delay value, the protection board will play its role and the whole battery will be
cut off. The delay data can be adjusted appropriatel
