Figure 4-35 Internal resistance test setting
Notice: Constant resistance Minimum value = minimum discharge voltage / range current, maximum value =
range voltage / (range current x 0.2%).In the process of step setting, "shelving" should be carried out
between discharge and charging steps to facilitate stability. The maximum number of cycles does not exceed
65,535.
Step Condition
Users can set step recording conditions, protection conditions, formation voltage change rate, professional protection
conditions, etc.
1. Record condition
Recording conditions of the BTS9 battery test system. The relationship between recording conditions and conditions is
logical. As long as any condition is met during the test, the data will be recorded for once. Appropriate selection of
recording conditions, such as long time intervals, can keep data files as small as possible but ensure that required data
is not missed. Only digits can be recorded. Both voltage and current intervals support decimal points.
Channel recording conditions: time interval, voltage interval, and current interval, as shown in Figure 4-36:
Time interval: The system records a set of data at an interval. The BTS9000 interval is an integer multiple of
1ms and does not support negative values.
Voltage interval: The system records a set of data when the voltage difference between the recorded data and
the recorded data reaches a preset value.
Current interval: When the difference between the recorded current and the recorded current reaches the set
value, the system records a set of data.
2. Protection condition
Hardware protection is provided for the channels with abnormal battery current and voltage sampling during the test.
1 Channel protection condition: including voltage/current upper and lower limits, capacity protection, check back
deviation, as shown in the following figure:
Figure 4-36 Channel recording condition Figure 4-37 Channel protection condition
Voltage upper/lower limit: When the battery voltage exceeds the preset range, the channel enters the security
protection state.
Current upper/lower limit: When the battery current exceeds the set range, the channel enters the safety
protection state.
Capacity protection: When the battery charging capacity reaches the set value, the channel enters the safe
