Parameters
•
“hvc”
(high voltage cutoff) is the high voltage limit at which the BMS will open the HLS
•
“
lvc
”
(low voltage cutoff) is the low voltage limit at which the BMS will open the LLS
•
“hvcc”
(high voltage cutoff clear) is used to buffer cycling of the High limit switch. If a
cell reaches HVC during charge, the BMS will shut off the charger, and the cell voltage
drops slightly. The charger will turn back on below HVC, and the cycle repeats. Setting
the HVCC below the HVC creates a delay to eliminate rapid cycling. The charger turns
back on only after the highest cell voltage drops below HVCC.
•
“
lvc
c”
(low voltage cutoff clear) works the same as HVCC, but responds to the low end
of the cell voltage range. This allows for turning the load back on only after the lowest
cell voltage rises above LVCC.
•
“tmax”
maximum temperature in Centigrade for charge or discharge
•
“tmin”
minimum temperature in Centigrade for charge or discharge
