APPENDIX D
– NOTE ON TEMPERATURE
COMPENSATION
Temperature compensation is critical to maintaining battery life and performance. If
the battery temperature is allowed to drift higher or lower than 77°F during normal
operation, the charger constant voltage limit should be adjusted to compensate for
temperature variations.
For a valve-regulated lead-acid battery, the temperature compensation factor is 2
mV/°C/VPC. The
REVOLUTION™
opportunity charger implements two temperature-
compensation coefficients:
1. The battery low compensation coefficient (
Batt Low Temp Comp
) is activated
when the battery temperature is different than 77°F, but lower than the high
compensation temperature limit (
High Comp Temp
) (Figure C1).
2. The battery high compensation coefficient (
Batt High Temp Comp
) is activated
when the battery temperature is higher than the high compensation temperature
limit (
High Comp Temp
)
(Figure D1).
Figure D1
These parameters can be factory or dealer adjusted.
