Battery Temperature Compensation
Battery chargers with a TC in the model number have a feature that will
automatically adjust the output voltage as a function of battery temperature with
an optional temperature probe cable. The temperature probe is mechanically
attached to one of the battery interconnect posts, and the other end of the cable is
plugged into the connector located on the front face of the Control Module.
Both NiCd and lead acid chemistries are supported with Voltage/Temperature
curves suited for each. The type of the probe determines whether the charger is
set up for NiCd or lead acid charging. In either case, at room temperature (70 °F),
the voltage is set to 72 Volts. As the temperature of the battery decreases, the
voltage increases. As temperatures increase above room temperature, the voltage
applied to the battery decreases at a lower rate. If the temperature probe is
disconnected from the Control Module, the charger reverts to a constant 72V
regardless of the battery temperature.
The part number for the NiCd cable is TPCN-XX and the lead acid is TPCL-XX.
