10 Battery Temperature Compensation

10.3 Using the TempCo Option

When ATevo is equipped with a temperature compensation probe,
it auto-adjusts output voltage applied to the battery to keep float
current constant, thereby avoiding overcharging and undercharging.
The probe senses battery temperature variation and adjusts output
float/equalize voltages to compensate. If battery temperature
increases, ATevo's output voltage decreases. If you are experiencing
any inconsistencies in ATevo when the probe is installed, temporarily
disable the TempCo Option per Section 4.3.9.
NOTES
• Set Float and Equalize voltages to the values recommended by
the battery manufacturer for 77 °F / 25 °C.
• When you enter or adjust Float or Equalize voltage, the front
panel meter displays the 77 °F / 25 °C value, even if the battery
is warmer or cooler than 77 °F / 25 °C.
• ATevo's actual output voltage may be different from the set
point, if the battery is warmer or cooler than 77 °F / 25 °C.
• Use a digital multi-meter to measure the actual dc output
voltage. Determine temperature at the compensation probe,
and use the graph in Section 10.4 to verify that output voltage is
correct.
• If battery temperature falls below 32 °F / 0 °C, there will be no
further increase in ATevo output voltage. Likewise, if battery
temperature rises above 122 °F / 50 °C, there will be no further
decrease in output voltage.

10.3.1 Home Screen with TempCo Option

Additional parameters appear on the HOME SCREEN when the
TempCo option is installed and enabled.
• The LARGE FONT voltage value is the actual charger output
voltage, compensated for the present battery temperature.
• Present battery temperature (in °C) appears in small font to the
right of the actual charger voltage.
