Battery Temperature Compensation
The temperature compensation value is from 25°C, so 40°C-25°C = 15°C x -0.06V/°C = -0.9V + 28.6V = 27.7V. So the battery charge voltage at 40°C would be 27.7V. Example 2: let''s use a 12V system, with a charge voltage of 14.1V, a temperature compensation value of -3mV/°C/cell, and a battery temperature of 5°C.
