1: I phase (bulk)
At the beginning of the charging process, the flat battery is charged with a constant
current (100 % charge current) until the battery voltage reaches the charging end
voltage. The charging current decreases when the battery has reached this charging
level.
2: U0 phase (absorption)
Now the absorption charging process (U0 phase) begins, where the duration
depends on the battery. The voltage remains constant (U0).
This phase is limited to maximal 3 hours to prevent overcharging the battery while
driving.
3: U phase (float)
After the U0 phase, the battery charger switches to conservation charging function
(U phase).
