Method for charging a battery
First Claim
1. A method for charging a battery having a control device that influences a charging current for the battery in a predefined manner and carries out at least two different charging methods, the method comprising:
- in a first charging process, maintaining a substantially constant voltage;
in a second charging process, taking measures resulting in dynamization; and
in the second charging process, forcing discharges at predefined instants by one of switching on a predefined consumer and de-exciting a charging device.

Abstract
Provided is a method for charging a battery that dynamizes the charging phase of the battery, thereby enabling optimum charging. The dynamization of the charging phase is intended to achieve effective mixing of the battery acid and/or depolarization of the electrodes and ultimately result in improved receiving of the charging current. In this context, the charging method can be carried out according to at least two different methods. In a first method, targeted discharges result in depolarization of the electrodes due to locally decreasing acid density, and in a second method the battery acid is reliably mixed as a result of temporary increasing of the charging voltage via the so-called gassing voltage of the battery. Both methods result in improved battery charging. In an embodiment of the method, the two methods are combined.
