Title: Two-stage battery charging procedure - uses time period of high charging rate and occurrence of gasification to determine lower charging rate time period
Inventor: FIEDLER NORBERT
IPC: H01M10/44
Filed: 1976-08-28
Abstract: The battery charging system for lead/acid batteries, charges the battery at a high rate until gasification occurs, then a low charging rate for a predetermined time. The time taken for the first stage is measured, and based on the ratio between the two stages, this time is used as a basis for establishing the line required for the second stage. The time may be measured by a mechanical system or by an electronic device. The device is stopped when gasification begins and the line registered is used by reversing the device for establishing the second stage. Gasification is established by monitoring the liberation of hydrogen and oxygen when they undergo recombination and form water.
