Rapid battery charging

A battery charger for two or more batteries, comprising:

• a pulse generator configured to generate a charging pulse group having a positive pulse for a charging time period and a rest period for a rest time period and sequentially apply the charging pulse group to each of the two or more batteries such that the positive pulse is only provided to one of the batteries at a time;
• a detector configured to monitor one or more parameters for the two or more batteries;
• and
• a processor communicably coupled to the pulse generator and the detector, the processor configured to determine the charging series time period, the charging time period and the rest time period based on the one or more battery parameters.

A method for charging two or more cells within a battery with a battery charger, comprising the steps of:

• providing the battery having a number of cells electrically connected to the battery charger, wherein the number of cells comprises the two or more cells, and the battery charger comprises a pulse generator, a detector and a processor communicably coupled to the pulse generator and the detector;
• determining a charging time period and a rest time period based on one or more cell parameters using the processor and the detector;
• generating a charging pulse group having a positive pulse for the charging time period and a rest period for the rest time period using the pulse generator;
• and
• sequentially applying the charging pulse group to each of the two or more cells such that the positive pulse is only provided to one of the cells at a time.
