Using software to switch cells in and out of series strings can improve overall battery life and performance, reports Barrie Lawson of CHEEVC Ltd.
This paper describes how battery performance can be improved and its functionality enhanced by software control of the individual cells in the battery chain. The project was initially set up to find ways of improving high rate battery performance by using cyclic redundancy to enable rest periods to be introduced during both charging and discharging. The solution found gave rise to some surprising results and opportunities.
