The capacity of lead/acid batteries decreases with the number of cycles. This process is known as ageing. The reduction of capacity affects not only the operation time but also the performance of the accumulator and of the system attached to the battery. One of the main procedures affected by the battery ageing is the determination of the state-of-charge. In this paper, a parameter called ageing...
A model is set up for a time-dependent description of currents, polarizations, state-of-charge and acid concentration with high spatial resolution in a flooded lead/acid battery. The detailed description of all relevant parameters for a battery under real operating conditions allows the use of results obtained under well-characterized laboratory conditions for different ageing effects. Models of...
