Battery maker Trojan claims its new proprietary ‘Smart Carbon’ technology can improve the cycle life of lead acid batteries by as much as 15%, through effective management of the cell in a partial state of charge.
The company, which has been in business since the 1925, produces lead acid batteries for use at various scales. It claims that its new products are particularly suitable for use in partial state of charging (PSOC) applications, such as those involving PV and where grids are backed up by diesel generators.

PV Tech spoke to Trojan’s senior applications engineer for renewable energy, Kalyan Jana at the Intersolar Europe show in Munich. Jana explained that while lead acid batteries are still cheaper and more readily available than more modern technologies such as lithium-ion, the need to optimise battery performance is much more acute when you have a lead acid battery being only partially charged and then discharged.
