Smart Carbon is a proprietary Trojan formula which provides improved performance when the batteries operate in partial state of charge, or PSOC. This technology, according to Trojan Battery, enhances overall battery life in off-grid and unstable grid applications where the batteries are under charged on a regular basis. Trojan’s Smart Carbon proprietary formula also provides improved charge acceptance and faster recharge in PSOC applications, the company said.
According to Bryan Godber, senior vice president of global market development, Trojan Battery is the first manufacturer to introduce a carbon additive as a standard feature in its deep-cycle flooded batteries used in RE, inverter backup and telecom applications. "Trojan’s engineering team has spent more than five years in research and development experimenting with many types of carbon to ensure the right formula to successfully address PSOC,” he explained. “While most carbon additive research has focused on VRLA batteries for start-stop automotive applications, Trojan’s focus has been on the addition of carbon to deep-cycle flooded batteries for stationary applications in off-grid and unstable grid locations."
Batteries used in harsh RE, telecom and inverter backup systems are regularly cycled at PSOC due to the intermittency of solar generation, an unstable grid or to minimize operating costs of a hybrid charge-discharge-cycle (CDC) system. Operating at PSOC can quickly diminish the overall life of a lead acid battery, which results in frequent and costly battery replacements. With batteries now being one of the most expensive components of these systems, Trojan Battery believes it is critical to maximize the life of the battery bank in order to reduce total cost of ownership.
