TPPL batteries have up to 10% more energy content than flooded lead-acid batteries and up to 20% more than Gel VRLA types. This is achieved by the higher number of plates and reduced plate thickness. However, it is the flexible and rapid charging ability that separates this battery class from other lead-acid alternatives.
The Logistics Point September 2020
TPPL technology allows Partial State of Charge (PSoC) cycling without compromising on battery life. A cycle life of 1500 at 60% depth of discharge (DoD) is possible and even more at shallow DoD.
With opportunity charging, trucks can complete an entire shift or even longer without losing time for recharging. Fast charging is also possible with charge rate from 0.25C5 to 0.4C5. The combination of charging speed and increased battery capacity allows truck fleets to operate with fewer batteries, thus supporting a lowe TCO. The NexSys Core battery using TPPL technology is also available in an ATEX (ATmosphères EXplosives) version that allows materials handling vehicles to work safely in hazardous areas where there is an explosion risk.
TPPL battery technology with carbon addition
The NexSys Pure battery builds on the TPPL base with added carbon in the active material. The chemical changes in the battery yield improved performance in terms of lower internal resistance and higher charge acceptance. The NexSys Pure battery delivers ultra-fast recharge and exceptional PsoC cycling performance.
TPPL batteries with carbon added have high specific power and can sustain up to 160% energy throughput per day. This means that batteries can last for 2 to 3 shifts using multiple opportunity charges. Addition of carbon in the active material formulation and the use of a dedicated charging profile improves a NexSys Pure battery’s life, up to 50% more than NexSys Core battery (depending on application and use). This battery can outlast the rental contract for most trucks. As a bonus, disposing of TPPL batteries with carbon is profitable compared to the extra costs to dispose of Li-ion.
