EnerSys has extended its class-leading Hawker XFC range with two new models, including its first concept design with advanced lithium-ion technology for the motive power sector. Both are designed for low-duty pallet truck applications where operators want to maintain equipment availability without the complexity and cost of additional infrastructure. They can be recharged at any time irrespective of the state of charge without degrading their long-term performance or reliability. Both have an on-board charger and are ideal for applications with duty cycles lasting up to 45 minutes where periods of inactivity can be used for rapid opportunity charging. This makes them suitable for intermittent or sporadic handling requirements such as offloading delivery vehicles or replenishing displays in busy retail environments.
The Hawker XFC-Li is the first motive power battery concept from EnerSys to utilise advanced lithium-ion technology. This 24V battery with 38Ah capacity incorporates cells with a lithium iron phosphate (LiFePO4) cathode and graphite anode with an inherently safe lithium-ion electrolyte. This delivers significant benefits compared with conventional units including greater power density, longer pack life and excellent performance at low temperatures. The battery can be fully recharged in less than one hour from 80% depth of discharge and short, opportunity charges are readily accepted due to its very low internal resistance.
The second new battery is a 24V model with 82Ah capacity based on the same proven thin plate pure lead (TPPL) technology used in the existing Hawker XFC range. Its blocs incorporate pure lead plates which are much thinner than conventional lead calcium grids. These have lower impedance which enables higher current flows in recharge and discharge modes. The electrolyte is absorbed in a superior quality microporous glass mat separator with high absorption and stability for enhanced cyclic capability. These attributes ensure full recharges can be completed in under three hours from 60% depth of discharge.
Both models are supplied with a high frequency charger integrated into the top compartment of the battery tray. High-frequency charging ensures the batteries consume less energy, with resultant lower electricity costs, and have a smaller carbon footprint than conventional units. The batteries are totally maintenance free and require no topping-up with water for low overall cost of ownership while minimum gassing means they can be used in confined spaces and public areas.
