Since 01 April 2019 we have been offering a battery system with new battery design and a charging station with a fan and a control unit. The special design allows active and passive cooling. This reduces the cooling time of the batteries in heavy-duty shift operation in the event of temperature problems. The battery tray has DIN external dimensions (DIN A tray 50070) and is constructed according to a safe tray-in-tray concept. The special intercooler cells are optimised for high current discharges. Therefore our customers achieve longer operating times with the trak | intercooler than with conventional batteries of the same capacity. Furthermore, the battery system is equipped with HOPPECKE trak | air and trak | aquafill for efficient charging and simple maintenance.
