German based trailer and vehicle manufacturer TII Scheuerle has introduced a battery electric power pack unit (ePPU) for its SPMT self-propelled modular transporter range, compatible with all generation two to four axle lines.
The new unit provides the same performance as the company's most powerful diesel Z390 power pack, capable of operating up to 26 driven pendulum axles or 40 conventional axle lines. The lithium ion battery pack provides sufficient power for a full working day's operation, with recharging from 20 to 80 percent possible in under 30 minutes using a 300kW CCS power plug, or overnight with a 44kW AC connection.

The electric motor delivers maximum torque immediately for improved starting performance and traction compared to diesel units. The company says the system is up to four times more energy efficient than diesel engines, with lower maintenance requirements due to fewer moving parts.
The ePPU is designed for zero emission operation in enclosed spaces such as tunnels, while offering lower noise levels than diesel powered units. The company says this makes it particularly suitable for use in urban areas or indoor applications.
