WAE develops new off-highway electrification technology

Williams Advanced Engineering (WAE), a subsidiary of Fortescue Metals Group, is attending Bauma 2022, showcasing a range of electrification solutions, all of which will support the acceleration of the off-highway sector in its journey to decarbonization.

WAE used the event to show its battery and energy storage technology, specifically developed for the rugged use cases of mining and other off-highway applications. WAE says its technology line-up at Bauma 2022 includes:

Off-highway battery module – Featuring a scalable, modular design delivering sub-30-minute pack charge times for maximum performance, the off-highway battery module has laser-welded cell-to-busbar technology for in-service reliability. It also has a robust alloy frame, which the company says improves durability and extends life in service, as well as optimized cell packaging for maximum energy density.

Battery management unit – The battery management unit is designed for pack architectures of less than 800V. Its advanced state detection algorithms allow for more efficient energy usage, while the unit also reduces equipment downtime by enabling maximized fast charge rates.

Cell management unit – The cell management unit allows high-precision cell voltage and temperature monitoring by enabling real-time telematics to maximize cell performance. Its Flexi interconnects enable enhanced durability, while the system’s design also reduces manufacturing complexity for high-volume applications, the company says.

DC-DC converter – With a ruggedized design developed for deployment in off-highway vehicle applications, WAE says its DC-DC converter is a 600kW 1.5kV–1kV step-down converter for high power loads. Its Silicon Carbide (SiC) technology delivers exceptional efficiency of 98.5%, while full power operation takes place at an ambient temperature of 50 C (120 F).

Vehicle control module – The vehicle control module is specifically designed for decarbonized powertrains it has a flexible heterogenous MPSoC processor.
