Caterpillar has called the system Cat Dynamic Energy Transfer (DET), which is suitable for the intermediate charging of both battery-only and hybrid mining vehicles. The solution consists of a power module that converts energy from a mining site’s power source for charging the electric trucks, a rail system for dynamic charging, and the aforementioned transfer arms that are attached to the vehicles.
The rail system is mobile and, according to the developers, can be adapted to the customer’s specific mine layouts. The connecting arm can also be flexibly installed on both sides of a lorry and on different truck models. Caterpillar explains that the charging rail means that a mining truck can even be charged while driving up a steep incline, which increases the vehicle’s uptime and operational efficiency. Caterpillar recently presented the solution at MINExpo 2024 in Las Vegas.
