Huber Automotive AG, an established specialist in the field of automotive electronics and e-drive systems from Muehlhausen near Stuttgart, presents, with its optimised version of the RUN-E Electric Cruiser, an emission-free power package especially for mining applications. Just as the original it is designed for use in extreme environments, but the electrified version of the Toyota Land Cruiser J7 ensures improved air quality, reduced noise pollution and operating costs savings underground.
The E-drive system consists of series components from well-known suppliers such as Bosch, all arranged in a new architecture in order to optimally integrate the individual characteristic strengths. Made possible by the core of the system: an innovative control unit from Huber Automotive AG, which, based on a 32-bit power architecture, causes the individual components to perform at their best under ideal thermal conditions. The central vehicle control system of the automotive supplier integrates all system-relevant components, regulates the energy management of the high- and low-voltage system and coordinates brake energy recovery depending on the driving situation as well as the charging and safety management.
Moreover, it monitors all control and regulation processes with regard to functional safety. The latest update to the already successful E-Drive Kit uses a new battery with a capacity of 35 kWh and high recuperation capability, specially developed for heavy-duty use. The additional customising for mine operations ensures that the certified and homologated battery is particularly safe and robust. Crash tested, waterproof and housed in a fireproof case, the new battery has extensive sensor technology, including carbon dioxide and humidity sensors. As a control level it supports an intelligent thermal runway warning and protection system to provide the best possible safety – especially underground. This system operates at both module and cell level, including partial automatic shutdown, to guarantee early warning in the event of irregularities and to prevent self-ignition and total failure in case of small short circuits. The powerful battery not only operates safely but also efficiently and guarantees a range of up to 150 km on the road and 80 – 100 km off-road.
The Run-E Electric Cruiser has an output of 90 kW with a maximum torque of 1410 Nm. Speeds of up to 130 km/h are possible on road, and up to 35 km/h on off-road terrain with a 15% gradient. In its standard version, it can handle gradients of up to 45%, and with the ‘high-off-road’ option it achieves the theoretical value of 95%. Additional packages, such as battery cooling or heating and an air conditioning system, allow the electric car to be adapted to the individual conditions of each mine, including warm feet with optional air conditioning for the passenger compartment.
The electric version enables completely pollution-free driving and, thanks to cleaner air, lower vehicle heat load and less noise pollution due to the silent electric motor, enormously improves the health protection of employees, especially in mining and underground mining. At the same time, the operating costs for maintenance, operating materials and ventilation are significantly reduced for operators.
