  • Three mtu EnergyPacks support sustainable and ultra-fast EV-charging at three Shell Recharge stations in Singapore
  • mtu systems enable integration of electricity from renewable sources
  • Over 130 mtu EnergyPacks in use worldwide

Rolls-Royce has supplied three mtu EnergyPacks to system integrator Eigen Energy in Singapore. The compact battery containers ensure sustainable and ultra-fast charging of electric vehicles at three Shell service stations in Singapore. Shell recharge is using electricity from 100% certified renewable sources locally, including the solar panels at the rooftop of these stations. With a power capability of 180 kilowatts per charging station, these e-filling stations are the fastest publicly available in service stations in Singapore. Depending on the vehicle model, a typical 30kWh charging session at these three service stations can now be completed in less than 15 minutes.

With the help of the battery containers, electricity from photovoltaic systems is integrated into the energy system, which serves to reduce the CO2 footprint while also offsetting peak electricity loads. During periods of low utilization by the service stations, the system feeds remaining electricity into the public power grid. The consortium around Eigen Energy and Rolls-Royce’s business unit Power Systems designed and built the battery storage units to meet special safety precautions due to their proximity to the refueling station within the city.

Benefits for e-mobility providers: ultra-fast charging, lower electricity costs

E-mobility can cause local grid constraints: If several vehicles charge in parallel at a fast-charging point, the demand for electrical energy increases rapidly and at short notice. Using an advanced control system, the mtu EnergetIQ, mtu battery storage systems can help prevent temporary load peaks with the corresponding high electricity costs and support ultra-fast charging power. The control system recognizes when the energy is needed for charging or when it can be fed into the grid, and also manages the influx of power from regenerative energies such as PV. Rolls-Royce has already supplied mtu EnergyPacks for around ten e-charging projects, including for energy company Verbund in Austria, Stadtwerke Münster, which uses them to power its e-bus fleet, and project development company Abowind.

Over 130 mtu EnergyPacks in use worldwide by industry, hospitals, hotels, mines and utilities

Rolls-Royce offers various battery storage solutions: The mtu EnergyPacks QS and QL are produced as container compact versions (slightly smaller than 10 feet) and as 40-foot containers partly at the company's own plant in Ruhstorf, Bavaria. They range from 200 kVA to 2,000 kVA power and from 312 kWh to 2,084 kWh storage capacity. They are also scalable to be flexibly adapted to customer requirements. The large-scale storage solution mtu EnergyPack QG also offers individual configuration options from 4,400 kVA and 8,900 kWh with scalable capacities up to several hundred megawatt hours. In addition to the lithium-ion battery modules, the mtu EnergyPacks contain inverters, cooling equipment and the intelligent control system mtu EnergetIQ, making them complete storage solutions.

Battery storage is a core component of microgrids that deliver grid independent power, but is also integrated into solar parks for grid stabilization, for example, and is used for energy trading or the charging infrastructure for e-mobility. More than 130 mtu EnergyPacks from Rolls-Royce are already in use worldwide in industry, hospitals, hotels, mines and at energy suppliers.
