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.
