Nottingham looks to optimise EVs with new system

Open source internet of things (IoT) technology is set to help Nottingham to optimise its electric vehicle (EV) fleet as part of a pilot project.

On 18 January, OpenRemote announced that Nottingham is developing an intelligent energy management system (iEMS) for its Clean Mobil Energy project using its open source IoT platform. The new solution will control the distribution of power between all parts of the system, which include an EV fleet, battery storage and solar power. It will enable the city’s energy managers to maximise use of locally produced renewable energy, cut carbon emissions and reduce costs that stem from charging EVs.

The pilot site at Eastcroft Depot is set to combine three main elements, solar panels to generate power, a large lithium-ion battery for storage and a 40-strong EV fleet. Vehicle-to-grid (V2G) technology will allow for the EVs to be charged and discharged for operational purposes, while also allowing for short-term energy storage and grid balancing.

The city’s energy managers will have an energy dashboard provide them with continued insight into the performance of each element, allowing key performance indicators, such as local energy, self-consumption and saved costs, to be monitored. A mobile app will also allow energy managers or maintenance crew to assess the system performance “on the go”. As for management of the EV fleet, the iEMs will be able to establish optimum charging schedules based on parameters such as lowest cost or highest share of renewable energy. EVs will be charged to their minimum mileage, or beyond in instances of surplus green electricity or low tariffs. The system also enables fleet managers to define minimum mileage per fleet and offers insights into the day-to-day operations, performance and total energy use of each group of vehicles.
