IAV is once again present on the joint Decentralized Energy Supply booth (Hall 27, booths J50 and M70). Besides the micro-CHP unit and the IAV Energy Container, the engineering company is also presenting its expertise as a consultant in a wide range of energy matters. Whether complex computations for electricity and gas grids, control concepts for wind power systems or developing hydrogen technologies – IAV uses its vast wealth of specialized knowledge from automotive engineering and applies it to the energy sector with tremendous success. “For IAV, decentralized energy supply and renewable energies are themes that extend our development portfolio. We have the expertise across the entire system in these areas too”, says Kurt Blumenröder, President and CEO at IAV.
Micro-CHP unit engineered in-house
In the past, IAV has already demonstrated that the company is capable of developing components for miniature combined heat and power units. Its engineers have now developed a full micro-CHP unit entirely in-house, and are presenting a prototype of it at the booth. In engineering the micro-CHP unit, the focus was on quality and cost-efficiency. Benefiting from cutting-edge test-bench technology, IAV was in a position to conduct all tests and acceptance inspections on its own.
The micro-CHP unit is configured for use in single or two-family houses. It comprises a three-cylinder 1-liter industrial engine and, using an asynchronous generator, delivers up to 5 kW of electrical power and 13 kW of thermal energy. It can run on natural gas well as liquefied petroleum gas. Measuring 70 cm (W) x 90 cm (L) x 130 cm (H) and weighing approx. 200 kg, the power plant is extremely compact and can be moved and fitted into virtually any utility room. The control system is a new design, with the control cabinet (50 cm (W) x 50 cm (H) x 20 cm (D)) containing the power and control module. The micro-CHP unit can be operated from a conventional tablet, smartphone or laptop.
Clean energy everywhere – the IAV Energy Container
At Hannover Messe, IAV is also presenting a prototype of the second-generation energy container to a broad audience. Among other modifications, the latest generation comes with innovative battery technology. The IAV Energy Container provides a peak output of 9.6 kWp from sunlight alone – and can do so across the globe without any pollutant emissions. The underlying idea is to produce clean electricity – also at places not connected to the grid. The version of the energy container on display at the show also features a water treatment system from cooperation partner FaribaTec, a system that generates potable water from waste water and process water. FaribaTec is already closely involved with relief organizations, like Bread for the World – Protestant Development Service.
These containers can be used in development cooperation, disaster relief and energy supply for treating water or supplying off-grid transmitter masts. The energy can be buffered in the innovative accumulators; it can also be fed directly into a grid.
The IAV Energy Container is equipped with a 9.6 kWp monocrystalline solar power generator and an optional small 3.5 kWp wind turbine with a hub height of 18 m as well as an emergency diesel generator. The off-grid power inverters provide a 3-phase system with an output of 15 kW. The container is suitable for on-grid, off-grid or combined mini-grid applications.
