Electric vehicle and battery laboratory
Description: VTT has increased the operations in its vehicle laboratory in Espoo, Finland, to meet the development needs of electric vehicles. The new power supply unit mounted is capable of both simulating the battery system of a heavy electric vehicle and performing full-scale battery chargedischarge cycles. In addition, a totally new battery laboratory was opened in September 2012. It concentrates on measuring the performance of battery cells, modules, and complete energy storage systems for electric vehicles in a repeatable manner under variable controlled circumstances for different standardised and application-specific duty cycles. Electric vehicles and their powertrain can be studied in both laboratories jointly as an entity, including electric motors, electronics and batteries.
Static Equipment
Battery testing equipment
Description: Equipment for various testing of batteries. Circumstances like temperatures and charging profiles can be adjusted.
MultiPower
Description: MultiPower is a national empirical research environment where new technical solutions and products for distributed energy system can be tested in a multifunctional environment. There are several independent testing facilities connected together so that the environment may cover production, control and loading concepts. Research infrastructure for DER and other testing activities at VTT is called MultiPower system. The unit fromm MultiPower 100 kVA can be connected in parallel with a 1,6 MVA diesel generator and up to 1,7 MW resistor load into an internal island network. Connection to 20 kV network is possible, loading up to 200 kVA. The 1,6 MVA generator will act as a rigid network to which the other generating or consuming e. g. 100 kVA units can be synchronized.
