As a part of the brand new challenge, which can run for 3 years till the top of September 2023, the consortium is now commissioning two electrified vehicles for subsequent common use by two logistics firms. Moreover, a battery alternate station is being developed in south Berlin for use by haulers as a part of their common supply operations. The purpose is to offer a totally automated battery alternate. Upon arrival on the station, the spent battery is faraway from the automobile by a specifically developed robotic and exchanged for a totally charged battery. This may all be achieved in a matter of minutes without having for time-consuming interruptions to cost batteries. “Each autos are fitted with quite a few sensors to file knowledge affecting power consumption throughout common operations: the power consumption of the engine, the load, the climate, the altitude profile of the route, secondary power consumption reminiscent of air con within the driver’s cabin in addition to the power required to keep up cargo maintain temperatures,” says Marker.
“In a real-life take a look at, we then wish to decide whether or not 40-ton electrical vehicles with exchangeable batteries are literally a viable various, together with when every day journeys of greater than 300 kilometers are concerned.
“Within the passenger automobile sector, battery electrical powertrains are at the moment gaining floor. This isn’t but the case to the identical extent for vehicles. Many vehicles drive distances of a number of hundred kilometers on daily basis, so we’d like an answer which nonetheless makes this potential. Battery electrical options must compete with different approaches, reminiscent of hydrogen expertise. “We’re inspecting the choice of battery alternate as it isn’t potential to maintain making larger batteries with out negatively affecting different consumption elements. Different choices embrace quick charging, which is already used for passenger automobiles. For vehicles, nonetheless, this may require a really excessive charging capability – in impact you would want to construct an influence station subsequent to the charging station – notably as common operations would require a number of vehicles to be charged concurrently,” Jerratsch explains.
One other drawback is that quick charging has a unfavorable influence on battery sturdiness. “Creating a community of alternate stations may present a viable various. Nonetheless, there are a variety of challenges concerned right here, too. We can be inspecting mount and bond batteries to vehicles to allow a quick and simple alternate,” says Jerratsch. In the long run, one other problem lies in standardizing exchangeable batteries in order to allow cost-effective, modular battery alternate on a bigger scale. Nonetheless, given the restricted variety of truck fashions, this represents much less of an issue than for passenger automobiles.
“Our work within the challenge additionally focuses on financial points in addition to technical and power consumption knowledge: develop a system that makes it potential to offer a cheap and actual various for the logistics department,” concludes Marker.
