As this yr’s System E season attracts to an in depth, electrive interviewed Dirk Kesselgruber, the Chief Know-how Officer at GKN Automotive, who offered an outlook on the place the corporate’s expertise stands, and the place it’s heading.
Followers of the electrical racing sequence will know that the technical necessities change from season to season, with a view to accommodate the technical improvement within the business, in addition to to maintain the races themselves aggressive and charming for the viewers. One main such innovation would be the addition of charging stops subsequent season, which the rivals needed to plan round this yr. Because of this, power conservation and recuperation performed a serious position, whereas subsequent yr’s charging capability could take the next precedence in technical improvement wants.
Nonetheless, the flexibility to recharge a battery isn’t the one requirement for competing within the race, as Kesselgruber explains, efficiency weight and consumption play a far greater position, as they primarily decide the automotive’s vary, velocity and acceleration capacities. As such, complexity and redundancies must be downscaled, with a view to make the autos extra environment friendly. A useful gizmo on this space shall be digitalising and simulating the autos, their drives and even their manufacturing services.
Dirk Kesselgruber factors out that this efficiency enchancment can be simply translatable to the general public automotive market, the place phrases equivalent to ‘vary anxiousness’ are nonetheless typically heard within the discipline of electromobility. Applied sciences equivalent to thermal administration are additionally on the desk for optimisation, which performs a deceptively massive position in EV driving and charging expertise. Kesselgruber added that rethinking processes to scale back complexity and drive down prices is important, as they’re rising as a serious barrier to e-mobility adoption reasonably than automobile ranges. GKN goals to do that by optimising outdated processes and rethinking the event strategy from new angles.
GKN has taken a considerably decentralised improvement strategy to fixing these points, with improvement labs around the globe, which every look to their very own market specs, however share many technical developments, equivalent to software program and mechatronics. GKN additionally desires to develop its personal efficiency electronics, seeking to enhance efficiency and decrease improvement and manufacturing prices.
Kesselgruber defined that this may necessitate the event of extra rational programs, coupled with balancing prices and efficiency, in addition to making an attempt to save lots of area and weight within the newer system iterations. Different processes require rethinking the place the , rethinking processes to combine or presumably even save steps may maintain the important thing. Volkswagen’s PowerCo, for instance, is following this strategy with its dry coating course of for battery cells, eliminating the necessity for an energy-intensive drying course of.
Platform voltage foundation performs a serious position for driving quick or hauling heavy
Kesselgruber additionally factors to 800-volt expertise as a significant component within the development of energy and charging capacities of electrical drive programs, for which he factors to Germany being a world chief. Whether or not this lead will stay as the present German authorities is doing little to help technological innovation and German producers complain in regards to the lack of orders, each at residence and internationally, stays to be seen. Regardless, the 800-volt platform does permit for increased efficiency and quicker charging, however whether or not that is one thing that is smart for broad use on public roads is one other query totally, notably as charging infrastructure is changing into more and more widespread and accessible. Final yr, GKN offered their most up-to-date era of inverter expertise for 800-volt autos.
For autos equivalent to electrical vehicles, or buses, this is able to additionally make lots of sense, because the autos have a bigger battery to cost and are in additional fixed use than private autos. In response to Dirk Kesselgruber, GKN shall be trying on the downside from a number of angles, with a number of analysis objectives. By splitting their analysis groups far overseas, they’ll every compartmentalise particular person approaches to expertise, whereas sharing the outcomes with the remainder of the corporate.
Significantly as e-mobility is leaving its child sneakers behind, extra approaches to expertise improvement shall be wanted. Not all autos profit from bigger batteries, however nearly all of them do profit from weight financial savings, as this requires extra power to speed up. Elements equivalent to thermal administration additionally play an enormous position: battery optimisation with out cooling or heating the unit, relying on climate situations, is sort of unattainable, and saving weight on this space would profit principally all electrical autos.
Future objectives
As talked about above, the following season of System E is deliberate to function charging stops, which is able to change the necessities for the racing autos considerably. That is additionally paralleled by the regular growth of charging infrastructure in the actual world: notably for the reason that extra widespread adoption of Tesla’s NACS charging expertise, producers have began displaying extra curiosity in charging networks. For instance, even within the USA, a brand new automotive alliance is forming to create a brand new high-power charging community on the continent with help from BMW, Common Motors, Honda, Hyundai, Kia, Mercedes-Benz and Stellantis. Tesla additionally began putting in its new V4 Superchargers in Europe just lately.
