Chennai: At Ashok Leyland, a staff of near 100 engineers have picked Newton’s second legislation of movement, F = ma (Drive is the same as mass instances acceleration), because the North star for its engineering actions. The legislation, in easy language, implies that the acceleration of an object /mass is instantly proportional to the online power utilized on it. These efforts are underway, as a part of a ‘Newton Truck’ idea, an concept which received mooted with Ashok Leyland’s seventy fifth 12 months milestone final August.
“We try to suppose very otherwise, and subsequently innovate from elementary rules,” Dr. Kanakasabapathi Subramanian, Sr. VP, Superior Engineering, Ashok Leyland, tells ETAuto. For starters, the engineering staff’s key purpose is to not develop an extra expertise for a truck, however to innovate methods to boost its vitality effectivity. “If you happen to take a look at the info, it really reveals that not a really giant share of the battery energy is definitely wanted to drive the (electrical)car. And there are plenty of inefficiencies in an car,” says Dr. Subramanian.Due to this fact, the important thing job for the engineers is to scale back the inefficiencies, together with what are often called ‘parasitic losses’ in a car, however in methods which haven’t been tried but. Lowering air resistance by higher aerodynamics, friction discount all over the place the place it occurs, are the important thing ones. Relying on the way in which a car is pushed, these may contribute wherever between 20 to 60% of the vitality losses. Any profitable efforts will yield advantages for each ICE and electrical autos, however the advantages could also be extra pronounced within the latter class.
Lowering rolling resistance of tyres is likely one of the key targets to attain within the Newton Vehicles undertaking. Ashok Leyland finds that rolling resistance “a really huge loss mechanism”, and it’s “most likely the largest in electrical autos”. “You may work on how effectively you utilize the battery to show the wheel, that to us really is wanting like a extra attention-grabbing solution to clear up the issue,” says Dr. Subramanian, who provides that the staff is engaged on some concepts which, if profitable, can be shared with the tyre suppliers.
The battery pack is the one most costly part in an electrical car. Provided that the home EV ecosystem continues to be within the making, radical improvements within the business may additionally imply lesser dependence on imported content material in EVs. Important discount in tyre roll resistance, and comparable enhancements which cut back vitality consumption might be a “fairly huge knob” to scale back the import dependence, whereas additionally decreasing the inherent inefficiencies of an car. “And, (it) might be a giant deal for India,” says Dr. Subramanian.
‘Within the Newton Truck Challenge, the area of interest groups are working to mix collectively a set of various concepts, with a typical purpose. A distinct strategy than Within the bigger engineering and R&D organisation, the place there could also be disparate concepts taking form, and getting applied in numerous methods.’.
Within the Newton Truck Challenge, the area of interest groups are working to mix collectively a set of various concepts, with a typical purpose. A distinct strategy than Within the bigger engineering and R&D staff, the place there could also be disparate concepts taking form, and getting applied in numerous methods. The last word goal for the Newton Truck Challenge staff is to return as near Nature’s rules of physics. “What Nature meant was, if you did not have losses you can drive with out gasoline. That sounds a little bit loopy, nevertheless it’s true. I am not saying we will drive (an car) with out gasoline, however use the least quantity of gasoline, by engaged on (containing) losses, as an alternative of engaged on the battery measurement or stuff like that,” says Dr. Subramanian.

Because the superior engineering staff works on addressing the losses, Dr. Subramanian says it’s not going to attend to unravel all of the losses after which implement them, however “as we make progress, we’ll (implement) wherever commercially possible”. And, on this journey, the seller ecosystem would additionally “probably” get entangled with the modern concepts, no less than for a few of them, as soon as they obtain feasibility.
