Chennai: At Ashok Leyland, a group of near 100 engineers have picked Newton’s second legislation of movement, F = ma (Pressure is the same as mass instances acceleration), because the North star for its engineering actions. The legislation, in easy language, signifies that the acceleration of an object /mass is immediately proportional to the web drive utilized on it. These efforts are underway, as a part of a ‘Newton Truck’ idea, an concept which bought mooted with Ashok Leyland’s seventy fifth yr milestone final August.
“We try to assume very otherwise, and due to this fact innovate from basic ideas,” Dr. Kanakasabapathi Subramanian, Sr. VP, Superior Engineering, Ashok Leyland, tells ETAuto. For starters, the engineering group’s key objective is to not develop an extra know-how for a truck, however to innovate methods to boost its vitality effectivity. “If you happen to have a look at the info, it really reveals that not a really giant proportion of the battery energy is definitely wanted to drive the (electrical)car. And there are numerous inefficiencies in an vehicle,” says Dr. Subramanian.Subsequently, the important thing activity for the engineers is to cut back the inefficiencies, together with what are generally known as ‘parasitic losses’ in a car, however in methods which haven’t been tried but. Decreasing air resistance by means of 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 might contribute wherever between 20 to 60% of the vitality losses. Any profitable efforts will yield advantages for each ICE and electrical automobiles, however the advantages could also be extra pronounced within the latter class.
Decreasing rolling resistance of tyres is without doubt one of the key targets to attain within the Newton Vehicles challenge. Ashok Leyland finds that rolling resistance “a really massive loss mechanism”, and it’s “in all probability the largest in electrical automobiles”. “You’ll be able to work on how effectively you employ the battery to show the wheel, that to us really is wanting like a extra attention-grabbing strategy to resolve the issue,” says Dr. Subramanian, who provides that the group is engaged on some concepts which, if profitable, could be shared with the tyre suppliers.
The battery pack is the one costliest part in an electrical car. Provided that the home EV ecosystem continues to be within the making, radical improvements within the trade might additionally imply lesser dependence on imported content material in EVs. Vital discount in tyre roll resistance, and related enhancements which cut back vitality consumption may very well be a “fairly massive knob” to cut back the import dependence, whereas additionally lowering the inherent inefficiencies of an vehicle. “And, (it) may very well 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 standard objective. A special method than Within the bigger engineering and R&D organisation, the place there could also be disparate concepts taking form, and getting carried out 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 standard objective. A special method than Within the bigger engineering and R&D group, the place there could also be disparate concepts taking form, and getting carried out in numerous methods. The final word goal for the Newton Truck Challenge group is to come back as near Nature’s ideas of physics. “What Nature supposed was, if you did not have losses you might drive with out gas. That sounds a bit loopy, nevertheless it’s true. I am not saying we will drive (an vehicle) with out gas, however use the least quantity of gas, 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 group 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 “most probably” become involved with the modern concepts, at the very least for a few of them, as soon as they obtain feasibility.
