Alpine 100% electrical A110 E-ternité prototype debuts at French Method 1 Grand Prix; batteries fore and aft

The 100% electrical A110 E-ternité prototype had its world premiere on the French Method 1 Grand Prix. A rolling laboratory, the A110 E-ternité is an open-top automotive which maintains Alpine’s agility with a lightness unequalled for an electrical automotive on this section.

The design aim was to affect the A110 and to match the efficiency, stability and agility of the Alpine A110 combustion engine automotive whereas capitalizing on the Group’s strengths, expertise and applied sciences.

As a Renault Group model, it was pure for this new mission, to look first on the elements and applied sciences already obtainable in-house. The battery modules are similar to these of the 100% electrical Mégane E-Tech. Nonetheless, to attain optimum weight distribution and to accommodate the twelve battery modules, it was essential to design particular battery casings for the A110 and to adapt the interior structure.

4 modules had been subsequently positioned on the entrance and eight on the rear. To satisfy this problem, the engineers allowed themselves to place these modules within the area in a atypical style.

Regardless of the addition of those twelve modules, the full weight of the Alpine A110 E-ternité stays notably gentle with a rise of solely 258 kg, because of a contained mass for the battery pack (392 kg).

Gearbox. With a view to get away from the 0 to 100km/h / prime pace trade-off and the fixed quest for electrical storage that requires giant batteries, an modern gearbox was added to the Group’s “normal” motor.

No gearbox obtainable in-house allowed the Alpine engineers to fulfill the temporary necessities of this A110 E-ternité. The need was to discover a easy and environment friendly gearbox with out torque breakage, but in addition gentle and compact.

A gearbox was studied in-house, with the Alpine gearbox provider, in double clutch model (DCT) with an digital management, as on the A110 combustion engine, however with clutches dimensioned to go excessive torques. The double clutch resolution makes it doable to keep away from a break in torque whereas remaining compact and lightweight.

Digital system. For the digital system, the Alpine crew combined two digital tools architectures separated by ten years. This innovation gives new alternatives for structure simplification or steady enchancment all through the product because it enabled the options of the combustion engine AS1 to be saved whereas including new options from the EV sector, in addition to others such because the “Overtake” function or the opportunity of enabling communication between two batteries.

A single ECU was put in to make sure communication between the 2 techniques. This innovation brings new alternatives for simplifying architectures or for steady enchancment all through the product life cycle.
