Electric vehicle offers powerful acceleration

Posted by Staff writer

The Tecnalia Technological Corporation has built a totally electric car that can reach 140 kilometers per hour in 10 seconds.

The two-seater car is based on a single-shell, rigid, lightweight chassis of steel and aluminium alloy, with an adjustable deformable parallelogram suspension system for the four wheels.

It has a peak power of 100kW provided by a permanent magnet synchronous electric motor, a total weight of 700kg and an energy storage capacity of 15kWh.

It's been built to allow the installation of a battery or small internal combustion engine to extend its range - around 70km at present.

Acceleration from 0 to 100kmh is under 5.7 seconds, and peak speed is approximately 140kmh, reaching this figure in 10 seconds.

The vehicle will be adapted to run on the open road, but its main application is to act as a research platform for new concepts.
Technologies under development include high-powered electric traction, as well as systems that take advantage of new propulsion systems, such as boost vectorisation or distributed traction.

"The electrification of road transport is one of the priorities of the research, given that the dependence on fossil fuels and the greenhouse effect has focused everyone’s attention on the traditional concept of transport, based on vehicles with conventional motor drive," say the researchers.
