At the seventh edition of Expoelectric, held on 11 and 12 November at the Arc de Triomf in Barcelona, the public saw the electric vehicles developed by the teams ePowered Racing and e-Tech Racing from the Barcelona East School of Engineering (EEBE); UPC ecoRacing and MotoSpirit from the Terrassa School of Industrial, Aerospace and Audiovisual Engineering (ESEIAAT); and ETSEIB Motorsport and eRide ETSEIB from the Barcelona School of Industrial Engineering (ETSEIB).

Expoelectric  is the largest event involving electric vehicles and efficient technologies. It aims to bring electric vehicles closer to the public and is a showcase of the latest energy-saving technologies developed by the main engine brands on the market.

e-Powered Racing
The 20 students in the e-Powered Racing team have already completed their first 100% electric prototype. EPR00 is a motorcycle that uses a commercial chassis as the basis for developing the entire electrical system and creating a functional vehicle.

Last summer, the team carried out several tests at the Zuera international karting circuit in Zaragoza in order to study the bike’s functionality and continue preparing the prototype for future competitions. In fact, the team plans to compete with universities from all over the world for the first time at MotoStudent, which will hold its fifth edition in October 2018 at the Motorland circuit in Aragon.

e-Tech Racing
Stev-e is the third single-seater of the e-Tech Racing team. Like the previous ones, it is an electric car that shows the team’s commitment to sustainable mobility. It is powered by two independently controlled motors using a torque vectoring algorithm, a system that allows cars to control how the wheels receive energy. In addition, the students will develop their own engines for the first time and will incorporate a full aerodynamic package of carbon fibre and a tubular chassis.

Last summer, the e-Tech Racing team competed with Stev-e at Formula Student Spain, where it won second place at the national level in the Skidpad trial. Formula Student is an international competition held in different countries for which university students design, build and compete with a single-seater vehicle. In the Formula Student Czech Republic, also held during the summer of 2017, the students won second place in the Cost Report, the test that evaluates the manufacturing processes used to build the vehicle.

UPC ecoRacing
This season, the electric single-seater racing car ecoRZ 2017 shows the team’s commitment to sustainability with its 100% recyclable body (unique in racing), and its recyclable multi-tubular steel chassis.

The new vehicle incorporates improved hybrid carbon fibre and aluminium wheels, which help reduce the vehicle’s weight. Improvements in the design and the engine have allowed ecoRZ 2017 to reduce the lap time and give it an efficiency of 87%, twice that of a conventional car.

At last summer’s Formula Student Spain, the single-seater once again beat the acceleration record for a rear-wheel-drive car and is now placed thirteenth in the world ranking among more than 1,000 teams. This marks an end to the season that began for the ESEIAAT students in December 2016 with the victory in Formula SAE Australasia, held in Melbourne.

MotoSpirit
The MotoSpirit team have developed a 100% electric motorcycle with the electric motor provided for the international MotoStudent competition, for which the students have to design the batteries, frame, transmission, suspensions and fairing.

They are currently working on the prototype for 2018, taking into account the aspects developed in 2016. Their main aim is to optimise the battery for the MotoStudent competition. So far, they have finished the conceptual design and are working on the detailed design.

With the 2016 prototype, the team obtained first place in the MS2 category at MotoStudent. In this stage, the prototypes competed in a series of dynamic tests and races to demonstrate their performance and dynamic capabilities. In addition, the team came second in the general classification of the competition.

ETSEIB Motorsport
With CAT10e, their tenth car (the sixth electric one), the ETSEIB Motorsport team have achieved the best results since they started participating in Formula Student.

In the 2017 Formula Student Spain, the team received the Prize for the Best Team in Spain and came ninth in the general classification. In addition, CAT10e closed the season with second place for the Cost Report and third place for the Business Plan at the Barcelona-Catalunya Circuit.

Previously, in Formula Student Austria, CAT10e came first in the Cost Report and ninth in the general classification. In addition, the team came seventh in the general classification of Formula Student Germany, the best result achieved by a Spanish team. It also received the Best Prepared Car for Scrutineering Special Award and came first in the Cost Report.

e-Ride ETSEIB
The e-Ride ETSEIB team are currently designing their new prototype for a 100% electric motorcycle, which they presented at Expoelectric. They will compete with this vehicle for the first time at MotoStudent Electric in October 2018 at the Motorland circuit in Aragon, where the prototypes will be subjected to acceleration tests, races and an examination of the business plan.

The new prototype will have six times more power, more than twice the voltage, and a battery of more than 100 V powering the prototype’s motor, with a rated power of 12 kW.

Last year, the eRide ETSEIB team won the Best Dynamic Events, Best Static Events, Best Acceleration and Best Overall Position categories in the Smart Moto Challenge competition with the TRO police motorcycle.

Expoelectric
Expoelectric is an initiative promoted by the Generalitat of Catalonia through the Catalan Institute of Energy (ICAEN), the Barcelona City Council, the Barcelona Provincial Council, the Association of Technical Industrial Engineers of Barcelona (ENGINYERS BCN) and the Metropolitan Area of Barcelona.

The objective of the event, which this year was in its seventh edition, was to present zero-emission vehicles and related technology to the public. Leisure activities, talks and stands are used to raise awareness and to disseminate and promote energy saving and efficiency.
