ALIVE will develop directly exploitable knowledge on materials and design concepts which offer a high potential for significantly reducing the weight of vehicles for affordable application to high productions volumes, focusing on next generation Electric Vehicles (EVs).
Specifically ALIVE has set a target of achieving a 30 % + 20 % weight reduction for the untrimmed vehicle body together with a 25 - 30 % weight reduction of the hang-on parts, chassis and main interior sub-systems. ALIVE strives to generate substantial, tangible innovation in terms of vehicle design, materials, forming & joining technologies, simulation & testing and includes an exceptionally ambitious physical validation activity that will not only deliver a full structural demonstrator of all modules addressed but which will also include destructive crash and durability testing executed on the assembled modules including the entire body.
Affordable weight reduction is one key factor for a more intensive market introduction of electric vehicles. For an EV with 200 km range (and with battery capacity of 200 – 300 Wh/kg) the allowable costs of weight saving would be round 8 €/kg [ECK10]. For above mentioned 8 €/kg (= 10 $/kg) more than 40 % of lightweighting seem to be obtainable [HOF12].
However, further weight reduction leads to an exponential cost increase. Avoiding such cost increase is the main challenge of the ALIVE project.
