| Abstract |
Hybridisation of the power is now a challenge for the 5 following years. Due to the necessity of
optimising the size and the weight of all the devices, a theoretical study of the 3 main energy storage
(batteries, supercaps and flywheel) shall be realised. This study shall include a technical but also an
economic approach depending on the architecture of the vehicle, its life cycle...
The main conclusion is that the flywheels present now a lack of power, the supercaps a lack of energy.
As for batteries, an objective of a large number of charge discharge cycles i.e. a long lifetime reduces
strongly their performances to a low percentage of their theoretical capacities.
But to justify the utilisation of an energy storage, the economic aspect are important and often
dissuasive. |
