Hybridization requires energy storage elements even for the first steps like micro-hybrids. The level of hybridization determines directly the energy storage solution. Furthermore, the energy storage solution influences strongly the global cost of the system. For electrical vehicles, the cost of the battery exceeds 70 % of the hybridization costs. This fact has pushed the choice of Valeo to offer a intermediate micro-mild solution based on ultra-capacitors in order to optimize the costs of the system. |
