K-VEC project goalsRealization of a pure EV with the following specs:
Autonomy can be moved from the vehicle to the territory (road infrastructure)
K-vec prototype Technology target values
Vehicle autonomy (km) 1-2 1-10
Charging time 40”- 60” 10”- 20”
On-vehicle energy storagesystem LCA
----Improvement compared to
standard pure EV
Overall costs (investments +operational)
----Reduction, compared to
standard pure EV
Charging system Automatic
Braking energy recovery > 95%
Deployability in urban context In sub-urban context

K-VEC project's contribution to the Key dimension objectives
1. Socio economic issues
- Energy savings in EV transport;- Cost reduction in EVs that will increase social acceptability - Increasing deployment of EVs within current transportation systems.
2. Technological strategies
- Low cost recharging infrastructure for EM, deployable on several types of vehicles
- A boost of ITC applied to transportation: K-VEC implies a fully controlled two-ways com link between vehicle(s) and stops.
- A thoroughly new system concept of energy and power management on an EV, validated by the main public patent offices (US, CAN, EU,...).
