Electricity evolution in Automotive
•  Electricity is one of the most evoluting technology in automotive
•  An attractive technology to provide: Energy, Control & Diagnose
•  It strongly participates in the feature race, about:
Uptime, Reliability, Requirements & Profit
•  1 Missed engine start:
500€, ~30 minutes, 1 missed ferry
1 missed contract?
A bad Start…. to End a business!
•  A good reason be in balanced technology phase
Not to early. Neither to late: Just in time
Lead or Follow?

Vehicles:
Some few µ-controlers and mixed parts of the AV.
Voice:
Was used to talk and sing.
Displays:
CRT in colour, LCD/Plasma/EL mono-colour.
Electrification: Discrete wires
Wireless?:
AV-Remote controls.
WiFi was still a free acronym,
and Harald Bluetooth was still just a Viking

ICE η: 0-45% x: ~30%
