MODULOWATT of fers a un iversa l so lut ion to the recharg ing of bat ter ies of EVs whi ls t they are

pa rked on t he pub l i c t ho rough fa re . The s t r a t egy i s based on t he f o l l ow ing f undamen t al i deas :

A hands free, automat ic, safe, one-size-f i ts- a l l recharging stat ion

Secured, month ly Di rect Debi t for park ing and recharg ing as wel l fu r ther serv ices that can be

prov ided

A bus iness model that guarantees the charg ing s tat ions operators an at t ract ive

return on investment thanks to revenue generated whi ls t the EV is parked

A redeployment so lut ion for EVs which can be used on a se l f -serv ice or

car-shar ing bas is

In essence MODULOWATT is a l l about an innovat ive approach to e lect ro-mobi l i t y . I t a ims to

fac i l i t a te the uptake of t he e lect r ic car in an u rban or per i -urban context in o rder to make i ts use

more widespread and to a fa r w ider audience.

BACKGROUNDINFORMATION_

SYNOPSIS

VISION& DETECTION

Th is operat ion requ i res:

An embedded, in f ra-red camera s i tuated in a cent ra l pos i t ion on the windscreen

(next to the rear v iew mir ror )

A t rack ing and image process ing system

A spec i f ic c i rcu i t located on the s ide of t he recharg ing s tat ion

(perpendicu lar to the f low of t ra f f ic of the veh ic le )

Fi gu re 1: Ar ch i tec tu re of th e de te ct ion sy st em

When the dr iver spots a f ree s tat ion (green l ight ) , he/sh e turns on the automat ic t rack ing dev ice.

The embedded camera then automat ica l l y searches ou t the nearest s ta t ion and fo l lows the s igna ls

g iven of f by LEDs.

Once the detect ion has been establ ished, the system, which can eva luate the d is tance between

the EV and the s tat ion, t hen sets to work to gu ide the veh ic le to the s tat ion s arm ex tens ion which

prov ides e lect r ic i t y for the recharg ing process. (The coupl ing and lock ing systems conform to

ex is t ing European standards). A spec i f ic a lgor i thm processes the in format ion rece ived and t ransmits

the resu l t t o the on-board computer wh ich then automat ica l ly leads the veh ic le to the des i red spot

(c f Contro l Pane l and Steer ing ) . Shou ld the system detect a f ree spot beh ind a veh ic le that is

a l ready be ing recharged the prog ram wi l l detect the t rack ing dev ice at the rear of the veh ic le and

wi l l fo l low the ident ica l p rocedure me nt ioned above.
