Visedo – Electricity in Motion

Components and solutions for hybrid electric vehicles

Visedo business idea

Visedo® provides Electric drive trains for applications in

Buses (EV & HEV & LNG driven HEV)

Heavy mobile work machines

Marine vessels

Components needed for hybrid electric

Total Visedo® hybrid package

Fuel cells in hybrids

Fuell cell requirements to the system

Main Component changes in drivetrain:

1. Diesel engine+Generator is replaced by the

fuel cell packs

2. Inverter is replaced by the DC/DC-converter

3. Fuel tank is replaced by the H2 tanks

Notes about the fuel cell system:

• Some energy storage is still needed to ensure

dynamic response and to enable the

regeneration.

• Dynamic response time is in the range of

hunreds of milliseconds for the fuel cell.

• Results to a need of the DC/DC converter

between the main DC-link and fuel cell DC.

• System cost is today around 4 times higher

compared to the diesel engine based HEV

system.

Visedo® Hybrid – Enables the fuel cell

Future

• Visedo drivetrain can support

fuel cell based vehicles.

• Today cases with fuel cells

are limited to only few.

• Visedo prepares to support

customers using fuel cells by

testing the electric drivetrain

in real cases.

• The TEKES fuel cell program was a important part of the Visedo drivetrain technology

development.

• Efficiency of the components is the most important factor in electric drivetrain. Visedo

has the highest total drivetrain efficiency of the market today, over 85 %.

• VISEDO’s technology allow both full and hybrid electric vehicle designs by using same

electric drive train components.

• Already several customer references on electric and hybrid vehicles running!
