Case Study #1 : CONTAINER FORKLIFT

APPLICATION :

A brand new Hybrid Drive Train has been developed by Dimac Red in collaboration with an Italian container

forklifts manufacturer for a 15-ton machine

TARGET :

Reduction of machine size and weight

Reduction of consumption

Homologation costs cut down

Performance matching or improvement

compared to standard machine

Confidential

SOLUTION :

To downsize the diesel engine ICE, a SuperCapacitor storage has been connected to the DC-Bus, allowing

to reach optimal performance during lifting and traction operations.

The ICE works close to its maximum efficiency point, supplying an almost continuous power to the net, while

the SuperCapacitor provides the peak power.

Case Study #1 : CONTAINER FORKLIFT

TARGET ACHIEVED :

ICE size reduced FROM 5.0L to 3.0L

Overall machine weight reduction of 10%

Homologation and certification costs reduced, as the new

machine has a lower class than the previous one, despite

lifting capability of 15 tons is kept

Fuel consumption reduced by 50%

Payback time 1.5 year

Case Study #2 : HYBRID COMMERCIAL VEHICLE

APPLICATION :

Development of a SuperCapacitor based storage system to be connected in the hybrid power train of a light

commercial vehicle. Aim is to support peak power demand during hard acceleration and braking phases.

TARGET :

Increase of performance during vehicle

acceleration and braking

Vehicle autonomy extension

Weight reduction

Ni-NaCl battery lifetime increase

Confidential

SOLUTION :

Downsizing the Ni-NaCl battery storage, adding a SuperCapacitor storage connected to the DC-Bus through

a Supercapacitor Management Interface – SMI.

The ICE and the battery storage work on a low-power rating, allowing fuel saving and increasing possible

route length. Vehicle start and stop cycle is managed through SuperCapacitor high-current charge and

discharge dynamics.

Case Study #3 : SPORT CAR START&STOP

APPLICATION :

Development of Start&Stop system for automotive industry. Due to Start&Stop regulations, bigger and

heavier lead acid batteries are needed to achieve performance required.

TARGET :

Reduction of on-board storage size and

weight

Cold cranking

Voltage stabilization

High reliability

Confidential

SOLUTION :

To add a SuperCapacitor storage connected to the 12V net. Supercapacitor has extremely high power

density and low weight, in order to manage the engine cranking.

A reduced lead-acid battery can be installed, to support low power to auxiliary vehicle load, such as

electronics, lightning, pumps …

Stand alone SuperCapacitor or fully integrated hybrid lead acid and SuperCap are developed.
