Our solution: a technology that allows you to convert traditional cars into plug-in hybrid-solar vehicles

How is composed

• In the rear wheels two electric motors are integrated that transform the car into a 4×4 hybrid drive (conventional traction on the front wheels and electric on the rear wheels)
• The electric motors are powered by an additional lithium battery mounted in the boot (instead of the “wheel”). The battery can be recharged by solar panels, by the vehicle itself (during braking or descents, or by absorbing the additional torque generated by the engine in order to optimize the overall performance), or by the network (Plug-In option)
• High-performance flexible solar panels (produced by Solbian, partner of the LIFE-SAVE project), are mounted on the roof and on the bonnet of the car, with the function of recharging the vehicle’s battery, both during driving and during the phases parking, free and without CO2 emissions
• A control system, connected to a display, drives the electric motors based on the requests of the driver and the state of charge of the battery, connecting to the vehicle through the OBD port, normally used for diagnostics, and without interfering with the control unit of original vehicle check

The advantages

• The internal combustion heat engine works less, because part of the power required for traction is provided by electric motors, and this translates into lower fuel consumption and lower emissions of polluting gases. The benefit can reach 20-25% for a typical use in urban areas (one hour of driving a day) and on sunny days, but it is still appreciable even in the absence of sun, for the benefits related to hybridization (recovery of the braking energy and downhill, optimization of the efficiency of the thermal engine)
• The car, now comparable to a hybrid in terms of fuel consumption and emissions, can have access to restricted traffic areas (ZTL), where it can move in a predominantly electric mode
• Unlike what happens with an electric car, the car has no recharging and autonomy problems, which on the contrary is also increased compared to the traditional vehicle of departure due to the presence of the additional battery
• Compared to the starting car, the car will perform better thanks to all-wheel drive. In particular, the presence of two electric motors in the rear wheels gives better capacity during acceleration, which translates into a reduction of more than 20% of the time to go from 0 to 100 km/h
