IMICS Power System

The IMICS (Integrated Magnetic Interface Charging System) is fixed to the drive shaft of a truck and through our patent pending design, uses the different rotation points as part of our integrated generator. Currently, it is able to power lift gates, on-board electric pallet jacks, reefer units, and other electric and hybrid units. The IMICS is not regenerative braking but charges the auxiliary system batteries continuously as the truck is in motion. The IMICS system is able to provide a range of voltages and amp output. Currently, we can charge battery systems from 12-48 volts and provide amp output from 23 to 220 amp hour.

The solution consists of the IMICS power generator, control unit, and battery. The entire system itself is essentially bolt-on, similar to APU units, utilizing all industry standard mounting interfaces and power connections. It has no belts or mechanical interfaces, no gears, no brushes. With no parts that will need replacing, the system is virtually maintenance free. And unlike other non-motorized, on demand power solutions, it does not require in-wall, “overnight” charging. The GRE Solution can therefore be a quick and complete replacement of any existing auxiliary battery or APU charging system. 

The IMICS system is installed onto the truck similar to other auxiliary systems and applications. The control unit and battery are attached to the frame and secured in a NEMA 4 enclosure. The power generator is mounted around the driveshaft of the truck, and is bolted to the undercarriage at a carrier bearing mount point.

Magnetic flux is the only resistance or drag between the power unit and driveshaft, as the power unit is not in direct contact with the driveshaft. There is zero mechanical interface with the IMICS system.

TAG System

The TAG (Trailer Auxiliary Generator) system developed by Green Road Energy, was designed to provide a true charging platform for any auxiliary power need on semi trailers, and to do it in a way that benefits not only the companies using it, but also the environment.

The TAG system is designed to provide a charging source to batteries for lift-gates, motorized pallet movers, lights, pumps, etc. Basically, any auxiliary power demand on a trailer can be supplied by the TAG system.  The patent pending system (US # 63/054,379) is designed to be installed under the trailer making the entire charging process contained to the trailer. There is no connection to the cab needed. If a customer has a traditional charging system with a cab connections, it can be connected to the TAG system and the TAG can charge from both systems. 

The TAG system is set up to provide a charge for a 12 volt battery bank, at up to a 50 amp input. With other battery charging systems currently on the market, it’s not uncommon to see 14 amp input as best case. With the TAG system mounted on the trailer in close proximity to the battery box, there is no voltage drop due to long distances/run of charging cables. This means that the batteries are receiving the correct voltage when being charged. The TAG system, designed as a horizontal-axis wind turbine, allows for the wind that is developed as the truck and trailer are moving through the air, to be captured by the high-solidity blade which spins the generator. The generator is setup to start outputting at extremely low rpm, which generates the electricity that is sent to the batteries.

The control module monitors the voltage of the batteries, and once the voltage reaches the preset volt level, it diverts the energy to a built in “dump load” to ensure the batteries are never over charged. When the voltage of the batteries drops to the low voltage set point, the controller will again route the energy to the batteries, charging them. The control module and rectifier are located in a NEMA 4 enclosure which is attached to the frame of the TAG unit.

The TAG system has been able to start generating/charging at speeds as slow as 9 MPH. In testing, ( perfect conditions & setup) the TAG system was able to charge a 12 volt battery from 12.3 volts to 13.7 volts in 6.9 miles, and displayed a settled charge of 12.5 volts.  This included both city and highway speeds over the testing distance. While this was in a controlled environment, this can change depending on the length/type of trailer as well as position or angle at which the TAG system is installed.

With no belts or brushes to replace, no fitting to grease, the maintenance on the TAG system is minimal. The suggested daily maintenance is a visual inspection to ensure no debris has attached to the intake screen

For customers who require a larger amp output, or 24, 48 voltage, the TAG system can be customized for a specific demand. In any case, customers who use the TAG system can expect to find that their lift gates batteries are continually charged. This in turn will ensure the driver has a working lift-gate, motorized pallet jack, or pump, making each delivery safer and faster.

As no idle mandates are becoming the norm, companies using Green Road Energy’s TAG system will find themselves ahead of the mandate as their drivers will not have a need to idle to power their systems. This results in the reduction of the use of diesel fuel which will save fuel costs across the fleet. That in turn provides a ROI (return on investment) of just under 3 years at current diesel prices. Companies find that their carbon footprint is also reduced as idling is not needed. This allows companies to be one step closer to being ISO 9001 compliant.
