Perfecting the pairing: Designing the truck-trailer combo

| November 18, 2013

The tractor will have one deep-cycle battery for electrical needs while driving. It also will have an Engine Start Module, which is an ultracapacitor used only for starting. This reduces overall weight and space requirements and ensures that the truck starts in all conditions, no matter how low the other batteries have been drained.

Combining these technologies with the proven technologies in the first- and second-generation units will add significant fuel mileage increases and lower lifetime maintenance costs.

    Some of us were doing this 10 years ago. 4 extra truck battery’s under the bunk, and a 2500 watt inverter in the sleeper did a very good job maintaining the temperature as long as it was between 30 and 90 degrees. Got a little warm in the dead of summer, but we saved a lot of fuel shutting down all but 10 or 12 nights a year. Slept better and had tv and video games too. No worry about running the starting batteries dead with a fridge or xbox ether. Small free standing air conditioner behind the passenger seat, two 12 volt heaters in the bunk. A webasto would have been even better, but considering I only had 400 bucks in the whole system, that was not an option.
