My dual battery setup works decently on my Silverado pickup truck for producing camp power for use under the truck cap. For the first night at camp, it provides more then enough power at night, including lots of lights, alarm clock, and moderate use of a portable fan, and 90 watt laptop charger.
After the first night, the deep cycle battery starts to wear down. The inverter will show lower and lower voltage, until it starts beeping every 15 seconds, and eventually shuts off at around 11 volts, to protect the battery. Yet, it can be continued to be run, all you have to do is turn on the engine, and let the truck run at idle speed for like 10 minutes, every 1-4 hours, depending on how heavy your electrical load is. I used an average of 1/3 gallon of fuel for every night after the first night parked, without driving.
As the battery is isolated from the starting battery, running the deep cycle down to the point where the inverter shuts it off is not a big deal. Your starting battery is still fully charged, and the deep cycle will after all get recharged as soon as truck restarts, and the inverter prevents you from going below 10.9-11 volts, a point where damage can occur, even with a good deep cycle.
For most moderate lighting demands — let’s say 75-100 watts — enough to run a couple 26 watt florecents, your pretty close to the 4 hours. But when you start adding a laptop charger or fan, and after the third day without the truck moving, you start to drop things down closer to once an hour. Reducing the load when charging, also helps the truck charge faster, as does swapping out the 60 amp fuse between the batteries with a 100 amp fuse, to send any excess amperage to the deep cycle as fast as possible.
The system originally came with a 80 amp fuse, but I cracked that fuse, when I was re-tightening the connections on fuse holders. Apparently, the fuse holder between the deep cycle battery and the starting battery was loose, and on the bumps of dirt roads would become disconnected. While ultimately, I fixed it by retightening the connections, I ended up breaking the 80 amp fuse, and could only get a 60 amp fuse locally. I plan to buy a 100 amp fuse over the internet at some point.
I rarely stay in the same campsite more then one night, at least without driving somewheres in the truck. Even relatively short periods of charging the battery at above idle speed, e.g. driving rapidly increases the rate of charge. It does however use much more fuel to drive the truck then staying idled.
One of the consistent thoughts I’ve had in recent months — both before and after buying Big Red — is Big Red-era coming to an end? Big Red, as those who regularly read my blog know is my Chevy Silverado pickup truck, which is my big truck, and primarily my toy for camping.
Gas prices are up big time this summer. They are significantly higher then a five or ten years ago. Some analysis suggest that gas prices will only continue to increase, as global petroleum stockpiles decrease — especially the easiest sources of petroleum are tapped. Some peak oil folks are almost in a panic.
At the same time, the signs of Climate Change are becoming more pronounced. We have had a record warm spring time this year, with record temperatures being smashed throughout the spring. We have also seen increasingly violent weather touching many parts of country in the past year.
There are those who advocate more conservation now. We should immediately all take steps to reduce our climate footprint. Indeed, one of the reasons I take public transit around time, is to reduce my carbon footprint (plus driving in town is so annoying).
Yet, I have to ask, why did they get to have their fun when they were young, driving Mustangs and other Big, Fast, and Powerful Cars. while I don’t? Their response is we didn’t know better back then, even though they should have known better.
I thought some Excel spreadsheets might be of use to you. Obviously, there is a lot besides the cost of gasoline in owning an automobile, but we as a society have a fixation on gas prices, and they seem to effect out behavior a lot.
The Cost to Drive calculator can help you with specific trips.
Commuting is a big consumer of time in people’s lives. For every ten minutes added to a person’s daily commute, each way, takes 43 hours per year out of a person’s life, that could be spent doing other activities. Moreover, as most people commute by private automobile, time spent in cars, is time not doing physical exercise or getting outdoors, promoting obesity and poor health.
From this map of Albany County, you would think rural people all have long commutes to work. Indeed, people who live in Renselearville, where there are few jobs, often commute to downtown Albany, leading to a very long commutes, that are particularly challenging in the winter.
However, that is not the norm in NY State. Indeed, the Adirondack Mountains, have some of the shortest commutes in the state. Residents of the North Country and Southern Tier also have very short commutes. Many work in the small towns they reside in, or farm the land they live on.
Also of interest is that commutes, in general are much shorter upstate then downstate. In some areas — like Albany — commutes from suburban areas to jobs are shorter then in more urban areas, due to the use of private automobiles over mass transit.
As much as I despise air pollution, noise from the cars, wrecked landscapes from where they drive, I really do like cars.
Nothing speaks freedom like the open road. Nothing expresses your personality and who you are like your car. Nothing can bring you such beauty as the automobile or bring you just great experiences.
From the dirt road in the Adirondack Forest Preserve to an open rural highway in the Northern Tier, nothing can quite bring you their like an automobile.
My particular passion is pickup trucks. The bigger the better. The better the 4×4 system, the more room in the cab, the more room in the bed, the more lovely.
Yet, I am well aware of the problems of automobiles, and especially their uses of in urban areas. I walked along Washington Avenue Extension, as a pedestrian, and I was a aghast at their noise, pollution, and swarming motions they made.
Automobiles make urban areas ghastly places to be.
There are too many automobiles in the city. Off the beaten track, in Rural America, they truly are wonderful things.
Automobiles destroy cities, but they are also the best way to get away from the cities.
Sure a car will rust and decay, fall apart, and be another junker. One might say it’s a waste of money.
When cars are not being driven solely for pleasure, they are the most miserable beasts, forcing one to follow extreme restrictions and control measures, doing nothing but forcing us to labor for meaningless waste.
I’ve always wondered what the fascination with battery technology is, when the proven technology used by trolleys and streetcars for over 120 years is electricity via rail or wire. There are no limitations on range or power delivered electrified lines, and use avoid the inefficiency of power stored in a battery.
I could envision the car of a future being a gasoline engine with complete cylinder deactivation, where the complete engine is shut off by a solenoid disconnecting the rocker arms controlling the valves ala the Active Fuel Management widely used in General Motors pickup trucks today.
On major highways and other high traffic roads where “electric wires” are available, as sensed by a radio signal, the car would automatically pop up trolley poles through the roof like a power radio antenna. Electric consumption and billing information would be transmitted through a signal in the wire to the billing municipality, public authority, or power company.
An electric motor/generator in the transmission of the car would spin the drive train and engine, including pushing up and down engine pistons (using the exhaust in the cylinders and shut valves as a choosen) and flywheel. When braking or going downhill, the motor acting as a generator would put recovered power back into the electric line.
The nice thing about this system is there is no range or weight limitation, and uses existing technologies. You could power even semi-trucks or buses with this technology. Moreover, if you become disconnected temporarily from the electric line, the motion of engine’s pistons decompressing the exhaust left in the cylinders and the standard flywheel, would keep the car coasting until electricity came back or the solenoids reconnected the push-rods to the rocker arm and started feeding the engine gasoline once again (the later could happen basically instantly if there is such a power demand).
Because your still moving the pistons up and end down and compressing waste gases, the engine never gets cold, always has warm coolant to heat the inside of the car, and is always ready to burn gasoline at proper operating temperature whenever electricity is dropped.
I can not imagine a future where cars don’t have at least some kind of internal combustion engine that burns gasoline or diesel, at least part of the time. We have been refining Internal Combustion Engines for 110 years now, and the technology is so well engineered and reliable, that it seems likely that cars will use Internal Combustion Technology of some sort for at least another 110 years, if not longer. Internal Combustion Engines are only going to be come cleaner and less polluting as pollution control standards and technology improves, and they are only going to burn less gas or diesel in decades to come.
