I hooked up a power-supply to my 120V pack once, backwards. The arc was bright, the bang was loud, leads were vaporized.

And we wont know till later tonight how I get the 3000 lb car up the hill to its hiding place… Don’t do this at home… But you ask, “But modern battery chargers will not charge a dead or reversed battery”… No, so I paralleled it with a jump-start battery to get it started… (Lead Acid batteries have the same LEAD on both the positive and negative terminals.

Growing carsharing company eases Comic-Con transportation woes
Transportation and parking can be major concerns for the
hundred-thousand-plus attendees of Comic-Con International: San Diego 2015.
car2go can ease those stresses. With its large fleet of electric cars and a
DropZone conveniently located near the Comic-Con campus, car2go provides a
great transportation option for San Diego residents and visitors alike.
Launched in 2011, car2go is the world’s largest and fastest-growing
carsharing company. With a San Diego fleet of 400 electric vehicles, car2go
allows members to use the one-way, point-to-point service to get to where
they need to go on their time and with ease. To make parking at Comic-Con
more convenient for its members, car2go will have a free parking area – or
DropZone – close to the San Diego Convention Center.
Memberships for San Diego residents or visitors coming to Comic-Con
available online at www.sandiego.car2go.com.
For the convenience of Comic-Con attendees, car2go’s DropZone with free
car2go parking is just a short 10 minute walk from all of the Comic-Con
action. Members can simply drive the car2go vehicle they’ve picked up to the
DropZone at 630 10th Avenue, check-in with the car2go team to end their trip
to go enjoy Comic-Con without wasting time looking for parking. The DropZone
will be open from 9:30 a.m. to 7 p.m. Thursday, Friday and Saturday of
Comic-Con; and from 9:30 a.m. to 5 p.m. Sunday.
This dynamic and accessible carsharing network will also provide Comic-Con
attendees a place to rest and recharge in the car2go Chill Zone. The Chill
Zone, located in the car2go office on 10th Avenue, will be open 11 a.m. to 6
p.m. Friday, July 10, and Saturday, July 11, offering free food and drinks,
a cell phone charging station, photo booth and even air conditioning for a
respite from the heat for its members. car2go members can visit the Chill
Zone for a break from the hustle and bustle of Comic-Con and to recharge,
both themselves and their electronic devices.
car2go is also a great option for San Diego residents any time. The service
simplifies spontaneous and planned commutes by providing members access to a
network of car2go vehicles within San Diego’s 33-square-mile Home Area,
allowing them to drive to destinations they want at times of their own
choosing for utmost convenience.. Members simply locate a car2go near them
via the company’s smartphone app, drive it to their destination, park the
vehicle and go about their day, leaving the vehicle for another member to
use. Members pay only for the time they use a car2go vehicle – just a $1
flat fee plus 41 cents per minute, which includes the cost of parking, gas,
insurance and vehicle maintenance. Company officials note that, in addition
to the fantastic convenience car2go provides, this car-sharing service is
also cheaper than many other alternatives.

Apparently I got confused because when I decided to close the loop with my multimeter set to Amps to verify how fast it would charge, there was a flash and a loud BANG... from shorting it across 600+VDC. I've had my share of educational moments as well. :-( This is an effective way to separate the cheap meters from the good ones. A good meter will have fuses and other protection to avoid just this sort of short circus (another Bob Rice-ism). So I have several damaged cheap meters... but my old Simpson 260 and Fluke 2010 have withstood everything I've done to them. On charging backwards: When a lead-acid battery is run totally dead, it becomes almost an open circuit. The electrolyte has turned to water, and the two plates are both lead sulfate. Connecting such a battery to its charger backwards will simply charge it in the reverse direction! What was the positive terminal becomes the negative terminal, and vice versa. But the battery works poorly this way. The plates aren't optimized to be used like this. If the battery is *not* dead when you connect a charger in reverse, the battery voltage and charger voltage fight it out. The charger says positive, but the battery shouts NEGATIVE! The battery is usually stronger, and wins. It *forces* the chargers's output voltage to the wrong polarity. This forward-biases all the rectifiers in the charger, and some enormous current flows. If the charger doesn't have an output fuse, then KABOOM goes your charger. This is why output fuses are pretty much mandatory in battery chargers. -- Where's the kaboom?

]
As public notices about law enforcement go, a recent announcement by Zero
Motorcycles barely registered on the world's attention meter. Still, the
electric bike maker felt obliged to tell the world it had 50 police
departments as clients for its zero-emissions motorcycles, a milestone that
bodes well for the green vehicles movement and air quality of a city near
you.
Looking at the marriage of electric vehicles and police work, you can see
why more cities around the country are giving their officers bikes and cars
that run on quiet EV technology rather than the rumbling cruisers and
Harleys of the past. Gone are the days when cops announcing their presence
is considered a tactical advantage. Fuel and vehicle budgets aren't what
they used to be, either, and bikes with over 175 miles of range are no
slouch in regular patrols.
In fact, the case for going gasoline-free in law enforcement is becoming too
strong to ignore. Here are five big reasons why electric motorcycles are
ideal for police work.
1. More versatility than gas bikes
Now that Zero Motorcycles has gotten the range of its fleet to respectable
levels (178 miles in its top model), you can begin to compare gas and
electric bikes on the rest of their merits. Both are capable of off-road or
city activity, but EVs have a big advantage of zero-tailpipe emissions. In
any indoor situations, cops can do their work without spreading fumes
through the room. Cleaner air is better for the officers and anyone else
they encounter during a day's work. Indoor pursuit on a Harley guarantees
the opposite experience.
2. Virtually silent pursuit
When longtime drivers first get inside an EV, the first thing they usually
notice is the near-silent operation. Electric motors are so quiet you barely
hear them coming. This feature gives cops a huge tactical advantage when
approaching perpetrators in any situation. Whether you want to deploy a few
bike cops to clear an area or hope to sneak up on suspects in a park
setting, these bikes are ideal for either purpose.
3. Cost of ownership
Any municipality hoping to cut operating costs should see what electric
vehicles offer with their lower cost of ownership. Between the
one-cent-per-mile price of fueling and the low maintenance of electric
powertrains (thanks to their few moving parts), cities and police
departments have a money-saving ally in these bikes. The same applies to the
pure EV and hybrid squad cars that are helping law enforcement agencies make
ends meet.
4. Emissions reductions
Between the versatility, cost savings, and other advantages, you might
forget how electric bikes reduce emissions dramatically when compared to
combustion engine vehicles. Governments from California to New York City
have pledged to keep driving down emissions for safer living, and these
bikes deliver on that front. Regular police patrols eat up way too much
gasoline as is.
5. Improved community relations
If you've ever had police racing through your neighborhood, you know what an
unpleasant ruckus cops can make doing their duty. The intense noise and
exhaust fumes are enough to make the most police-friendly communities get
annoyed at the boys in blue (or black, as the case may be). Getting officers
on electric bikes means eliminating the noise and tailpipe emissions, which
makes for better community relations. Judging by the news from the past few
years, there are many U.S. cities that could use a bump in that department.

Local repair shop owner charges into the automotive future
By Michelle Wagner June 29, 2015

Rich Brown plugs in his Ford Fusion (Energi pih)
]
Instead of heading to the gas pump to fill up, Rich Brown of Beach Ready
Auto Repair just reaches for a plug.
The owner a hybrid Ford Fusion [Energi pih] and an electric Volkswagen
Beetle [conversion] wanted to share his passion for electric vehicles. So he
installed an electric vehicle charging station at his Harbinger business.
The station is touted as the only one from the Virginia line to the Outer
Banks, Brown says, and his motivation for installing it is simple.
While the electric car's popularity may not have fully hit the Outer Banks
area yet, his hope is that it won't be long. And the charging station is his
way to get his customers talking — and thinking about owning an electric
vehicle.
Free to the public, the station provides a 220V@30 amps charge. Brown
eventually has his eye on providing the electricity via solar power.
The station was installed this spring and while Brown admits there haven't
been many users at the charging station, he hopes green travellers to the
Outer Banks will stop by to get a charge.
I've always been concerned about our dependency on foreign oil, and
electric cars are the way of the future, Brown says. The infrastructure
needs to be there and I want to do my tiny part. The more that people do,
the more it will take off. It is far better for the environment, and
cheaper.
His main purpose for installing the station, aside from charging his own
vehicles, is to bring awareness to the product. And, he admits, if the
electric vehicle movement took off one day, he may begin charging for the
service.
But right now it is 11 cents per kilowatt hours.
While the charging station may not generate a lot of users, it certainly
generates plenty of interest.
For people who don't know a whole lot about electric cars, when they see me
charging my vehicle and start asking questions, they may consider buying one
as their next vehicle.
Brown, originally from Europe where electric cars are extremely popular,
says that according to his charging station's computer, he has saved enough
carbon dioxide in just a few months to fill a hot air balloon.
A February report by cnsnews.com estimated that there are now just 286,390
plug-in vehicles on U.S. roadways. That's far less than the one million
President Obama predicted during his 2011 State of the Union address,
according to the Electric Drive Transportation Association.
But Brown says he hopes to do his part in this corner of North Carolina to
boost awareness of the potential of electric vehicles.
He's taken the first step with the charging station.

Not having enough texture to write about for an EV experience is a very good thing. So, in order to let you, my readers, know what is going on, and so you don't think I just fell off the edge of the earth, I thought that I might do a little revisit of some of the adventures that we have talked about in the past, and talk about where they stand now. Do you remember my adventure to the specialty grocery store that had items that I believed I couldn't live without? The first trip up was met with heavy winds blowing opposite to the direction I was going. I also had to contend with the highway speeds, everyone else seemed to be traveling on the Interstate making me a nuisance for trying to stay the speed limit or more accurately a nuisance to one idiot driver in the slow lane. It was also unseasonably cold that day, and my shoes were too tight, and my finger had a booboo, etc. etc. You get the picture. My range indicated by my Leaf dropped to below the miles needed to get back home when I got to the store. I was anxious whether I would make it home without needing to stop somewhere and get a charge. However, on my return the range changed dramatically where I ended up with something like 20 miles range when I got home. I wondered whether to put that store in my “safe to go without planning” file and then thought no. Well, that store is now firmly in the “don't need to think that much to go to it” file. I have been there several times with no problem. Why the difference? I used an online map to find the shortest route there trying to avoid that Interstate. I used another divided highway closer to my town that was built in anticipation of a bridge that hadn't been built yet. This meant a long, smooth road with little traffic on it, with plenty of room for faster going cars to go around me if they wanted. This only slightly shorter route also weaved through small suburban towns bringing my speeds lower following the advice of one of the commenters of an earlier posting. The weather has been cool, but not windy or unseasonably cold for all my trips there. To make this story shorter we have made it there with plenty of miles to return home and the return home is a breeze with plenty of miles to use for doing other stuff around town. I can now safely say that the specialty grocery store is no problem. The more I drive the vehicle and get used to the range the more adventurous I am becoming. I had once looked at a place that had a park along the river. In an earlier post I said something to the effect that I was glad that the park had a charging station so that I could go to it. Well, the station turned out to be at a dealer several miles away from the park, which constitutes “near” in distances in the country. The park, however, if I travel directly to it using the shortest route possible, was closer than I first calculated. Their is a flea market in the town nearby the park that I wanted to go to so I decided we should go and check it out. According to the online map the trip was going to be 25 miles out and 25 miles back leaving us with 30 plus miles to spare on our return. We went and the milage guesser said we had traveled 24 miles to get there. Pretty good. When we were set to return home my wife suggested we go to a restaurant in an out of the way town that featured fresh from the farm food. So we did. I didn't put it in the calculation of mileage, we just did it. I wasn't sure of the distance to the restaurant from the flea market, but I knew that the restaurant was about 15 miles from home. It made our trip, if mapped out from start to finish look like a bid capital D. We went pretty much straight to the flea market, then went along highway X to highway Y and down to the restaurant, then down on Y again till it reached a numbered highway and then to highway T until we reached county road K, which took us home. The trip ended up being longer than I thought and we pulled into the driveway at around 18 miles left in the range guesser, but no worries. What I am trying to say here is that after a while as an EV driver you develop a sort of sixth sense about range and where you can go and can't go. This trip wasn't planned out beyond the initial planning of how to get to the flea market. However, after the flea market the trip
