EV Batteries?- How Cheap Are they really? Climate Denial Crock of the Week

Home » general motors

I’m finding Chevy Volt replacement ev batteries online for about $2,300. $2,300/16 kWh = $144/kWh. Retail. On the GM Parts Store site a replacement battery for the 2012 Chevy Volt is listed at $2,305.88.

Eric Roberts‘s insight:

Why a replacement ev batteries any how ?

EV batteries prices

This article shows the prices for the  EV Batteries replacement but I was wondering why would you need a replacement anyhow?

According this good and in depth article a replacement battery would cost $2000 and more, but why would you have to buy one? The old  EV Batteries should be replaced free of charge if found faulty, like any other part of the car. Some of the European car makers, such as Renault, lease the batteries out when they sell an Electric Car, so I can only assume that the same warranty reasons will apply to them.

In my opinion, when the EV batteries will need replacing in a few years’ time, then the technology that is carried out at the moment will have drastically reduced the battery prices by that time. All this new development will probably reduce the size of the batteries, to a more realistic and affordable size. Johnson controls are developing a Lithium-Ion battery at the moment that is much smaller than its predecessors.

 

 

The only reason I can think of for an EV car to need  new EV Batteries, is after an accident.

 

Because of the battery power train size there is likely to be damage caused by an accident. This brings me to the cars insurance, is the possible scenario of a crashed EV car requiring an expensive battery going to put insurance premiums, or will the cost be spread amongst us all?

There is no doubt that the EV car will play a significant part in the future of fuel efficient cat technology, with batteries that can last for years due to the advent of silicon “Nano” battery technology and car manufacturers will keep up with these improvement trends.

The charging rates are also getting much better, with charging time expected to get down to as low as 15 minutes for an 80% charge but my money is still on Hydrogen cell technology. However, this is a good article and worth a click to read.

Volvo self driving cars- 100 to be tested on Swedish roads in pilot project …

Volvo self driving cars

Volvo has announced a pilot project that’ll see 100 Volvo self driving cars take to the roads of Gothenburg, Sweden, as the automaker continues in its efforts to bring a fully autonomous self driving cars to the market.

 

Eric Roberts‘s insight:

Volvo self driving cars

Hi it must be a strange feeling to get into a car that can steer and drive to its destination without any aid by a driver. I must be getting old ,because I can’t see for the life in me what these Volvo self driving cars are going to gain.

If that’s what people want why on earth don’t they stick to the driver- less train systems that we see in many countries these days? I would much prefer to sit on a train high up above the busy traffic “Than In Volvo self driving cars”. Significantly, modern technology is good, but it is not perfect. I recently visited France and had to turn off the motorway because it was blocked by an accident, a large truck had toppled over, completely blocking the two lane motorway.

Unfortunately, we had to turn off so I switched on my satellite navigation system, hoping to pick the motorway up further North. I keyed in Calais further North and the sat/nav kindly to me to three junctions South of the junction that I had to turn off on? It then came up with a server problem message, which rendered it useless?.

So I have my doubts about the technology used in these cars.

Here is a good snippet from the Popular Mechanics web-site about the strange sensation that their driver experienced when first handling one of these Volvo self driving cars,

“As soon as I hit the small black lane-centre button, I can feel the wheel stiffen in my hands. Suddenly the light bar atop it begins to glow a soft green, signaling that the car has taken over the task of steering. I had already surrendered control of the acceleration and braking to the vehicle’s adaptive cruise control, and now with my feet flat on the floor, I slowly un-wrap my fingers and release the wheel. Sitting in the passenger seat is Jeremy Salinger, who works on General Motors’ semi-autonomous car program. He’s seen the car do this dozens, possibly hundreds, of times, but, if only to reassure me, he states the obvious: “The car is in control now.”… http://www.popularmechanics.com/cars/news/industry/the-12-most-important-questions-about-self-driving-cars-16016418

His final comment is that” it felt like a ghost was driving the car”

UPS Batteries Have Many Uses-12 Volt 12 Amp are very popular

Home » general motors

UPS Batteries Have Many Uses; 12 volt 12 amp in most backup batteries supply systems ?

I would not be exaggerating to say that that the 12 volts 12 amp UPS  (uninterrupted power supply) battery. Will be found in most large offices around the World. The most common usage for this one is as a backup supply source of power. Of course, in the event of a mains power supply failure. When the mains go down. Then the 12 volts 12 amp battery bank kicks in and allows the computers to carry out a proper shutdown. So, saving very valuable data from being destroyed. The UPS battery will be used in very large banks of backup systems .

These UPS Batteries Have Many Uses. Including, backup systems will usually come within a surge circuitry. Also have a built in filter this will protect the circuits and the computer from power surges. These surges are known as transients, spikes and surges and can destroy and even delete data as well as damaging the computer equipment. One of the commonest forms of power surges is lightening, even if an adjacent building is struck then a surge can occur and damage an unprotected computer system, but thanks to the 12 volts 12 amp battery then this will be protected.

For further reading…

“Even entry-level battery backups provide visual and audible alarms based on various states of alert. They also include automatic shutdown software that controls the connected microcomputer via USB port so that if the user happens to be away from the computer when the power fails, the system takes over and initiates safe shutdown procedures before they drain”… http://battery-backup-review.toptenreviews.com/what-exactly-is-a-computer-battery-backup-and-which-one-is-best-.html.

 12 volt 12 amp batteries also fit many mobility scooters

This 12 volts 12 amp is also now used to power some smaller mobility scooters. As a result, it takes 2 these 12 volts 12 amps to make a 24-volt system . UPS Batteries Have Many Uses and here is some very important information about the care of your 12 volts 12 amps when they are not in use and during the winter months from an excellent website called www.easymedonline.com…

 Always store your batteries FULLY CHARGED.

– Check all batteries once a month and recharge as needed.
– Wet ones can hold their charge up to 3 months.
– Sealed ones can hold a charge for up to 6 months.
– When storing a chair or scooter for more than 2 weeks, charge them and then disconnect them.
– Avoid hot and cold extremes when storing.

What is the proper way to store batteries for the Winter?

A: Store them fully charged. Check them once a month and recharge as needed. Sealed ones can hold their charge from 6 to 12 months. Remember, if storing your chair for longer than a couple of weeks, it’s best to charge them up  and then disconnect them”…http://www.easymedonline.com/more/batteries.html
