Gardena Lithium Battery

County Battery Services   have started to rebuild the Gardena Lithium Battery as you are probably aware lithium rebuilding can cause some difficulties however as you can see in the picture Stuart at our Nuthall Depot is an expert. If you need help with one of these or any other lithium battery pack please let me know. I can be contacted at County Battery Services

County Battery Services   use Panasonic cells for their power tool rebuilds the quality is second to none!

Taking old electric vehicle batteries and using them to store solar energy

Here is an interesting way to use a product that is no longer of serviceable use in the product that it was designed for then recycled to do another job The question is will it work?

Part of my work at County Battery Services Ltd is to look at new and innovative products that the Company can bring to Market some time ago we launched the Powerbank a device that captures the solar energy from photovoltaic cells and stores it to be used when the sun goes down.

Old batteries and solar I think this all sound a great idea, but in reality is it feasible? If the battery has come from a crashed damaged car that is an insurance total loss then I could see it working, but the suggestion is that you take a battery that is no longer of use in a car and expect it to perform in a solar application.

I am aware that studies are being carried out no one talks about the battery life after is has left the car, It would need to be reconditioned in some way or the correct voltage could not be maintained. When ever we have swapped cells in fork truck batteries the others soon start to fail not long after and they are of low voltage with typically no more than 24 cells

The battery could be dismantled and any faulty cells could be replaced but that is a time consuming and dangerous job (400V DC). As there are lots of cells in one of these packs It would be easy to miss some, or have others fail within days of the others being replaced. It is possibly cheaper to buy a new battery and definitely more reliable.

The quest to find a cheap way to store energy I think must carry on maybe a water tower and an Archimedes Screw would be better?

Alessandro Volta’s Born 18th February 1745. Inventor of the battery

In 1786 the whilst biologist Luigi Galvani was dissecting a frog. Each time his scalpel came into contact with the frogs leg it twitched. Galvani believed he had discovered a new kind of electricity and called it animal electricity.

Galvani’s friend Alessandro Volta disagreed he believed that the electricity was generated when two dissimilar metals were immersed in a liquid.Volta found in his experiments the most effective pair of dissimilar metals to produce electricity were zinc and silver.

He experimented with individual cells in series, each cell being a wine glass filled with brine into which the two electrodes were dipped. The voltaic pile replaced the goblets with cardboard soaked in brine.

In a letter dated March 20, 1800, addressed to Joseph Banks, who was the President of the Royal Society of London, Volta first reported the electric pile, allegedly the first electric battery,

if you want to know more about amp hours

100 Amp Fuller Leisure Battery

What are battery Ampere Hours?

Ampere hour or Ah is the amount of energy a battery can supply.

A typical leisure battery for the caravan market in the UK would be 110 ah at the 20 hour rate This means that the battery will supply 110 amps at a usable voltage over 20 hours (In this case we take a usable voltage to mean at load above 10.5 volts). To understand this further take 110 and divide by 20 the battery should be able to provide 5.5 amps continuously for 20 hours.

If you take a battery and the Ah value is measured over a different time period then the value will change because a 110 ah battery over 10 hours should be able to provide 11 amps continuously over 10 hours. It is very important that the hours rate is used when sizing any battery for this type of application.

The performance of a lead acid battery will decrease the faster the power is drawn from it.In a business like County Battery Services one of the most common mistakes people believe is that the 110 ah battery will deliver 110 amps for 1 hour this is NOT the case unless the battery is specified 100 ah at 1 hour rate

Beware some manufactures misquote their Ah capacity or do not give an hourly rating with it.A good indication of the battery quality is the weight. The main component part and the most expensive is the lead if you can remove some of the lead you save money.

 

 

BMW i3 The Electric Highway

In earlier editions of this blog I talked about charging well I have had my first experience of charging on the motorway. I had driven down to Luton Airport parked in Airparks and they charged the car for me for free. Charged at no charge is confusing!

Before I left I fully charged the car batteries but the outside temperature was below freezing and the lithium batteries like all the other batteries I have encountered with my work at County Battery Services don’t charge as well when cold. The reason for this is quite simple chemical energy converting to electrical energy and heat is the catalyst.

When I left the distance on the car said 92 miles and the sat nav said it was 111 to Luton. I pressed on and used the range extender for the extra milage. When I arrived back to Luton again it was really cold so I decided it was time to check out the charging on the M1.

The BMW has quite a good icon on the dashboard that tells you when it does not think there is enough charge in the battery to get you to your destination. When you click on it allows a search for charging stations along the route. I pulled into Leicester Forest East Services and just followed the instructions on the charger which involved downloading an app and adding my credit card details.

I was really surprised how fast the car charged I plugged in used the  convenience then went for a coffee before I had finished the coffee the app messaged me to tell me only five minutes to go! Within 30 minutes and £6 later my range was back up to 88 miles I felt refreshed it was good to stop.

I have two more blogs that link with this

Golden Week

Chinese National Day is celebrated on October 1st every year to commemorate the founding of the Peoples Republic of China. On that day lots of large scale activities are held nationally.  People use this time to take annual holidays and the seven day holiday is called Golden Week

Golden Week is from the 1st to 7th October and lots of Chinese people take vacations around China which makes traveling and booking hotels in China very difficult.

We at County Battery Services have traded with China for quite a long period of time and know how difficult it is to have any dealings during this week

We wish all our Chinese suppliers and customers a happy holiday for the forthcoming week
