A single lithium-ion 18650 cell is relatively small in size and in capacity. So how does Tesla pack 85,000 W.h in the battery pack of the Tesla Model S? The answer is very carefully. The battery pack in a Tesla S is a very sophisticated assembly of several thousands...
The cost of today’s lithium ion battery constitutes a very large fraction of the total cost of electric vehicles, and a very visible portion of the total BOM (bill of materials) cost for a mobile device. It is estimated that the battery pack for a Chevy Volt costs nearly...
That is of a rechargeable lithium-ion battery, of course….We all know that lead-acid batteries, the type you have under your hood, tend to be of a standard size, but lithium-ion batteries can come in a multitude of packaging and shapes. One of the most common...
There is a little icon on a top corner of your mobile device that reads a percentage value corresponding to the fraction that your battery is full — this fraction is known as state of charge (SoC). The little charge measurement instrument is embedded in the mobile device...
By now you are familiar with the limitations of a rechargeable lithium-ion battery. There are three parameters that I have covered so far that describe the general performance of a lithium-ion battery. They are energy density (which dictates capacity), charge rate...
You probably suspected that temperature swings are not good for your lithium-ion battery. But what is the extent of the damage, and what are the temperature limits that one should attempt to follow? This is the subject of today’s post. If you were to review a specification...
I wrote in a previous post that the standard for a dead battery — at which point it should be replaced — is 80% of its original capacity as a newly manufactured battery. Why is that? Is this a random value or is it based on a valid rationale? At the surface of it...
I am an avid photographer. I have been one for a long time. My first camera was vintage ca. 1968. Its body was simple. It had a mechanical shutter; no battery; no metering; no autofocus….but I was proud of the lenses that I accumulated over the years; I labored...
The new iPad Air 2 is a beauty, isn’t it? At 6.1 mm thick, it is nearly feather light. The new iPhone 6 is 6.9 mm. The Android competition is not far behind. The race to make ultra thin smartphones and tablets is on. Thin is in…but certainly not easy! One very important design...
My prior posts are begging for today’s post: “Mirror, mirror on the wall, who’s the fastest of them all?” Yes, you guessed it right, not all mobile smartphones are created, ehem, designed equally. Yes, some are designed in Cupertino, others in Taipei or Tokyo or Seoul...
Samsung recently announced their new Note 4 with a claim that it charges from zero to 50% in thirty-ish minutes. What is thirty-ish? Is it 31 or 39? Motorola also announced that their newest Moto X will provide 6 hours of mixed use after only 15 minutes of charge. Mixed...
Charging your mobile device’s battery was pretty much a non-issue for many years…customers seldom complained; manufacturers did not see charging as a limitation; and charging, well, was really not a problem. That began to change in the past year or two...
You own the newest smartphone model; you love its screen; it has a very fast processor; you are a power user and you are glued to your device….but you are unhappy with the battery. You ask “Why can’t I get a battery with larger capacity?”, but no one seems...
So you decided to buy a new mobile smartphone. You researched the internet; you looked at the web reviews; you have decided on what OS you prefer, iOS, Android or even Windows; you looked at the quality of the built-in cameras and you know how many megapixels...
We are happy and flattered by Antony Leather’s report today in Forbes on Qnovo’s fast charging. A self-described passionate of gadgets, Antony understands many of the subtleties of the batteries and their challenges in mobile devices. The media is now paying a...
I was greatly entertained to read about a newly reported discovery from Nanyang Technology University claiming a new battery that can charge to 70% in a mere 2 minutes, yet last 20 years, or about 10,000 cycles. There were recent reports in the media for similar...
I covered in the prior post about the ill consequences of charging a lithium-ion battery using constant current, constant voltage (or simply CCCV). The damage incurred within the battery during charging with CCCV is attributed to a series of undesirable side reactions...
CCC…what? Yes, it is a mouthful and it stands for “constant current constant voltage.” It is presently the charging approach used for lithium ion batteries. As I indicated earlier, it was invented in the 19th century for charging lead-acid batteries, and somehow...
No, it is not “Batteries Made Simple,” nor “Better Make Sense,” though BMS do indeed try to accomplish both in a very indirect and implicit way. BMS stands for Battery Management Systems. These are electronic systems, both hardware and software...
Today’s post takes us on a brief journey inside a lithium-ion battery. What is its internal structure and how does it actually store electrical energy? Let’s first start with a capacitor…the kind of stuff you studied in high school physics. It has two plates separated by an...
Did you know that the first battery was invented in 1791 by Volta using alternating zinc and copper plates? Did you know that the first rechargeable lead-acid battery was invented in 1859? It remains to date used in automobiles worldwide and is one...
So you are happy with the large battery in your new iPhone 6 Plus. Finally, Apple listened and put a large, nearly 3,000 mAh, battery in your device. Finally, Apple followed the rest of its Android-based competitors who already had scaled their batteries to...
For those of you who are not familiar with ARPA-E, it is an acronym that stands for Advanced Research Projects Agency – Energy. It is an agency of the U.S. Department of Energy, and was formed in 2007 by the America COMPETES Act with the intent...
I love my electric vehicle, or EV, as we affectionately call our electric cars here in California. I love that it is quiet. I love its fast pickup from a stop. I love that it requires practically zero service: no oil change; no transmission service; no timing belts. Of course...
