OT: Do electric cars let you monitor INDIVIDUAL battery temperature?...

[John Doe]

I defined a common English word (sense), that Always Wrong uses every day.

Must suck to feel such hostility towards others. If it isn\'t me, it\'s
somebody else, as Always Wrong always does in this group for so many
years...

If you had enough brains to have read my post, I detailed where
idiots primarily in the US starting in the \'60s started incorrectly
calling a single cell a battery.

It got adopted by Webster and both the term \"cell\" and \"battery\" are
now considered correct, worldwide, even for units which are singular.

It is common for idiots like John Dope. Same type of idiot that
refers to a tissue as \"kleenex\".

Poorly raised word challenged AND discipline challenged (that follow
ups stupid shit you pull).

Doesn\'t matter how many batteries there are. The more batteries, the more
important for the driver to know what\'s going on.

A battery is a battery of cells. The cell is a component with two different electrodes at each end, and a battery of cells is built up out of an arbitrary number of individual cells connected in parallel and in series.

It\'s very helpful to know the temperature of the cell in the middle of the battery - it\'s mostly going to be the hottest cell in the assembly.
If there is variation between individual cells you may get hotspots elsewhere, and four more sensor arranged as tetrahedron around the centre can let you pick this up.

I suppose they do not keep track of individual battery temperature, but maybe
they should. I would want that. Too many batteries to keep track of? Then too
risky.

The temperature if an individual cell is determined both by the heat being generated in that cell and the heat being generated in adjacent cells.
The temperature of the central cell is determined by the thermal gradient from the central cell out to cells on the periphery of the battery, who have to dissipate the heat they generate, and the heat generated by all the cells in the layers below them.

Monitoring the temperature of individual cells would probably be an overkill, but monitoring the half-way points on the thermal gradients could well make sense.

Flyguy has already posted idiotic misconceptions about this sort of stuff. I\'ve suggested that you aren\'t quite a stupid as he is, but it\'s arguing precedence between a flea and louse.

From Merriam-Webster...
battery: a single cell that furnishes electric current
\"need to replace the flashlight\'s batteries\"

Typical John Doe - he chops the test down to the fragment that fits his idea. Including a bit more of the original text shows him up

https://www.merriam-webster.com/dictionary/battery

4a : a combination of apparatus for producing a single electrical effect a battery of generators
b : a group of two or more cells (see cell sense 5) connected together to furnish electric current also : a single cell that furnishes electric current need to replace the flashlight\'s batteries
c batteries plural : level of energy or enthusiasm needs a vacation to recharge her batteries

At least here in America... That\'s common, to call one battery in a group
of batteries a \"battery\". When we replace the batteries in a device, no
matter how many there are, we say we are replacing \"batteries\", not the
\"cells\".

It maybe be common, but - historically speaking - it is wrong.

At least here in America... If one wanted to monitor the temperature of
each battery in a flashlight battery compartment, saying \"I want to
monitor INDIVIDUAL battery temperatures\" is perfectly acceptable English.

Not to me it isn\'t. It would also be a moronic over-kill

I\'m not bashing the bashers for calling them \"cells\".

Language is for communication and NOBODY misunderstands what I\'m saying.

It\'s not difficult to work out that you have never got anything useful to say. You do communicate your idiocy remarkably reliably, though not as concisely as we would prefer.

They are called cells. A group of cells is called a battery.

It was always that way. Even a nine volt battery is a group of
small cells. Individual cells like C cell or D cell or AA or AAA
cell got called \"battery\" by idiots in the \'60s and beyond until
Webster finally \"adopted\" battery as meaning any DC power source.
Another place where America\'s folks got the dumbed down version and
now they are all that way.

But in this case... These are individual cells arrayed together to
form a battery. And individual cells can be and likey are
temperature monitored but likely would not \"let you monitor\" it. It
is internal. Part of the charge/discharge \"watchdog\" circuitry.

On the Chevy Volt you can monitor the voltage of every individual cell
with any OB2 app, don\'t know about individual cell temperature or
whether that\'s even relevant information for the ECU, maybe not.

Individual cell temperature is surely monitored internal to the battery
by the battery controller and if something\'s seriously amiss it\'ll flag
the ECU and report some cryptic battery-related fault code to the user
A Tesla has 3k to over 6k cells, depending on model. I doubt they have
thousands of temp sensors.

Analog Devices has been aggressively pursuing this market for at least the past ten years that I know of. The difference in capability between ten years ago and latest developments is as stark as night and day. And it looks like they\'ve been pretty successful at capturing the market. Just like every airbag system in the world used their accelerometer line, for a while anyway.

EVs are just one part of their business. They\'re out to capture every battery application out there. They see the stringent government safety regulations coming.

Bozo LIES about what Merriam-Webster says.

Merriam-Webster says \"a group of two or more cells\" then it continues
with...

ALSO: a single cell that furnishes electric current
\"need to replace the flashlight\'s BATTERIES\"

At least here in America, a \"battery compartment\" is full of BATTERIES
not CELLS.

https://care.hallmark.com/s/article/How-to-clean-a-battery-compartment-containing-corroded-alkaline-batteries

1. Put on disposable protective gloves
2. Open the BATTERY compartment
3. Carefully remove the damaged BATTERIES aand place each BATTERY in a
separate sealable plastic bag
....
8. Dry the contacts with a disposable towel or fresh cotton swab and place
new BATTERIES iinto the compartment

How? I posted a direct link to what Merriam-Webster said, then cut and pasted the relevant bit of text, just enough to make it clear that you had been text-chopping. You\'ve snipped it, which is lying by omission. I\'ve put it back.

https://www.merriam-webster.com/dictionary/battery

You don\'t buy the cells - you buy the battery which mostly turns out to be assembled out of cells by the manufacturer.

The fact that barely literate American manufacturers don\'t express themselves clearly isn\'t exactly relevant.

Don\'t forget where the word battery came from:

\"Historically the term \"battery\" referred to a cluster of cannon in action as a group, either in a temporary field position during a battle or at the siege of a fortress or a city.\"

No. Just much too stupid to get the point.

> Language is for communication and EVERYBODY knows what I\'m talking about..

All you ever talk about is how stupid you are. You clearly don\'t realise this, but this is the only message you can communicate.

The point about using \"cell\" in your message was that it would have let you be specific about the element whose temperature you were measuring.
If a battery is a collection of cells, it is lot easier to talk about measuring the temperature of a specific cell than it is to talk about measure the temperature of an individual \"battery\" inside an assembly of batteries (also called a battery). Communication is designed to make life easier for the reader, but that\'s a higher level communication than you are equipped to process.
