The correct answer is two. One is the large one that runs the motors, the other is a small 12 volt unit that runs the ancillary systems (vehicle electronics, mainly), and is charged by the large battery.
The original definition of "battery" was a combination of two or more cells each of which individually store or produce electricity, most often by chemical means. The voltage produced by a single cell is often too small to be useful, so they are series connected to increase the available voltage. They are also parallel connected to increase the current capacity.
A modern example is the 12 volt lead-acid car battery which consists of six 2-volt cells.
The definition has been broadened so that single cells (like the common D-cell) are generally called batteries.
The EV main battery consists of thousands of individual cells, the exact number depends on the make and model of the vehicle.
That's not even close to being true.
Oil and gas are green energy from plants that lived millions of years ago, Ancient sunlight made these Jurassic era plants grow. Other eras too. That have been stored underground. Compressed and refined over millions of years, into product that we can refine and use. Or that needs a little cleaning up like natural gas.
The grid is what it is all about.
Think of the billions to be skimmed off a trillion dollar plus upgrade...
We should adopt the vernacular of the left and call these batteries BLOOD LITHIUM
I am confused by your response.
I pinged this article because I wanted to my 12 year old grandson to read it. I believe he will find it interesting.
I just have one issue with nuclear power—all nuclear waste should be dumped in downtown Washington DC.
It is about time we started treating them like they treat us.
Ha ha!
(But actually the risk from nuclear waste is way exaggerated. It can easily be handled.)
Sorry, I’ll have Admin Mod remove the post.
Yes, good explanation for those not aware of the specifics. My daughter has owned a hybrid for 15 years. Some years ago she sat in the car with stereo and A/C on for a long time, then she couldn't start the car. Puzzled because she knew the hybrid had lots of battery power. Road service showed her that there was a small 12-volt battery that needed a jump-start. When the car is running, the large battery unit re-charges the smaller starter battery that runs the ancillary systems. The car was too dumb to recharge it while parked.
I have an EV that will automatically recharge the smaller 12-volt battery when it detects low-voltage, from the larger battery, and notifys the driver of the parked vehicle. I can use the ancillary systems for days if I wanted without depleting power.
