Welcome back to Evie News Daily coming up today. How to Hack a Rivian battery, Tesla's self-driving for Europe and China, and Volvo's upgrade for 2.5 million drivers.

Plus, stay tuned because later in the show, I'll tell you why Tesla's legal team has forced one charging company into a U-turn on their products.

Well, good morning, good afternoon, or good evening.

Wherever you're listening around the world.

but the Gen 2 vehicles, which are now rolling off the line, have the option of a battery pack

called Large Plus. Now, the Large Plus battery pack has been observed to charge and charge

and charge beyond 100%.

Not just the trickle charge that happens at the top of all lithium-iron batteries where it really slows down, but it raises questions about the nature of this battery.

What exactly is the large plus pack and how does it differ from standard large and the max pack?

Well, the large plus pack is actually a software-capped max pack. Now, we've seen Tesla do this over the years, many times, especially in the early days of the Model S in the company as well. They're just for ease of production and supply chain and putting the cars together, you could have a bigger battery than you wanted,

and they would software lock it. You would pay less money. It's happened with other models over

the years as well, but it was quite common on Model S early days Tesla, and you could then

pay to have it unlocked in some cases. And also, the good thing is, because you were physically

carrying around a bigger battery, what was 100% on your dashboard, which is just software and an algorithm, wasn't really 100%.

Because, I mean, no lithium ion battery is really 100%, even when your car says it is.

All buffers are different.

But it meant that it was better for battery health if you did charge it to what says it was 100%.

There was good options, good reasons for doing this.
