Overview:

Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

Comparing this specific heating per volume, the Tesla 4680 cell creates around 2x of the heat to be dissipated at a 1 C load (Figure 8). Thus, when designing a system with the same power requirements, the cooling needed for the Tesla 4680 cells must dissipate approximately 2x more heat per volume than that needed for the BYD cell at the same load. Therefore, the LFP electrode design is more favorable for designing a cooling strat-egy for fast charging.

Interesting that Tesla is the king of fast charging, despite the technology being objectively worse in a fast charging application.

Their charging network’s handshake speed is just so far ahead of everyone else, as is their reliability.

Conversely, their vehicles’ fast charging curves are comparatively dog shit.
