Advancements in EV Charging

Last March:

Chinese automaker BYD has just set a new benchmark for electric vehicles (EVs), unveiling a charging system that could drastically reduce charging times and reshape the industry.

BYD’s new battery and charging platform can deliver 470 kilometers (292 miles) of range in just five minutes, according to Chairman and founder Wang Chuanfu.

As BYD plans to roll out over 4,000 charging stations to support this system, the move could further accelerate its rapid growth in China, where the company already holds nearly 15% market share.

While revealing a set of new products, CATL said that one of its latest battery can add 520 km (323 miles) of driving range to an EV after just five minutes of charging time.

This BYD or CATL new charging system will give the Tesla a run for its money.

First off there are 4 versions of the Tesla super charger.

The original V1 Superchargers provided a charging speed of 100 kW, but this was improved to 120 kW with the introduction of V2.

In 2019, V3 was launched, boasting more than twice the charging speed of its predecessor at 250 kW.

V4 350 kW 250 miles in 15 Min 3 meter Liquid-cooled
V3 324 kW 180 miles in 15 Min 1.5 meters Liquid-cooled
V2 150 kW 170 miles in 30 Min 2.7 meters Air-cooled
V1 120 kW 170 miles in 30 Min 2.4 meters Air-cooled

One can see a big difference in charging speeds. Have all the Tesla super chargers been updated? I could not find an answer. But my search skills may be lacking.

And an EV charging also depends on its architecture. Is it a 400 volt or 800 volt or 900 volt system?

And there is question on how fast an EV battery can be charged.

But there is a new breakthrough in battery technology announced today.

This advancement was made possible by the development of a new “cohesion-inhibiting new liquid electrolyte.”

Ajoint research team from KAIST and LG Energy Solution has announced a major breakthrough in electric vehicle (EV) battery technology. Their new research addresses the long-standing dendrite problem in lithium-metal batteries.

The researchers have developed a new lithium-metal battery technology capable of powering an electric vehicle for 800 km (497 miles) on a single charge and recharging in just 12 minutes

This technology is important for those making large distance trips in their EVs. For those that use their EVs for <100 mile trips not so much. They can charge over night with their level 2 chargers.

I know the Henrietta, TX are still V2. A few others here in Texas are as well. No idea how common.

Battery chemistry marches on, but the chemistry is only half the story – the ‘easy’ half. The other half is getting all that electricity in within a short period of time. A pod of chargers by the highway for these batteries would require the output of a small hydro dam, say 3.5 MW. (And the liquid-cooled charging cable will look like a giant python.)

My question, does this rapid charging shorten the battery life span?

Over 200 charging stations can be found at Pilot and Flying J travel centers located alongside interstate travel corridors.

The state of California has far more public EV charging ports than gas station fuel nozzles. There are approximately 120,000 gas pump nozzles, and 178,549 EV charging ports. There are an estimated 700,000 home EV chargers in California as well. The Golden State has about 39 million people. That is, the US state with the most people also has the most public EV chargers and the most electric vehicles. It also has the most home EV chargers. It’s worth noting there will be even more public and home EV chargers installed in California

No, not that I’ve seen. What is common(ish) is that they would have a location with 4 V2 chargers and they add 4 V3 (or now V4) and leave the V2 units in place. Upgrading probably not worth it and hauling away older ones not worth it. This is for relatively remote locations

XCharge North America (NA) and Ascentium Capital have launched a new leasing program to help small-business owners host DC fast chargers without having to front huge amounts of cash or rely on government incentives.

This should help the spread of fast chargers.

If you include Tesla chargers, they already are spreading quickly. Though, I would have to buy an adapter for my vehicle (ID.4). Which I may do. Tesla chargers are by far the most numerous at this time, and would be invaluable on road trips.

I do agree that this should aid the spread of non-Tesla chargers. Eventually, some group likely will catch up to Tesla in terms of extent of network. Especially with initiatives like this.

240v charging unit for apartment building and I assume for private homes for $450.
