BYD 5 minute EV charger

[Bergslagstroll]

Marketing is all about perception and consumers can be sceptical of new technology. So extremely fast charging from BYD and other car companies can be an important part in winning over sceptics. Even if most car owners can be fine with much slower charging times. Because of the opportunity to charge at home and also for example combining charging with meal breaks during long trips.

Wow, interesting- that really is breakthrough technology if real. I have an EV- a Chevy Bolt EUV. I love that little car- it’s great for driving kids to school, going to work every day, and going on the town or the suburbs on the weekends- about 95% of our needs. But I avoid it for road trips because of this “”range anxiety”. If you can have these 5 minute fill ups, that ahould eliminate the last big hurdle for even more widespread adoption of EVs.

I am trying to imagine hundreds of these 1 MW charging station in an area randomly
turning on and off one megawatt loads.

I'm trying to imagine the heat generated in the car batteries when the charger is shoving a megawatt of energy into it.

My main complaint about (most) battery powered equipment is that it uses proprietary (non-standard) batteries and chargers.

That and the replacement cost of those items makes the purchase difficult for the average car buyer.

A few years ago I bought some Echo brand 58v tools (21” push mower, 16” chainsaw, string trimmer and leaf blower) from Home Depot, but Echo recently discontinued those and now makes 56v versions of them which use different batteries and chargers.

Eventually that will be worked out. Batteries will become standardized, just like gasoline is today.

EU made the USB-C plug a mandatory thing because every portable device maker wanted their own proprietary plug. Too many were winding up in the landfills.

To standardize metal screws (sizes, threads, etc.), it took an act of Congress in WWII. It was considered a matter of national security.

Toro makes both 60v battery and gasoline powered versions of its 54 inch zero turn mowers with the MyRide suspension. The cost is about $8K for the battery powered version and about $4.8K for the gasoline powered version.

A major disadvantage of battery-operated lawn mowers is their limited run time and the need to recharge. This can be a significant issue for larger lawns or if the grass is thick, as the battery may run out before the job is complete. Additionally, the replacement cost for worn-out batteries can be substantial.

That may (eventually) become so for the EV chargers, but the batteries will likely remain proprietary. It has certainly not happened for most battery powered tools/equipment. See post #8.

From China so I'm highly skeptical. If real it must be some capacitor + battery combo. I'd stand behind a barrier in case it blows up.

The potential for arc flashes while moving one Megawatt, in a detachable system seems like a real risk.
A company I worked for in the early 80's had a diesel electric ship, that had 1 MW generators to drive the electric screws.
While I did not work on the system, I was told the SCR room was not safe with the ship under way because of arc flashes,
and that was with connections bolted together. The plug would need some real safety features.

Many companies are working on getting the distance to increase and to get the charging to be faster, they might try to get it standardized but I suspect that will require regulation from the government. Companies like to compete to have the best car and at the moment they don't want to share that technology.

Which government? There’s no (global) standard even for household outlets.

The U.S. uses a standard voltage of 120V at 60Hz, while Europe uses a standard voltage of 230-240V at 50Hz. This difference in voltage and plug type means that European appliances may not work directly with U.S. outlets, and vice versa.

There's a time to get goverment involved to set standards and there's a time not to. We should let designs compete with each other and only win on technical/functional merits. Only when competing designs are functional equivalent should the goverment get involved and arbitrarily choose one.

Pretty sure the discussion is about Vehicles and the person I was quoting was talking about standardizing the car batteries for EVs.

As for which government, I was being generic as each country will have to pass their own regulations. Though I am sure once they do there will be conversations from all governments as to how to deal with that.

Errrrr.... Internal combustion engine cars are full of proprietary parts, but you're OK with that, I presume?

EV batteries last a long time, and manufacturers already plan to be able to replace depleted batteries.

As to chargers? Again, companies have spent decades figuring out how to adopt and use standards.

Why would having EVs sold in one country differ from EVs sold in another country be an improvement? As I noted, even common plug-in household electrical appliances currently differ, thus “conversations” didn’t “deal with that”.

You are trying to merge 2 different subjects, confusing what I am saying. Stick with the car batteries. I am not saying governments will automatically make everything perfect, I am just saying that at some point you will probably see government regulations on which technology to use on the EV batteries. and at some point the world governments will have a conversation on how to deal with the difference in technologies.

I didn't say they would agree, just that they would have the conversation.

They (generally) use the same fuel(s). Exxon’s fuels are compatible with all brands of IC vehicles.

lol... EVs also use the same fuel. Oddly enough, they don't all use the same gas tanks, why aren't you worried about that?

Meanwhile: China has around 100 EV manufacturers, and already uses the GB/T standard.

The US is already working on a standard. In the interim, you can just use an adapter.

This is not a serious issue.

The charging stations will have battery storage. There many other charging stations are also using batteries.

BYD's 1st 1,000-kW ultrafast charging stations to be ready for use in early Apr

BYD is pushing ahead with the construction of 4,000 1,000-kW flash charging stations, with the first batch of about 500 ready for use when the Han L and Tang L hit the market in early April.

This has already been comprehensively solved at 250-350KW as millions of people around the world can attest to every day, and as you know arc flash mitigation is not that much harder at 1MW, so this is a non-issue. Your 1980s crappy diesel ship that you didn't even work on has little in common with today's closed loop safety control systems for high amp power flow.

In China where these are being deployed, the nation has done a pretty good job from a regulatory perspective of developing and enforcing compliance with their GB/T standards which at least to my eye are currently world-leading in terms of safety, interoperability and capability (aside from the NACs connector pioneered by Tesla which is definitely superior). This shouldn't be too much of a problem in the mid and long term.
