A tech news sub for communists
Thats cool and all but why do they compare charging an EV to refueling a tank? Who drives a tank?
I'm starting to suspect you're not in fact a genuine tankie!
I like fast charging but I like swappable batteries even more
BYD has various meanings:
For Chinese, it's biyadi
For Westerners, it's Build Your Dreams
For Western capitalist auto makers, it's Bringing Your Downfall
This could be good, but as a EV owner I am not convinced that I need a recharging speed that is this fast. I own a Chevy Bolt ( known for its sloooow charging speed) and even when we travel longer distances and need to charge stopping for 20 minutes would be great ( thats a bathroom break and snacks) so I applaud the technology but I think pushing the envelope down this far is not what most people would need.
Renters exist, and many of them don’t have the option to install charging infrastructure in their homes everywhere and every time they move. Their options today are:
Faster charging lets people get in and out of charging stations faster, which lets more people charge, which makes EVs a more practical option for people other than single family homeowners with garages
There is literally no downside to having faster charging.
That is true ! I was just thinking out loud about “ How Fast “ we should worry about/ invest in vs getting more fast ( 160kw+ ) charging stations for the general public to use.
I think fast charging negatively impact battery life because of the heat it produces. It would be nice to be able to choose the amperage we want for a specific charge, when we're not in a hurry.
Which is why i still think that the best solution at the moment is still battery swapping stations. That way you get the best of both worlds. Your vehicle is back at full charge within a couple of minutes (the only limitation is how fast the mechanical operations can be performed), and the batteries themselves can be charged as slowly as needed to preserve long term battery life.
i mean the engineers developing this must be taking that into account, we don't have to be worrying about this.
I would imagine they've considered batter degradation here. It could be that the approach they use doesn't cause significant damage to the battery.
They actually tell you it’s better to charge it with the slow charger most of the time. The fast charger does have a negative effect on battery life. I don’t know how significant it is though.
It'd be interesting to see what the difference is there. The ideal would be if you have a charger capable of rapid charging, and you can dial it down if you want to assuming there is a negative effect on the battery.
