BYD just launched the largest car carrier to charge up its global EV ambitions

3 months ago (electrek.co)

Living in Australia, I chose a BYD over a Tesla. After previously owning a Nissan Leaf, I can clearly see why BYD is leading the EV market.

Vertically integrating. Not as subtle as I'd have expected, but still sensible.

Their workers work 12 hrs a day and only get 2 days off per month. It's the worst kind of modern slavery. I don't think they can produce even qualified cars under such pressure.

The number of RORO ships is directly proportional to the volume of automobile exports. As of 2022, China had only 100 such ships, accounting for just 14% of the global fleet. However, considering that Chinese shipbuilding enterprises currently have orders for an additional 200 RORO ships, it is possible that in the future, China's share of the global roll-on/roll-off fleet could reach one-third.

GOOD Point by my wife. Could they double purpose these ships as ferries? Seems like the same basic concept.

  • It's not well advertised, but you can book voyages on many cargo ships. They just give you one of the crew cabins and pack some more food. Expect to be the only passenger.

    There are some issues though. It's slow (slower than an ocean liner since ships are more efficient at low speeds). And it's a cargo vessel, so the cargo sets the schedule. If there's an issue with the cargo that delays the ship by three weeks, you journey is delayed by three weeks. There also just isn't much happening. You have a room, a mess hall, a crew of maybe half a dozen to a dozen people to talk to, a ship to walk around on, and not much else.

    It's more of a "the journey is the destination" thing. Accordingly there are a couple youtube channels documenting such journeys

    • As an astronomy buff, I would do that just to observe the stars from the ocean.

      Do you know if they can turn off the bright lights at night? Even for just an hour, coordinated with the crew or captain? I might consider such a journey. I've never seen the southern hemisphere sky.

  • Probably not enough space for people. Often people aren't allowed to stay in their cars.

I'm just here to say electrek's continuous scroll both delights and annoys me by equal measures (because of my right click new tab habit)

This is a giant RoRo. Compared to the one I used to cross the St Lawrence River a few years back, you could pack hundreds of them inside this in a meta meta car carrier.

After the Ticktock ban and surge of Rednote installs, more people are seeing these cars here. And they look amazing for the price. The ban is backfiring spectacularly. And this is just one way.

Ten thousand EV batteries packed into a ship’s hull.

What could go wrong?

  • I actually assumed that was part of the impetus for creating their own ship – standard cargo ships probably aren't well-suited to the job and simultaneously are a bit concerned about transporting such cargo.

    • Specialized car carriers are fairly common. Maybe they added some changes to make this one especially well suited for EVs, like modified fire suppression systems. But it may well be a standard ro-ro ship with an LNG engine.

  • It would be cool to pull charge off the batteries to power the ship.

    • I estimate that all those batteries would get that ship at most 20% of the way across the Pacific.

    • The ship runs on LNG, which is probably cleaner than charging the cars in China and using that for energy, given China's grid mix.

    • It seems to already use some batteries, but not sure for what:

      “the new ship includes BYD box-type battery packs and shaft-belt generators for the first time”

  • Realistically, what is the concern for EV batteries? They already make up a pretty substantial amount of market chair in the US, and yet I don’t hear stories about EV’s being more dangerous or more prone to fires or anything. The only time you ever really see an EV burning is one that was in an accident, and guess what, gas cars also blow up when they’re in an accident sometimes

  • In terms of fire risk, ten thousand gasoline cars are worse. And they have to be fueled because the cars are driven in and out of the carrier.

    EV fires are harder to put out, but in every other way this isn't different from any other car carrier

This ship might not be for peacefully exporting electric cars. China is making unmistakable preparations to invade Taiwan in the near future and RORO carrier vessels have clear military applications in such a scenario.

Consider this analysis of the invasion barges they’re preparing: https://m.youtube.com/watch?v=Klkpk_hO4FQ

  • Why not both like Merchant Marines.

    Dual use sealift is just common sense. Too many years of stupid western analysis that PRC would waste $$$ to build dedicated TW amphib fleet, and point the absence of one as PRC not ready to invade TW. Reality is every $$$ PLAN spends on sealift is one not spent on weapons shooting back at US+co.

    PRC RO/ROs (and a lot of other commercial shipping) are indeed build to military standards for TW scenario. Used for shipping cars like they're suppose to during peacetime to let that capex work, and armor vehicles during war.

    Comparable RO/ROs have been actively involved in invasion TW training/exercises. PRC RO/RO numbers a couple years ago was enough to land 7 full PLA group armies (300k + equipment) on TW in about 10 days, or every US Army Brigade Combat team in 5 days. They'll probably have enough RO/RO sealift to cut that down to 2-3 days in a few more years.

    • China still has an amphib fleet, and there are reasons to use amphibs for at least the initial forced entry operation, but once you have a beachhead the dual use ROROs are a good way to sustain and reinforce the landing force without needing to capture or build a port facility.

      And it’s not like the amphibs are only useful for Taiwan; there are plenty of disputed islands in the South China Sea worth fighting over.

  • This boat could be easily sunk by drones or a guy with a big gun. Taiwan has plenty of both. Only way China sends this ship to Taiwan is if they already have a strong beach head and supply lines. At that point it’ll be tough for Taiwan either way.

    • > This boat could be easily sunk by drones or a guy with a big gun. Taiwan has plenty of both.

      And China has plenty of RORO ships.

      > Only way China sends this ship to Taiwan is if they already have a strong beach head and supply lines.

      Yes, this is what I was saying here: https://news.ycombinator.com/item?id=42746043

      These ships are the supply line. Sustaining a landing force after capturing a beachhead is an important problem and these ships are the solution.

      > At that point it’ll be tough for Taiwan either way.

      Yes but it will also be tough for China if their landing force can’t get reinforcements, food, fuel, and ammunition. A beachhead is just the beginning of a much harder fight to come through the cities and mountains of Taiwan.

  • Car shipping RORO vessels aren't LSTs... They can't beach and land tanks. Amphibian tanks can roll on and off amphibious assault ships, but this isn't it.

    • You probably wouldn’t use a ship like this in an initial landing, but once you’d secured a beachhead you could easily use it to deliver reinforcements and supplies. A major part of the value of a RORO ship is that you need little to no port infrastructure to unload it. Once you’ve secured a beachhead and built some minimal infrastructure on it you could land tanks and other armored vehicles, or you could also land trucks filled with fuel, ammunition, supplies, infantry, and so forth. This is, in practice, most of the work that LST’s did as well.

      And it’s very common to requisition merchant RORO ships for amphibious operations. The British did so during the Falklands War (https://en.m.wikipedia.org/wiki/SS_Atlantic_Conveyor).

  • That is a very good observation and a really interesting video.

    • Yeah, I watched the video the other day and when I saw the phrase “world’s largest car carrier” I instantly thought of the photo of all of the Chinese tanks loaded onto a RORO. And this ship is even bigger? Hmmmmm…

Why does the Heifei look like 1/3 of a cruise liner? What happened to the badonk tail end?

To be fair, it's pretty large. If you zoom in, you can see some people in a door near the middle of the image, and they're nearly microscopic.

So Internet apps are banned but data collection devices like electric vehicles are permitted. BYD of course has a privacy policy, but who knows what is actually collected. The same applies to other EV manufacturers.

I suppose one can only buy 30 year old second hand vehicles.
