NEWS: BYD today ‌unveiled its second-generation Blade Battery with "Flash Charging 2.0"

新闻：比亚迪今日发布第二代刀片电池，搭载“闪充2.0”技术

• LFP
• Peak charging speed: 1,500kW
• 20% ​to 97% charge in under 12 minutes, even at -20°C (-4°F)
• Charges 10% to 70% in 5 mins
• 5% higher energy density
• BYD has increased the guaranteed capacity retention rate by 2.5% and promised a lifetime warranty on the battery cells
• Delivers a driving ​range of up to 1,006 km (621 miles) on the (optimistic) CLTC cycle, an improvement from the ~600 km (373 miles) range in the first-generation Blade Battery. The new battery would likely mean a 450 mile range if tested on the EPA cycle.
• Ten BYD models will be the first to feature the battery
• The Yangwang U7, equipped with a 150-kWh battery pack, "achieves a pure electric range of 1,006 km, while the fully electric Denza Z9GT have a range of up to 1,036 km" on CLTC cycle.

BYD also aims to expand its "Flash Charging" network to ​20,000 stations by the end of 2026, including 2,000 on highways. The company had built more than 4,000 stations as of March 5. However, keep in mind that in the past BYD has been slow to roll out promised ultra fast charging infrastructure expansion.

- 采用磷酸铁锂（LFP）技术

- 峰值充电功率：1500千瓦

- 即使在-20℃低温环境下，电量从20%充至97%仅需不到12分钟

- 5分钟可将电量从10%充至70%

- 能量密度提升5%

- 比亚迪将电池保底容量保持率提高2.5%，并承诺电芯终身质保

- CLTC工况下纯电续航最高可达1006公里，较第一代刀片电池约600公里的续航显著提升；若按EPA工况测试，续航预计约450英里

- 首批将有10款比亚迪车型搭载该电池

- 仰望U7搭载150千瓦时电池组，CLTC纯电续航达1006公里；纯电版腾势Z9GT CLTC续航最高可达1036公里

比亚迪还计划在2026年底前将“闪充”场站扩充至2万个，其中高速场站2000个。截至3月5日，已建成超4000个场站。不过需注意，比亚迪过往在兑现超充设施扩建承诺方面进度偏慢。

以下是各国网友的评论：

Wow, impressive. Gotta be quick with those bathroom breaks.

哇塞，太厉害了。这下上厕所都得抓紧时间了。

Chickadee Chai
Is this really a pain point? Aside from one road trip where I was late, I can't think of a situation where I need this.

快充真的是痛点吗？除了有一次自驾游迟到，我真想不出什么时候需要这么快的充电。

Matthew Santoro
I mean there's no real downside

说实话，这东西真没什么缺点。

Alexander Brueck
It’s better…so why would you prefer something worse?

充电速度更快肯定好啊，你为什么会想要慢的？

Chickadee Chai
Because it costs money that could have been used to lower prices or invest in something more useful.

因为这需要成本。这笔钱本来可以用来降价，或者投在更实用的地方。

Chickadee Chai
Steve Jobs never added a keyboard, but here we are.

乔布斯当年也没给手机加键盘，结果现在还不是都有了。

David Read
It is. I don't road trip often, but do day trips to my kids homes, easily done on a tank of gas, requires a big charge stop and a quicker one to get me the rest of the way home. Turns a 5 hour trip to 6 hours. We all know highway range isn't good, esp in winter.

确实是痛点。我不常长途，但会当天往返孩子家。燃油车一箱油就够，电车却要充两次电。5小时路程变成6小时。大家都知道，电动车高速续航本来就差，冬天更糟。

Chickadee Chai
3-5% of users see this as a problem. Worth offering an extended battery or something vs building out an extensive and expensive infrastructure.

只有3%–5%的人觉得这是问题。与其砸钱建超贵的庞大充电站，不如提供长续航电池之类的方案。

Kevin Nearhoof
Range is everything the only reason I sold my model Y was range I couldn’t go from Miami to Orlando without charging.

续航就是一切。我卖掉Model Y就是因为续航不行，从迈阿密到奥兰多都必须中途充电。

Chickadee Chai
I rarely use more than 50 miles a day. extender batteries are the way to go - lower the base range to 200 miles, then charge for additional batteries.

我一天最多开50英里。应该搞电池升级方案：基础续航200英里，想要更长续航再加钱买电池。

Tyler Branstetter
As a Tesla owner, I likely will never buy another new Tesla.
1). I am very disappointed in charging speed
2). I think their approach on FSD subscriptions is insane and I won’t pay a high monthly fee to use the things that my car can already do.

作为特斯拉车主，我大概率不会再买新车了。

1. 充电速度让我非常失望

2. 我觉得FSD订阅制很离谱，车本来就有的功能，我不想每月花高价用。

AM
People live all over the world. Some drive in cold weather which eats up 50% of their battery on any reasonable long drive so for them it would be a big relieve. This is a major reason, but regardless technology should always evolve.

大家住在世界各地。有些人在寒冷地区开车，跑长途续航直接砍半。快充对他们来说是大救星。这是重要原因，而且技术本来就该不断进步。

Cr4sh
I can see it being borderline essential for anyone using an EV all day every day for work, think taxs, medical couriers, sales reps.

对于每天整天开电车干活的人来说，快充几乎是必需的，比如出租车、医疗配送、销售外勤。

sunflower22
Once you have experience of an electric car, it really isn’t a pain point. But many many ICE drivers hesitate to buy one because of this. Of course there’s the segment of ”petrol heads” who would never consider EV, but I reckon that’s a small minority.

开过电车就知道，充电其实不算痛点。但很多燃油车车主就是因为这个不敢买。当然也有油车发烧友打死不买电车，但我觉得这只是少数人。

Max Leverage
This is a pain point that needed to be fixed. Same with the better range.

这就是个必须解决的痛点，续航提升也一样。

Sixers in 5
Faster is always better - not a pain point for most but nobody would want slower charging.

越快越好。对大多数人不算痛点，但没人愿意充电更慢。

David Havasi
The question must be asked- why isn’t Tesla doing this?

必须问一句：为什么特斯拉不做这个？

The Duke of Kewpie
Why isn’t Tesla doing this?
Because I think the marginal benefit above current supercharger capabilities is, well, marginal.

为什么特斯拉不做？因为我觉得，比现在超充再快，提升其实很有限。

Matt Linn
Where is the “Tesla is ten years ahead of the competition” gang now?

当年喊“特斯拉领先业界十年”的那群人，现在去哪了？

Lincoln
If any of these quick batteries charging times ever up being true and they are affordable and scalable it could introduce an issue for Tesla right?

如果这些快充电池真能实现，还便宜、能量产，那特斯拉确实会有麻烦，对吧？

ignitei
BYD is moving fast.
Second-gen Blade Battery: 1,500 kW peak, 20% to 97% in under 12 minutes — even at -20°C — plus lifetime cell warranty and big range jumps.
Respect the progress. Competition like this raises the bar for everyone.
Tesla’s deeper advantage stays the same: real-world EPA testing, the world’s most reliable charging network, and unsupervised FSD that turns charging time into productive (or slee) time.
The full stack wins long-term.

比亚迪进步很快。第二代刀片电池：峰值1500kW，-20℃也能12分钟内从20%充到97%，还有电芯终身质保，续航大幅提升。确实厉害。这样的竞争会拉高整个行业的标准。

特斯拉的核心优势还在：真实EPA续航、全球最稳的充电网络、无接管FSD——充电时间可以用来工作或睡觉。长期来看，全栈技术才是赢家。

Mistak
These always seem so neat but who is building a 1.5 MW charging network? It's a challenge even for Tesla. Are charging stations that can handle that load common in China?

这些参数看着很牛，但谁来建1.5MW的充电站？就算对特斯拉也是挑战。中国能承受这个负荷的充电站很多吗？

The Cybertruck Guy
Why can't America do this

为什么美国做不到这个？

Mark Prati
Good charging speed, but the 1006 km range sounds impressive but in reality it’s only ~ 460miles using EPA range testing. About 30 miles more than a Model S.

充电速度是不错。1006公里续航看着吓人，但按EPA实测也就约460英里，只比Model S多30英里左右。

Chas
No competition, and Tesla is to focused on costs vs. charging performance. Tesla thinks 5%to80% 40min is acceptable! It’s not acceptable for road trips.

完全没竞争力。特斯拉太在乎成本，忽略充电性能。特斯拉觉得5%充到80%要40分钟可以接受！跑长途这根本没法接受。

TED
America and Tesla could do this.
But they won’t.
Because it’s stupid.
First, it’s unnecessary. Charging speeds can and will improve but this is excessive and dangerous. Second, the cost all around is prohibitive. Third, it can’t be good for battery durability.

美国和特斯拉能做。但他们不会做。

第一，没必要。充电速度会提升，但这么快过头了，还危险。

第二，整体成本高到离谱。

第三，对电池寿命肯定不好。

loudog
How long will it last in the real world is one question, AND: can we even supply enough power to our chargers to widely deploy this? It's going to take a while

实际能用多久是个问题。还有，电网能不能撑得起大规模部署这种快充？还早得很。

dannydigital
too many rednecks and people who struggle with math

太多人不懂逻辑，也算不清账。

greatauto
If true, the charge‑rate vs cycle‑life tradeoff is the real test. 1.5MW peak is wild, but pack‑level thermal management at −20°C + durability will decide adoption. Curious if BYD published cycle‑life + pack‑level specs.

如果是真的，充电速度和循环寿命的平衡才是关键。1.5MW峰值很夸张，但-20℃下的电池热管理+耐用性才决定能不能普及。好奇比亚迪有没有公布循环寿命和电池包参数。

BRCooper
Tesla seems to have given up on increasing charge rates of their batteries.

特斯拉好像已经放弃提升电池充电速度了。

Ninus
No need honestly
If anything, the superchargers need to be slower. I barely have time to grab a sandwich before I have to go back to the car.

说实话，没必要。我反而觉得超充应该再慢一点。我刚买个三明治，就得回去挪车了。

BRCooper
The vast majority of drivers are never going to buy an EV until they charge in less than 10 minutes.
You can explain to people until you are blue in the face that most charging takes place at home, Supercharger stops aren't that long and they're only for road trips, no oil changes, etc., and it only sounds like pure cope to ICE drivers.
"Cool bro. I fill my truck up in 5 minutes."
I drive a Model Y. I understand the realities and tradeoffs of charging. I can't convince anyone else to buy one and charging times are nearly 100% of the reason why.

绝大多数车主，只有在电车10分钟内能充满时才会买。你就算说破嘴，说平时都在家充、超充也不算太久、只是长途用、还不用换机油，油车车主只会觉得你在找借口。

“厉害哦兄弟，我皮卡5分钟加满油。”我自己开Model Y，我懂充电的现实和取舍。但我说服不了任何人买电车，几乎100%都是因为充电时间。

Distress Signal
We don't know the long term use case of these batteries yet. Claims can be made all over the place.

这种电池的长期表现我们还不知道。宣传谁都会吹。

Victoria Zeev
1,500kW charging and 1,000 km range? Sounds impressive on paper, but CLTC numbers and lab conditions aren’t the real world. Let’s see independent tests before calling it a breakthrough.

1500kW充电、1000公里续航？纸上看着很牛，但CLTC工况和实验室数据不等于现实。等第三方实测出来，再说是突破也不迟。
