Tesla is giving Model 3 Standard Range Plus reservation holders the opportun
ity to get their vehicles sooner. For early delivery, Tesla owners can opt t
o receive a Model 3 SR+ equipped with a lithium-iron-phosphate (LFP) battery
 pack instead.

As of this writing, January is the estimated delivery date of the Tesla Mode
l 3 SR+ in North America. However, base Tesla Model 3 reservation holders co
uld receive their vehicle as early as September if they opt to take delivery
 of a Model 3 SR+ with a battery pack similar to those produced in Gigafacto
ry Shanghai.

The one difference between the base Model 3 made in Tesla’s Fremont Factory
 and Tesla China’s Model 3 would be their battery packs. Fremont’s Model 3
 SR+ is equipped with Tesla’s nickel-based battery cells, while Tesla China
’s Model 3 uses an LFP pack

The battery packs have slightly different range estimates, which reservation
 holders may want to consider before taking Tesla up on its offer. The US-ma
de Model 3 SR+ has an EPA-estimated range of 263 miles per charge, while the
 MIC Model 3 with an LFP battery has an estimated range of 253 miles per cha
rge.

Elon Musk elaborated on Tesla’s decision to start offering base Model 3s eq
uipped with LFP batteries.

“Our intent with this pack is that product experience is roughly equivalent
 between nickel & iron,” he said. “I’d personally slightly opt for iron p
ack, as it wants to be charged to 100% whereas nickel prefers ~90%,” Musk w
rote.

The slight charging differences Musk mentioned between the packs may make up
 for the differing range estimates between the Model 3’s nickel-based batte
ry packs and those using iron-based cells.

There is a 10-mile range difference between the two battery packs, but the f
act that the LFP cells are best charged to 100% means that owners could freq
uently get their vehicles’ maximum range. In comparison, Tesla notes that v
ehicles with nickel-based batteries are best charged to about 80%.

During the last earnings call, Musk also suggested a preference for iron-bas
ed lithium-ion cells over those with a nickel base.

“I think probably there is a long-term shift more in the direction of iron-
based lithium-ion cells rather over nickel,” Musk noted.

“I think probably we’ll see a shift — my guess is probably to two-thirds
iron, one-third nickel, or something on that order. And this is actually goo
d because there’s plenty of iron in the world. There’s an insane amount of
 iron. But nickel, there’s much less nickel, and there’s way less cobalt,”
 he said.

As more automakers transition to manufacturing electric vehicles, the demand
 for raw materials to make battery cells to power EVs has increased. As such
, EV makers want to secure their raw material supply chain in advance. Tesla
’s shift from nickel-based to iron-based cells, which use zero cobalt, coul
d help it avoid supply issues in the future.

心得

美國Midel3 SR+車主選擇磷酸鐵鋰電池可以提早交付

馬神說他自己偏好鐵基電池
因為可以常常充到100%
也就是總是可以享受100%續航

相比鎳基適合90% 有些研究建議80%

並且說
將來電池會往鐵基發展
而非鎳基
特斯拉會有2/3使用鐵基電池(磷酸鐵鋰)
這是包含儲電設備的用量

在今年年初
福特表示 將使用LFP電池在商用車上
福斯表示 將在入門級別的乘用車使用LFP電池

個人一直比較推磷酸鐵鋰電池
是看中它在安全性的表現
先不提自燃
在一些中等的事故裡
人暈了或是卡住沒辦法馬上脫困是常見的
人還沒死這時候被燒死真的很不應該
