Bolt是GM所生產的純電動車，續航力官方宣稱為238 miles(約380公里)
售價低於4萬美元，採用的電池組為60kWh+
GM最近公布了這個電池組的售價(非成本)為 15,734.29 美元
平均每一kWh售價是262美元
假設毛利率為25%，則其成本可能為196.5美元 /kWh
GM也有透露他們向LG購買電池的成本，為145美元 /kWh
比較一下
今年2月份，Tesla透過一則影片說明他們的電池成本已經低於125美元 /kWh
而電池組成本也低於190美元 /kWh
Chevrolet發言人也特別提到
他們在銷售Volt的七年當中，在保固期內沒有因為電池容量降低而更換過電池組
意思是要人不用擔心會需要換電池

GM lists the price of the Chevy Bolt EV's battery pack at $15,734.29 - $262/kWh
The cost of battery packs is still believed to be the main barrier in
bringing down the overall price of electric vehicles.
GM managed to bring to market the first electric car with a reasonable
price (<$40,000) and a large battery pack (60 kWh+), but it’s not making
a profit on the vehicle.
Again, the battery pack was believed to be the main reason and now we get
one more indication that it is the case based on the newly disclosed list
price of $15,734.29.
Chevrolet spokesperson Fred Ligouri confirmed the information last week
(via Green Car Reports):
“The current list price of a Bolt EV HV battery pack is $15,734.29 and
the part number is 24285978.”
To be clear, that’s the list price of the battery pack, not the actual
cost. It’s the price a Bolt EV owner would have to pay, at the
discretion of the dealerships of course, if they had to replace the pack
outside of the warranty for some reason.
Speaking of the warranty, Ligouri continued:
“The Bolt EV battery is covered by the electric-car propulsion warranty
(see specifics below) and Bolt EV customers shouldn’t expect to pay
parts costs for warrantied repairs.
In [almost seven] years of Volt sales we have yet to replace a single
battery pack under warranty for general capacity degradation, and many
owners are still reporting they enjoy the same range capability they had
when they purchased the car.
Whole battery-pack replacement is also largely mitigated by the design,
manufacturing technique, dealer diagnostic, and repair tools included to
support the manufacture, sale, and service needs of the Bolt EV, meaning
individual modules can be replaced should it be required.
In addition to the 3-year/36,000-mile Bumper-to-Bumper Coverage,
Chevrolet warrants certain components for each Bolt EV for 8 years or
100,000 miles (160, 000 kilometers), whichever comes first, from the
original in-service date of the vehicle … for repairs to the specific
electric propulsion components of the vehicle.”
While it’s not a perfect indicator of the actual cost of the battery
pack, which is made by LG Chem, it’s the best we have so far.
GM had already disclosed that it was paying LG $145 per kWh for the
battery cells of the Bolt EV. Assuming a 25% gross margin on the $262 per
kWh list price for the pack, it would come down to something like a cost
of $196.50 per kWh with a split of $145/kWh for the cells and $51.50/KWh
at the pack level costs, which would actually make sense.
I wouldn’t expect the OEM markup on the pack to be any more significant
than that considering GM confirmed losing money on the vehicle, but your
guess is as good as mine at this point.
For comparison, Tesla was talking about an overall battery pack cost of
less than $190 per kWh last year. The company claimed that Gigafactory
would reduce that price by roughly 30% for the Model 3 when it plans to
hit volume production of 35 GWh in 2018.
Most automakers and battery manufacturers are keeping the cost and specs
of their battery cells and packs close to their chests and therefore, it’
s interesting to see some of that information become public.
