Tesla Motors наносит сокрушительный удар по всем суперкарам мира

Я не постесняюсь спросить - а "батареи емкостью 250 кВ/ч" это сколько в Кулонах, ну или Ампер/часах? Может там у него генератор, тогда понятно почему мощность! Но емкость батарей в кВт.ч.?!?

Да и вообще, экономичность аккумуляторного электро-транспорта, вопрос довольно спорный. Если не сказать мифологический.
В ДВС, практически нет потерь на инфраструктуру передачи энергии. По крайней мере в сравнении с электросетями.

А теперь прикинем 1 л.с. = 0,735 кВт. Т.е. при замене мощности ДВС ну пусть в 110кВт (150 л.с.). Получается чтобы поменять 282 миллиона индивидуальных (!) автомобилей с ДВС на электроавтомобили, США нужно нарастить производство эл. энергии на 32 гВт, минимум. По статистике, при производстве 1 кВт.ч ТЭС сжигает приблизительно 1.4 кг. топлива (уголь - больше, газ меньше).

Отсюда вопрос, а сколько тратит топлива ДВС на производство того же количества энергии?

Вот приблизительно так все и получается, даже на уровне школьной физики, что для массового электроавтомобиля аккумуляторная система питания - фикция... Возможно в каком-то Монако и будет актуальна, но уже что-то типа Нидерландов - овчинка выделки не стоит, ни по экономике, ни по экологии...

SOLID-STATE BATTERY BREAKTHROUGH: FISKER INC.’S SCIENTISTS FILE PATENTS ON SUPERIOR
ENERGY DENSITY TECH, SHATTERING CONVENTIONAL THOUGHT ON EV RANGE AND CHARGE TIMES
• Fisker’s scientists, including the co-founder of global battery tech pioneer Sakti3, filed patents this week on flexible, superior energy density solid-state batteries.
• Breakthrough technology will enable dramatically longer ranges of more than 500 miles on a single charge and charging times as low as one minute – faster than filling up a gas tank.
• Automotive applications anticipated to be production grade ready from 2023 onwards.
• Fisker’s solid-state batteries will feature three-dimensional electrodes with 2.5 times the energy density of lithium-ion batteries.
REVOLUTIONARY SCIENCE. MULTIPLE INDUSTRY FIRSTS.
• Current limitations in solid-state technology include low electrode current density, limited temperature ranges, limited materials availability, high costs and non-scalable manufacturing processes. Early results show that Fisker’s solid-state technology enables the construction of bulk three-dimensional solid-state electrodes with 25 times more surface area than flat thin-film solid-state electrodes and extremely high electronic and ionic conductivities – enabling fast charging and cold temperature operation. As a result, Fisker’s battery delivers 2.5 times the energy density of typical lithium-ion batteries – with the potential of costing one third of the 2020 projected price of those batteries due to advances in materials and manufacturing.
• Several failure modes affect solid-state batteries, including low power and low rate capability due to high contact resistance and low ionic mobility in the layered electrode structures. Delamination issues due to volume changes and residual stresses during charge/discharge processes; dendrite penetration and stability vs. metallic lithium electrodes; and low ionic diffusion, particularly in low temperature climate due to solid-state material limitations, are also roadblocks. With the newly announced technology, Fisker’s scientists are addressing these technical bottlenecks. • Fisker anticipates the technology may be ready for automotive applications post 2023. Such long lead times are due to the lack of supply chains with particular raw materials and appropriate manufacturing tools, as well as established quality procedures for materials repeatability. Once the technology is fully validated, the battery will deliver a vehicle range of more than 500 miles
on a single charge, and charging times as low as one minute – allowing technology to bypass the internal combustion engine and push the automobile into mass electrification. Fisker is in active discussions with various industrial groups around potential non-automotive partnerships – with the possibility of battery applications that may be commercialized much earlier than 2023.



Figure: Fisker solid-state technology is capable of constructing bulk three-dimensional solid-state electrodes with 25 times more surface area than flat thin-film solid state electrodes and extremely high electronic and ionic conductivities – enabling fast
charging and cold temperature operation.

• Fisker’s flexible solid-state electrode construction will enable batteries with versatile voltage and form factors. They may be wound in cylindrical cells with higher voltage output, allowing usage of current tooling and machinery for battery packs – in addition to lesser cell-to-cell connections, thermal management and safety requirements. This further reduces battery system costs.
