Battery system

For more details from the manufacturer, see their paper The Tesla Roadster Battery System

* Cell type: lithium ion, 18650 form-factor (18mm diameter by 65mm length). Most laptop computer batteries already use this type of lithium-ion cell.[16]
* Cell count: 6,831[17]
* Full-charge time: 3½ hours.[8]
* Estimated life: over 100,000 miles (160,000 km). [8]
* Electric energy: about 53 kW·h
* Total mass: between 900 and 1000 lb (400-450 kg)
* The pack is designed to prevent catastrophic cell failures from propagating to adjacent cells, even when the cooling system is off.
* Tesla Motors plans to sell the battery system to TH!NK and possibly others through its Tesla Energy Group division.[18][19]


53kWh = 2200 Ah * 24V
2200Ah / 4.2 Ah = 523 модуля
Каждый весит 2кг.
Т.е. для шЫкарной машины Tesla Roadster потребуется батарея весом с тонну.
Для более скромных машинок - поменьше.
Надо Профи дать на проверку расчеты :) Я уже весь школьный курс физики забыл :(
