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 :(
