主题：【原创】比亚迪电动车的情况汇报 -- 1cat

Nice indeed, but I am kind of skeptical, 200miles requires 40 to 50Kwhrs of battery ~ 400/500Kg, GM has hard time to get 18KWhrs battery and the price is already a big issue, so how come these guys can claim such product??

The Volt uses 100 Wh/kg batteries and only allows 50% depth of discharge, so has total 16 kWh of which 8 kWh is used in a pack weighing 160 kg.

The BYD car probably uses deeper cycling, say 80%. At 100 Wh/kg it would require 37 kWh to achieve 186 mile range, or 47 kWh to keep to 80% cycling limits.
