BYD often states that its e6 all-electric car, offered mostly to fleets, has up to 186 miles (300 km) of range using over 60 kWh of energy.
Real-world range however is typically much lower (~140 miles), but BYD notes that there is a plan to increase the e6's range by one third to up to 400 km (250 miles).
According to ChinaAutoWeb, China’s Ministry of Industry and Information Technology released a list of upcoming EVs qualified for sales tax exemption. The list includes a new version of the 2016 e6 (BYD 7006BEVH).
The battery pack will be increased to 82 kWh (weight of 700 kg) and range will move to 400 km. Curb weight of the car will be 2,420 kg / 5,335 lbs.
e6 always was a heavy vehicle, but now despite more battery capacity, its weight will raise only slightly. The reason is significantly higher energy density - 150 Wh/kg instead of 117 Wh/kg (we believe at the cell level).
"Compared with the current, 2014/2015 model, the 2016 e6 will be even heavier (2420 kg vs 2380 kg in curb weight) and can cover a longer distance on one charge (400 km vs. 300 km). More importantly, it gets larger, better battery. The battery pack not only is heavier (700 kg vs. 600 kg) but has increased energy density of about 117 Wh per kilogram; that is, it stores 82 kWh of electricity, compared with the 60 kWh on the old one (although BYD claims that its new LFP battery has an energy density of about 150 Wh per kilogram)."
Sounds great, and if e6 gest new batteries, then all the other cars and buses from BYD should soon too.
