See Energy Density Of Batteries From New Energy Vehicles

- Jan 09, 2017 -

GM's Bolt pure electric vehicle battery pack with a specific energy of ~138Wh/kg, Nissan Leaf pure electric early 24kWh version of the battery pack with a specific energy of ~110Wh/kg, Tesla Model S version of the specific energy of 156Wh/kg. In the "duty-free catalog", the ratio of energy >=120Wh/kg ratio of about 10%. Of course, there are also a number of directories in the 2015 and 2016 models than the energy of more than 150Wh/kg.          


From the PHEV of the driving mileage data, more than 60km models accounted for 56.9%, 70km accounted for more than 32.7%, with a total of 17.2% PHEV pure electric driving mileage reached more than 80km.          


Among them, in 2014 the battery pack than the average energy in the 72Wh/kg or so, in 2015 rose slightly to 74Wh/kg, in 2016 the growth is relatively large, reaching 90Wh/kg (Figure 4). BMW I8 battery pack energy ratio is about 72Wh/kg, volt battery GM package than energy about 88Wh/kg, the TOYOTA Prius PHEV 2013 version of the battery pack is about 55Wh/kg than energy. From a policy perspective, 50km pure electric mileage requirements also contributed to the PHEV of the battery pack energy to the general direction of development to meet a subsidy policy, which to some extent, also promoted the battery pack energy to enhance the development of the technology. more high density batteries like
