[#SmartGrid #スマートグリッド] EV車載電池の比較、充電時間、耐久性、等かなり異なる仕様



公表値と実際に計測した実測値にかなり開きがある、という事が興味深いデータである。 特に寒冷地での性能劣化は今後の普及に対して大きく注目すべき過大になるのでは、

車種 電池技術 公表値 実証値
BMW Mini E 35 kWh lithium ion. Air cooled. Range: 156 miles (ideal conditions), 109 miles (normal city driving), 96 miles (normal highway driving). Charge time: 26 hours at 110V/12 amp outlet. 4.5 hours at 240V/32 amp. 3 hours at 240V/48 amp. Drivers in BMW’s demo fleet have gotten closer to 100-110 miles per charge. In below-freezing temperatures, range has dropped in some cases to 55-80 miles.
Chevy Volt 16 kWh (plus 1.4L gas engine). Liquid cooled. Lithium manganese cells from LG Chem. Electric range: 40 miles. Total range: “Hundreds of miles.Charge time: 10 hours at 120V, 4 hours at 240V. Former GM Vice Chairman Bob Lutz has said he got 28 miles worth of juice from the battery when he drove a Volt for a weekend in Detroit last winter, explaining that the car’s range, “can vary on any given day depending on temperature, terrain, driving conditions and so forth.”
Coda Sedan 34 kWh Range: 90-120 miles. Charge time: <6 hours at 240V. Expect data to start rolling in later this year when the car launches in California.
Fisker Karma 22.6 kWh (plus 2.0L gas engine). Lithium ion cells from A123 Systems. Electric range: 50 miles. Total range: 300 miles. Unknown. Expect more info during the next six months, as the Karma’s slated to launch in September 2010. As with the Tesla Roadster, Karma drivers tempted by the model’s sports car aspects may sacrifice some electric range for sportier performance.
