For a li-ion battery to be used in a car beyond the year 2020, in a car that weighs about a tonne with a 100kw motor... what would the power requirement be for a range of 150-200 miles?
I understand the KW-h rating would depend on the current drawn by the motor, so if this mini had the following spec -
572-pound lithium ion battery
150 miles range per 8-hour charge
Consumption 4.4 miles/kWh
204-hp & 162 lb-ft of torque
0-60 bit over 8 seconds
Top speed limited to 95mph
A bit over 3,200 pounds
Lithium pack maximum capacity 35kWh.
Nominal 380 Volts to motor.
Contains 5,088 cells grouped into 48 modules
From looking around 150 seems like a very optimistic figure, so lets assume it has a 100 mile range... so what battery capacity would a car weighing a tonne with a 100kw motor require for an approximate range of 150-200 miles?
