VEHICLE ENERGY MEASUREMENT SYSTEM

摘要

An electric vehicle battery energy level is calculated by measuring acceleration, load, speeds, and/or changes in elevation (motion measurements) 330 that the vehicle 104 experiences during operation. By correlating motion measurements of a field vehicle to motion measurements of a test vehicle during operational profile testing, the amount of energy consumed out of the field vehicle battery is calculated 340. The amount of energy consumed is then compared with the battery's initial energy level 350 resulting in the calculation of an electric vehicle battery energy level without directly measuring the actual current drawn out of the battery.
