METHOD AND APPARATUS FOR DETERMINING THE STATE OF CHARGE OF A LITHIUM-ION BATTERY

摘要

Computer-assisted methods for determining the state of charge of a specific lithium ion battery (100), without the need for charging and discharging the battery, by utilizing look-up tables or algorithms, within a computer (1) which store the relationships of state of charge to open-circuit voltage or to ramp-peak current, or to both for that type of specific lithium-ion battery (100) to determine the state of charge for that specific lithium-ion battery (100).
