Abstract

Methods and systems are provided for calibrating one or more limits of a battery of a vehicle, the battery having state of charge limits and power limits. A history of environmental conditions for the vehicle is obtained and stored in a memory. One or more of the state of charge limits, one or more of the power limits, or both are adjusted based on the history of environmental conditions and usage severity using a processor.

Description

technical field [0001] The present invention relates generally to the field of vehicle batteries, and more particularly to methods and systems for calibrating the state of charge and / or power limit of a battery of a vehicle, such as in an electric or hybrid electric vehicle. Background technique [0002] Certain vehicles, particularly electric vehicles and hybrid electric vehicles, utilize batteries (eg, battery packs) to generate power. Batteries include various battery cells therein. Batteries typically operate within preset state of charge and power limits for the vehicle. To ensure battery life under all conditions, state of charge and power limits are typically preset based on worst case scenarios of environmental and operating conditions. However, such typical technologies do not provide vehicles with optimal battery performance or fuel savings in certain situations, such as in relatively mild climates or moderate usage. [0003] Accordingly, there is a need to prov...
