Abstract

The present invention relates to a battery target temperature method and system. Methods and systems for determining a target temperature and / or adjusting a temperature associated with a battery (eg, a vehicle battery). In some implementations of such methods, a temperature-scaled battery capacity of at least a portion of the battery may be determined at the measured temperature. The temperature-scaled battery capacity may be compared to a capacity threshold, and when the temperature-scaled battery capacity is determined to be below the capacity threshold, a target battery temperature for at least a portion of the battery may be determined and / or set.

Description

technical field [0001] The present disclosure relates to methods and systems for determining a target temperature and / or adjusting a temperature associated with a battery. For example, in some embodiments, the disclosure relates to methods and systems for determining a target temperature for a rechargeable energy storage system ("RESS") and / or adjusting the temperature of the RESS to improve vehicle efficiency. Background technique [0002] The range of an electric vehicle is typically proportional to battery capacity, so the range can vary greatly due to fluctuations in battery temperature. Accordingly, customers in certain geographic areas that experience cold temperatures and / or large temperature swings may potentially experience a variety of electric vehicle performance, such as electric vehicle range. For example, the same trip in a particular area with a vehicle having a RESS may vary considerably in range and / or depletion of battery charge on different occasions depe...
