1. A system for modifying a vehicle battery temperature, comprising:
- a vehicle battery system comprising at least one vehicle battery, the vehicle battery comprising a plurality of battery sections;
a battery temperature sensor configured to sense a temperature of at least a portion of the vehicle;
a battery conditioning system configured to receive information from the battery temperature sensor and modify a temperature of at least one section of the plurality of battery sections of the vehicle battery system,wherein the battery conditioning system is configured to separately calculate a temperature-scaled battery capacity of a first section of the plurality of battery sections and a second section of the plurality of battery sections using one or more temperatures measured by the battery temperature sensor,wherein the battery conditioning system is configured to compare the temperature-scaled battery capacity of the first section with a first capacity threshold,wherein the battery conditioning system is further configured to compare the temperature-scaled battery capacity of the second section with a second capacity threshold, wherein the first capacity threshold differs from the second capacity threshold, andwherein the battery conditioning system is configured to, upon determining that the temperature-scaled battery capacity of at least one of the first section and the second section is below the capacity threshold, determine a target battery temperature for at least one of the first section and the second section of the plurality of battery sections of the vehicle battery system.

Abstract
Methods and systems for determining a target temperature and/or adjusting a temperature associated with a battery, such as a vehicle battery. In some implementations of such methods, a temperature-scaled battery capacity of at least a portion of a battery may be determined at a measured temperature. The temperature-scaled battery capacity may be compared with a capacity threshold and, upon determining that the temperature-scaled battery capacity is below the capacity threshold, a target battery temperature for the at least a portion of the battery may be determined and/or set.
