Set forth herein are systems and methods for determining battery heating conditions and pre-heating lead times of at least a minute or more, based on input parameters and sets of input parameters, to predictively and dynamically heat a secondary battery so that the battery has a specific power output and performance level when used in an electric or hybrid vehicle application.

Battery thermal management system and methods of use

This patent application is directed to thermal management systems of vehicles with an electric powertrain. More specifically, the battery system and one or more powertrain components and/or cabin climate control components of a vehicle share the same thermal circuit as the battery module through which heat can be exchanged between the battery module and one or more powertrain or climate control components as needed.

Thermal management system for vehicles with an electric powertrain

Provided herein are apparatuses and methods of useful for managing pressure in electrochemical devices. The methods and systems use inputs and combinations of inputs to predictively pressurize or depressurize a battery. The methods minimize energy losses from excessive battery pressure when the battery is not in use.

Active and passive battery pressure management

Set forth herein are systems and methods for determining when to heat a battery, and under what conditions to do so, The methods include using input parameters to predict when to heat a battery and how to heat that battery. For example, the methods predict when to heat a battery so that the battery has a specific power output and performance level when used in an electric or hybrid vehicle application.
