First Claim
1. A system to manage battery performance of a vehicle, comprising:
- a battery management system of the vehicle comprising one or more processors and memory;
a database of the battery management system storing a profile for a battery of the vehicle;
a sensor of the vehicle to identify a value of a current output by the battery that supplies power to the vehicle;
a solid diffusion component of the battery management system to;
update, based on the value of the current and the profile, a solid concentration model of the battery;
an electrolyte transport component of the battery management system to;
update, based on the value of the current and the profile, an electrolyte concentration model of the battery;
an electrolyte and solid potential component to;
update, based on the value of the current and the profile, an electrolyte potential model of the battery; and
update, based on the value of the current and the profile, a solid potential model of the battery;
a battery controller component of the battery management system to;
determine, based on the solid concentration model updated by the solid diffusion component, the electrolyte concentration model updated by the electrolyte transport component, the electrolyte potential model updated by the electrolyte and solid potential component, and the solid potential model updated by the electrolyte and solid potential component, a value of a voltage of the battery and a value of a heat generation rate of the battery; and
generate, based on the value of the voltage of the battery and the value of the heat generation rate of the battery, a command to manage a performance of the battery.

Abstract
A vehicle battery controller based on a reduced order model is provided. The controller identifies a value of a current output by the battery that supplies power to the vehicle. The controller provides the value of the current to a solid diffusion component, an electrolyte transport component, and a electrolyte and solid potential component. The solid diffusion component can update a solid concentration model of the battery. The electrolyte transport component can update an electrolyte concentration model of the battery. The electrolyte and solid potential component can update an electrolyte potential model and a solid potential model of the battery. The controller component can determine a value of a voltage of the battery and a value of a heat generation rate of the battery. The controller component can generate a command to manage a performance of the battery.
