Abstract
This disclosure details thermal management systems for thermally managing electrified vehicle components. An exemplary thermal management system may be configured to direct a coolant through a battery bypass loop that bypasses a traction battery pack based on an amount of heat rejection into the coolant from a water charge air cooler.
Claims19
A thermal management system, comprising:
- a traction battery pack;
- a coolant subsystem configured to circulate a coolant through the traction battery pack,
- wherein the coolant subsystem includes an air cooler loop and a battery bypass loop;
- a water charge air cooler positioned within the air cooler loop;
- a valve arranged to control a flow of the coolant to either the traction battery pack or the battery bypass loop;
- and
- a control unit configured to control a position of the valve based on an amount of heat rejection into the coolant from the water charge air cooler,
- wherein the coolant subsystem includes a T-joint configured to divide the coolant between a first portion that is directed to the water charge air cooler and a second portion that is directed to the valve.

A method, comprising:
- allowing or preventing a flow of a coolant to a traction battery pack within an electrified vehicle thermal management system based on an amount of heat rejection from a water charge air cooler into the coolant,
- wherein a valve is arranged to control the flow of the coolant to either the traction battery pack or a battery bypass loop,
- wherein a T-joint is configured to divide the coolant between a first portion that is directed to the water charge air cooler and a second portion that is directed to the valve.
A thermal management system, comprising:
- a traction battery pack;
- a power electronics module;
- a coolant subsystem configured to circulate a coolant through the traction battery pack and the power electronics module,
- wherein the coolant subsystem includes an air cooler loop and a battery bypass loop;
- a water charge air cooler positioned within the air cooler loop,
- wherein the water charge air cooler is part of an engine system that includes a turbocharger and an internal combustion engine,
- wherein the coolant exchanges heat with an airflow from the turbocharger within the water charge air cooler;
- a valve arranged to control a flow of the coolant to either the traction battery pack or the battery bypass loop;
- and
- a control unit programmed with instructions for controlling a position of the valve based on an amount of heat rejection from the airflow to the coolant while the coolant is passed through the water charge air cooler,
- wherein the valve is positioned immediately upstream of an inlet of the traction battery pack, and an outlet of the battery bypass loop is positioned immediately upstream of an inlet of the power electronics module.
