Abstract
Aspects of the disclosure include systems and methods for leveraging a thermally triggered adhesive release for battery service. An exemplary method can include receiving a battery pack having an adhesive layer at an interface between a cooling plate and a component. A heating fluid is directed through an enclosed volume of the cooling plate and a temperature of the adhesive layer is measured. Responsive to determining that the temperature has reached a target temperature, a load is applied to the component until the component is removed.
Claims20
A vehicle comprising:
- an electric motor;
- a battery pack electrically coupled to the electric motor;
- and
- a thermal management system coupled to the battery pack, the thermal management system comprising a cooling plate, an upper tray, and a lower tray joined to opposite surfaces of the cooling plate to define an enclosed volume therebetween, the thermal management system further comprising:
- a memory, computer readable instructions, and one or more processors for executing the computer readable instructions, the computer readable instructions controlling the one or more processors to perform operations comprising:
- modifying at least one of a flowrate and a temperature of a heating fluid through the enclosed volume;
- measuring a temperature of an adhesive layer coupled to the cooling plate and a component of the battery pack;
- and
- responsive to determining that the temperature has reached a target temperature, applying a load to the component until the component is removed.
