Systems and methods for determining a warranty obligation of a supplier to an original equipment manufacturer for a vehicle battery pack

A method for determining a warranty obligation of a supplier to an OEM relating to a vehicle battery pack of a vehicle, the vehicle battery pack being previously purchased by the OEM from the supplier, the method comprising:

• retrieving a stored operational parameter associated with at least one component of the vehicle battery pack or a battery management system from a memory device of the battery management system, utilizing a computer;
• determining whether the operational parameter is greater than a threshold value, if the vehicle battery pack has degraded performance due to the component and the vehicle battery pack is replaced by the OEM with a replacement battery pack;
• and
• reimbursing the OEM or crediting a financial account associated with the OEM for at least a portion of the cost of the replacement battery pack by the supplier if the operational parameter is greater than the threshold value and the vehicle battery pack has degraded performance due to the component and the vehicle battery pack is replaced by the OEM with the replacement battery pack.

A method for determining a warranty obligation of a supplier to an OEM relating to a vehicle battery pack of a vehicle, the vehicle battery pack being previously purchased by the OEM from the supplier, the method comprising:

• retrieving a stored event code associated with an event that has occurred in the vehicle battery pack or has occurred in the vehicle from a memory device of a battery management system, utilizing a computer;
• determining whether the stored event code corresponds to a predetermined event code, if the vehicle battery pack has degraded performance due to the event and the vehicle battery pack is replaced by the OEM with a replacement battery pack;
• and
• not reimbursing the OEM or crediting a financial account associated with the OEM for at least a portion of the cost of the replacement battery pack by the supplier if the stored event code corresponds to the predetermined event code and the vehicle battery pack has degraded performance due to the event associated with the event code and the vehicle battery pack is replaced by the OEM with the replacement battery pack.

• retrieving a stored operational parameter associated with at least one component of the vehicle battery pack or a battery management system from a memory device of the battery management system, utilizing a computer;
• determining whether the operational parameter is within a predetermined operational parameter range, if the vehicle battery pack has degraded performance due to the component and the vehicle battery pack is replaced by the OEM with a replacement battery pack, the predetermined operational parameter range having an upper threshold value and a lower threshold value;
• and
• reimbursing the OEM or crediting a financial account associated with the OEM for at least a portion of the cost of the replacement battery pack by the supplier if the operational parameter is within the predetermined operational parameter range and the vehicle battery pack has degraded performance due to the component and the vehicle battery pack is replaced by the OEM with the replacement battery pack.
