Abstract

Battery management techniques for a vehicle include a set of sensors configured to measure a set of parameters of a battery of the vehicle and a controller configured to control recharging of the battery to a first target state of charge (SOC) corresponding to optimized battery life when a mileage of the vehicle is less than a threshold mileage corresponding to an expected transport period of the vehicle, wherein controlling the recharging of the battery to the first target SOC prevents battery malfunctions and thereby reduces vehicle warranty costs for an original equipment manufacturer (OEM) of the vehicle, and control recharging of the battery to a second target SOC determined by a cost-based optimization technique when the mileage of the vehicle reaches the threshold mileage.

First claim

What is claimed is:

1. A battery management system for a vehicle, the system comprising:
a set of sensors configured to measure a set of parameters of a battery of the vehicle; and
a controller configured to:
initiate a shipping mode of the vehicle during which the vehicle is expected to be in transport to a destination; and
during the shipping mode of the vehicle, control recharging of the battery to a first target state of charge (SOC) corresponding to optimized battery life when a mileage of the vehicle is less than a threshold mileage corresponding to the shipping mode, wherein controlling the recharging of the battery to the first target SOC prevents battery malfunctions and thereby reduces vehicle warranty costs for an original equipment manufacturer (OEM) of the vehicle;
end the shipping mode of the vehicle when the vehicle mileage reaches the threshold mileage; and
control recharging of the battery to a second target SOC determined by a cost-based optimization technique when the vehicle is no longer in the shipping mode.

2. The system of claim 1 , wherein the battery is a lithium ion (Li-ion) battery having the set of sensors integrated therein.

3. The system of claim 2 , wherein the first target SOC is 85-90%.

4. The system of claim 2 , wherein the Li-ion battery has a Lithium Iron Phosphate (LFP) composition, which provides for a higher first target SOC compared to an absorbent glass mat (AGM) battery.

5. The system of claim 1 , wherein the battery is an absorbent glass mat (AGM) battery, and one of the set of sensors is a voltage sensor integrated in the AGM battery.

6. The system of claim 5 , wherein the first target SOC is 80-85%.

7. The system of claim 1 , wherein the threshold mileage is 50 miles.

8. A battery management method for a vehicle, the method comprising:
measuring, by a set of sensors, a set of parameters of a battery of the vehicle;
initiating, by a controller of the vehicle, a shipping mode of the vehicle during which the vehicle is expected to be in transport to a destination;
during the shipping mode of the vehicle, controlling, by the controller, recharging of the battery to a first target state of charge (SOC) corresponding to optimized battery life when a mileage of the vehicle is less than a threshold mileage corresponding to the shipping mode, wherein controlling the recharging of the battery to the first target SOC prevents battery malfunctions and thereby reduces vehicle warranty costs for an original equipment manufacturer (OEM) of the vehicle;
end the shipping mode of the vehicle when the vehicle mileage reaches the threshold mileage; and
controlling, by the controller, recharging of the battery to a second target SOC determined by a cost-based optimization technique when the vehicle is no longer in the shipping mode.

9. The method of claim 8 , wherein the battery is a lithium ion (Li-ion) battery having the set of sensors integrated therein.

10. The method of claim 9 , wherein the first target SOC is 85-90%.

11. The method of claim 9 , wherein the Li-ion battery has a Lithium Iron Phosphate (LFP) composition, which provides for a higher first target SOC compared to an absorbent glass mat (AGM) battery.

12. The method of claim 8 , wherein the battery is an absorbent glass mat (AGM) battery, and one of the set of sensors is a voltage sensor integrated in the AGM battery.

13. The method of claim 12 , wherein the first target SOC is 80-85%.

14. The method of claim 8 , wherein the threshold mileage is 50 miles.
