Battery overcharge monitoring system and method
First Claim
Patent Images
1. A battery charge monitoring method, comprising:
- calculating expected charge data for charging of a vehicle battery using at least a capacity of the vehicle battery, a charge rate, and an expected charge time;
during the charging, using a controller to compare actual charge data to the expected charge data to identify at least one difference between an actual charge time and the expected charge time, and at least one difference between an actual amount of energy used to charge the vehicle battery and an expected amount of energy required to charge the battery; and
ending the charging in response to the actual amount of energy to charge the vehicle battery exceeding the expected amount of energy required to charge the vehicle battery.

15. A battery charging system, comprising:
-
a battery charger to charge a vehicle battery; and a controller configured to selectively end a charge of the vehicle battery in response to an actual charge amount exceeding an expected charge amount, the expected charge amount calculated using at least a capacity of the vehicle battery and a charge rate, the expected charge amount including an expected amount of electrical charge used to charge the vehicle battery.

16. A battery charge monitoring method, comprising:
-
Comparing, using a controller, an actual charge time for a charge of a vehicle battery to an expected charge time for the charge of the vehicle battery; comparing an actual amount of charge used to charge the vehicle battery to an expected amount of charge used to charge the vehicle battery; ending the charge for the vehicle battery in response to a difference between the actual charge time and the expected charge time; and ending the charge of the vehicle battery in response to a difference between the actual amount of charge and the expected amount of charge. - View Dependent Claims (17)
