Abstract
A system and method for performing a vehicle battery test includes a battery tester having a controller programed to obtain a first battery parameter and a second battery parameter of a primary battery from a vehicle controller, compare the first battery parameter to a first threshold, compare the second battery parameter to a second threshold and perform a reserve charge test on the battery using the battery tester or generating a display indicative of high corrosion or a bad cell in response to the compare the first battery parameter and compare the second battery parameter steps being performed by the controller.
Claims15
A battery tester for testing a primary battery of a vehicle comprising;
- a controller programed to perform the steps of
- obtain a state of health and an internal resistance of the primary battery from a vehicle controller;
- compare the state of health to a first threshold;
- compare the internal resistance to a second threshold;
- and
- perform a reserve charge test on the battery using the battery tester when the state of health is above a first threshold and the internal resistance is below a second threshold and generating a display indicative of high corrosion or a bad cell when the state of health is below the first threshold and the internal resistance is above the second threshold.
The method of testing the primary battery as recited in 1 wherein the internal resistance comprises a multiple of a production internal resistance.
A method of testing a primary battery comprising:
- coupling a battery tester to terminals of the primary battery of a vehicle;
- coupling the battery tester to a vehicle controller in the vehicle;
- communicating a state of health of the primary battery and an internal resistance of the primary battery from the vehicle controller to the battery tester;
- comparing the first battery parameter state of health to a first threshold;
- comparing the internal resistance to a second threshold;
- and
- in response to the state of health being above a first threshold and the internal resistance below a second threshold, performing a reserve charge test to determine a reserve capacity of the battery using the battery tester;
- and
- when the state of health is below the first threshold and the internal resistance is above the second threshold generating a display indicative of high corrosion or a bad cell.
