Abstract: An apparatus for testing a storage battery in an automotive vehicle includes a controllable electrical load configured to electrically couple to the storage battery of the vehicle. A current sensor is configured to electrically connect to a terminal of the battery and measure flow of current through the battery. A controller is arranged to apply an electrical load to the battery using the controllable load and adjust the electrical load while monitoring the electrical current sensed by the current sensor to determine a charge current applied to the battery by an alternator of the vehicle and further configured to perform a test on the battery. A method for testing a storage battery in an automotive vehicle includes connecting a controllable electrical load to the storage battery, connecting a current sensor to a connection to a terminal of the battery, applying an electrical load to the battery using the controllable electrical load, adjusting the electrical load while monitoring an output from the current sensor to determine a charge current applied to the battery by an alternator of the vehicle, and performing a test on the battery.

Abstract: A battery maintenance device for performing maintenance on a battery pack of an automotive vehicle powered by the battery pack includes communication circuitry configured to retrieve information related to condition of batteries/cells of the battery pack obtained using sensors in the battery pack. Measurement circuitry couples to batteries/cells of the battery pack and obtains measurement information related to a measured condition of batteries/cells of the battery pack. A controller verifies operation of the sensors in the battery pack by comparing the retrieved information with the measurement and provides a comparison output. Output circuitry outputs an indication of a failing sensor in the battery pack based upon the comparison output.

Abstract: A clamp for providing an electrical connection to a battery includes a first arm, a second arm, a joint member, a first pivotable connection, and a second pivotable connection. The first arm includes a proximal end, a distal end, and an electrically conductive member at the distal end. The second arm includes a proximal end and a distal end. The first pivotable connection is between the joint member and the first arm, and defines a first axis, about which the first arm rotates relative to the joint member. The second pivotable connection is between the joint member and the second arm, and defines a second axis, about which the second arm rotates relative to the joint member. The first and second axes are displaced from each other in a direction that is perpendicular to the first axis.
