摘要： A test system for a battery pack having at least first and second battery modules is provided. The system includes a high voltage service disconnect assembly having a housing and an electrically-actuated switch. The system further includes a microprocessor that generates a first signal to induce the switch to have a closed operational position to electrically couple the first battery module to the second battery module. The sensor generates a second signal associated with the battery pack. The microprocessor stops generating the first signal to induce the switch to have an open operational position to electrically decouple the first battery module from the second battery module when the first signal is greater than a threshold level.

摘要： Systems and methods are disclosed for detecting whether a battery in an electronic device is counterfeit or defective. An actual battery characteristic profile is generated by recording the performance of the battery during use of the battery by the device. This profile is then compared to its corresponding expected characteristic profile. If the profiles are not substantially similar (i.e. if the error between the two curves exceeds a given error threshold), the battery is determined to be counterfeit or defective and responsive action is taken.

摘要： Leakage current between two electrical energy sources in a vehicle, one of which is normally isolated from ground, can be detected and measured by connecting voltage dividers across the two sources. The center node voltage of the first voltage divider, connected across a first battery, is measured. Thereafter, the center nodes of both dividers are connected to each other and the center node voltage of both dividers is measured and compared to the first voltage obtained from the first divider. A difference between the two voltages indicates a leakage current from the second battery to ground.
