Abstract:
An apparatus for testing an alternator in a battery-based electrical system, the apparatus comprising:a voltage sensor for adapted for attachment to the battery-based electrical system for measuring voltage of the battery-based electrical system; a charging current sensor adapted for attachment to the battery-based electrical system for measuring current charged to the battery-based electrical system; a discharging current sensor adapted for attachment to the battery-based electrical system for measuring current discharged from the battery-based electrical system; a variable power supply adapted for attachment to the battery-based electrical system for varying the charging conditions of the battery-based electrical system; a variable load adapted for attachment to the battery-based electrical system for varying the discharging conditions of the battery-based electrical system; and a system controller for use in controlling the variable power supply and load and for measuring the current and voltage generated by the alternator under the varying charging and discharging conditions of the battery-based electrical system.
