DEFINITIONS 3.1 NORMAL CHARGING SYSTEM OPERATION Normal charging system operation includes an
13、alternator that generates electrical energy from a mechanical source, a voltage regulator to control the alternator output voltage, and a battery that provides a standby source of electrical energy. Further information on voltage regulators is found in SAE J2669, and on battery specifications is fou
14、nd in SAE J537 and SAE J930. 3.2 BATTERYLESS OPERATION Batteryless operation occurs in a machine application whenever the battery becomes disconnected from the alternator. The electrical load of the alternator is significantly different in this situation. The disconnection may be intentional or unin
15、tentional. In some applications, machines are shipped for export without batteries. In this situation, a slave battery may be used for jump starting the machine. After the machine is started, the battery is disconnected and the machine is moved. During movement the alternator is operating without th
16、e battery and expected to power such items as the engine control unit, transmission control unit, and engine fuel solenoids. Batteryless operation can also occur during operational usage whenever there is: a. A battery open cell failure b. The battery becomes extremely sulfated c. The connections to
17、 the battery become loose d. The connections to the battery become corroded e. A master disconnect switch becomes open or its connections become open The effect of the alternator operating in a batteryless situation is typically a wider range of voltages in output than when loaded with a battery. So
18、me alternators do not produce output without a battery or voltage regulation may become unstable.SAE J180 Revised MAY2012 Page 3 of 10 3.3 REVERSE POLARITY Reverse polarity occurs when the battery positive and negative cables are hooked up in reverse. This condition normally results in damage to the
19、 alternator and to any other semiconductor loads that experience the reverse polarity hookup. 3.4 LOAD DUMP A sudden interruption of most electrical loads from the alternator during alternator operation causes a self-induced voltage surge named load dump. Load dump could be caused by such items as c
20、onnections to the alternator B+ terminal becoming loose, connections to the alternator B+ terminal being corroded, defective alternator output cables, etc. The effect of a load dump is the presence of voltage spikes significantly exceeding system voltage and may exceed the voltage breakdown limits o
21、f some electrical components to cause damage. 4. PHYSICAL REQUIREMENTS 4.1 Dimensional Figure 1 portrays a spool-mount alternator. Figure 2 portrays a hinge mount alternator.
