The battery mainly provides energy. After a successful start, the diesel engine drives a small generator with 28V DC output to charge the battery. Some units do not have this small generator and the 380/220 V AC power provided by the. the generator passes through The charger charges the battery.
Now the battery is dead. There are several reasons. If the diesel generator is not used for a long time, the battery will run out because it cannot be charged in time, because the battery itself will discharge automatically. Therefore, for batteries that are not used normally, the battery should be used. be recharged at least once a month until bubbles are generated in the battery. The diesel engine The battery must be charged for at least half an hour after each start of the group.
For frequently used units, it is necessary tocheck if the charging generator or charger is defective. The charging generator must have a voltage output of 28 V DC and the minimum must not be less than 27 V.
In addition, associated charging circuit failures will also prevent the battery from charging , which will cause battery power failure.
Another reason is that the battery itself is damaged. In this case, the battery can be recharged for 24 hours. If it is still discharged, replace it with a new one.
One thing is for sure, low battery voltage will affect engine starting, so it is necessary to ensure that the battery voltage is sufficient. As for an external charger, this is just one of the methods. An external charger can be connected, provided that the rating of the external charger must meet the charging needs of the battery, such as output power, output voltage and output current.
