[0014] It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this application belongs.

[0015] See also Figure 1 The present invention provides an emergency generator main battery charging and control system power supply unit, including: a main battery charger, a battery voltage monitoring module, a main battery, an uninterruptible power supply (UPS) and a secondary battery.

[0016] The main battery charger's L and N terminals are equipped with a pushbutton switch SB1 and a safety switch F1. The positive and negative terminals of the main battery charger's OUT terminal are connected to the main battery. The main battery stores energy for starting the emergency generator. The main battery charger provides a stable charging current and voltage for the main battery. A battery voltage monitoring module is connected between the positive and negative terminals of the main battery charger's OUT terminal. This module continuously monitors the main battery voltage and issues a signal when the voltage falls below a set value.

[0017] A diode is connected to the positive terminal of the main battery charger's OUT terminal. This reverse diode prevents reverse current surges during charging, thereby protecting the main battery charger. An ammeter is installed at the positive terminal of the main battery charger's OUT terminal, which displays the charging current and helps monitor the charging status. A voltmeter is connected between the positive and negative terminals of the main battery charger's OUT terminal to monitor the voltage during charging and ensure it remains within a safe range. The battery voltage monitoring module is connected to the AMS alarm.

[0018] The UPS provides a stable and reliable power supply in emergency situations, ensuring continuous operation of the control system. The UPS input terminal is equipped with a safety switch F2, and the UPS output terminal is equipped with a safety switch F3 and a pushbutton switch SB2. A secondary battery is connected to the UPS to provide power to the UPS. Pushbutton switch SB2 is connected to the emergency generator control box.

[0019] The working principle of the power supply unit for the main battery charging and control system of an emergency generator provided by the embodiment of the utility model is as follows: the main battery charger provides 24V DC power to the main battery. The voltmeter monitors the charging voltage in real time to ensure that it is within a safe range. The ammeter measures the current flowing through the battery through the shunt tube to monitor the charging intensity. The reverse diode prevents the reverse current of the battery from damaging the charger. The battery voltage monitoring module detects the voltage of the main battery and sends a signal when the voltage is too low, which may trigger the main battery charger to start or stop. The UPS provides power in an emergency to ensure the stable operation of the control system.

[0020] In summary, the embodiment of the present invention provides an emergency generator main battery charging and control system power supply unit with a simple design and readily available materials. Users can select the appropriate charger and UPS based on their needs and budget, improving flexibility and cost-effectiveness. The main battery charger outputs 24VDC to the battery, and the output line is equipped with various reverse-connected diodes, a voltmeter, a shunt, an ammeter, and a battery voltage monitoring module. The voltmeter and ammeter monitor the charging voltage and current; the diode prevents the main battery from reversely impacting the charger and causing damage; and the battery voltage monitoring module monitors whether the main battery voltage is too low. If the monitored battery voltage is lower than the normal value, it will issue a switch point signal, signaling the control system power supply to the UPS output to ensure stable and reliable power supply. This emergency generator main battery charging and control system power supply unit has a simple structure and is made of common, readily available materials. The main battery charger and UPS can be purchased from the market to suit their brand, capacity, and price.
