High-power battery charger

I. Overview

Traditional and simple charging machines are typically composed of power frequency transformers and rectifying (or silicon-controlled rectifier voltage regulation) circuits, and even use silicon-controlled rectifiers to directly regulate household power for charging batteries. Although the circuit is simple, there are undeniable drawbacks:

Bulky for transportation, awkward to use.

Lack of comprehensive protection features; poor reliability.

Charging requires manual supervision and constant adjustment of the charging current, making it challenging to fully charge the battery without causing overcharging.

④ Directly regulating city power with silicon-controlled rectifiers poses a risk of electric shock due to non-isolation from city power, and it also damages the city power waveform and causes significant power line losses.

⑤ Portable design, sturdy and convenient.

2   Deep discharge, overcharge, and long-term undercharge of batteries can lead to premature aging of the battery plates, shortening the battery's lifespan. To prevent such occurrences and extend the battery's lifespan, the choice of a charger with different functional types becomes a crucial factor, especially when the equipment's power consumption characteristics and the matching battery remain unchanged. This is also why some users of traditional chargers report that the battery's lifespan is shorter than the manufacturer's specified lifespan.

This fully automatic charger employs the cutting-edge technology of non-sinusoidal transformerless switching power supply, featuring compact size, light weight, and high efficiency. It boasts high precision, low ripple, and is integrated with intelligent charging technology. Designed to extend the lifespan of lead-acid batteries and ensure timely charging, it addresses the shortcomings of conventional AC chargers. Compared to AC chargers, it significantly prolongs the lifespan of batteries, operates in a fully automatic, unattended mode, and is particularly suitable for unmanned charging scenarios. It can be connected to batteries for long periods to maintain a fully charged state, making it ideal for single battery charging in power stations and as an auxiliary power source and charging power for vehicles or generators.

This fully automatic charger is suitable for capacity12V and 24V open or fully sealed lead-acid batteries (sets) with capacities ranging from 20 to 1000 Ah, designed for配套 charging purposes, suitable for both temporary charging and long-term float charging.

Section II: Key Features

● Switching Power Supply Control Chips Utilize ImportedMilitary. Please provide the Chinese content to be translated.No Chinese content provided.The charger is designed with optimized principles, utilizing imported industrial-grade components for the rest of the components. The production process is strictly and perfectly refined, ensuring the reliability and stability of the machine.

● The charging program is meticulously designed according to the characteristic curve of battery charging, featuring a sequence of "(preset) constant current charging → (when reaching the equalizing voltage value) constant voltage with reduced current → (automatically switching to) floating charge." This program offers fast charging speed, high charging recovery efficiency, no need for manual supervision, no risk of overcharging during extended charging periods, and ensures the longevity of the battery.

The charging current can be selected in 10 steps ranging from 5A to 40A, and it is unaffected by fluctuations in the input AC voltage. During constant current charging, the current remains unchanged, eliminating the need for manual adjustment.

● 12V/24V battery automatic recognition: Simply connect a 12V or 24V battery to the charger's output, and the charger will automatically adjust its output voltage, eliminating the need for manual selection and preventing operational errors.

● Compatible with AC and DC input, featuring a wide voltage input range.

● Full-automatic Intelligent Protection Settings: Equipped with output short-circuit and battery polarity reverse connection protection, this feature utilizes electromagnetic air circuit breakers for protection, offering fast response and long lifespan. The machine also features intelligent temperature control fans for cooling and an automatic shutdown protection against overheating, ensuring users can safely and confidently use the product.

● The battery capacity is clearly displayed, making the status of the battery's charge level easily visible.

● Serving as a single battery supplement for power stations, it can also be used as an auxiliary starting power and supplementary charging power source for vehicles or generators and other equipment.
