The intelligent battery charger can automatically adopt constant current fast charging, trickle floating charging, and automatic stop charging when fully charged according to different conditions of the battery voltage. At the same time, the diesel intelligent battery charger has automatic overcurrent and short circuit protection functions. Compared with the commonly used floating chargers in the industry, battery chargers have the advantage of avoiding battery damage and extending service life. Widely used in railway, civil aviation, communications, and power.

Main functions and features:

· The input AC voltage range is wide, and the output DC stability is good.

· The output current is continuously adjustable.

· Flexible use: It can be charged by a single unit or multiple units in parallel without current sharing.

· Equipped with input, output over-current, over-voltage, under-voltage protection, and over-heat protection for the entire machine.

· Flexible adjustment according to different specifications of batteries and battery packs

In the mid 1960s, the American battery expert Mars researched the best charging technology of the battery, and proposed an acceptable charging current curve for the battery based on the lowest gas evolution rate. . That is, the current is very large at the beginning of charging. As the battery voltage continues to rise, the charging current continues to decrease until it is fully charged. At this time, the charging current approaches zero. Then automatically switch to constant voltage charging to maintain the loss of battery self-discharge. This charging method can be greatly extended

First, 1, charging voltage 2, charging current

Second, choose the rated power, voltage and current of the transformer

Third, the necessary rectification, current limiting, voltage regulator circuit components must reach the maximum voltage and current indicators of the load.

For batteries, the charger was the earliest transformer-type charger. However, transformer transformer chargers are rarely used due to their large size, bulk, low cost, and low charging efficiency. Electronic chargers are widely used. The input AC voltage of the charger is about 220V, and the output terminal is connected to the battery, and its charging method;

First, intermittent discharge and compensation with high-current pulse charging; and second, constant current and constant voltage floating charging are used to maintain a stable charging voltage and current for the charged battery. The charger has output short circuit protection, output overvoltage, overcurrent protection and overshoot protection functions to ensure the battery life.

Due to the development of fast charging technology, the concept that the traditional lead-acid battery has poor fast charging performance has undergone new changes. Experiments show that most valve-regulated lead-acid batteries can withstand rapid charging, and reasonable rapid charging is not only harmless and beneficial to extend battery life.
