Pure digital smart charger
Product manual
Product introduction
The electric adopts pure digital DSP chip, built-in advanced 3p3z loop algorithm, with fast
Small size, stable charging, high efficiency, safe and reliable, etc., can be used for floating charge, constant current, constant voltage,
Various charging strategies, including input overvoltage, input undervoltage, double overtemperature, battery reverse connection, output short circuit,
The first is the over-energy zero protection function.
The DC output terminal of the charger is connected to the positive and negative poles of the power battery, and the AC input terminal is connected to the AC 220V mains to power the charger, thus realizing the function of replenishing the battery pack.
The product has the following characteristics:
-
Pure digital DSP chip, built-in advanced 3p3z loop algorithm, fast response speed and precise curve control:
-
Adopting the optimized pure digital 3p3z constant voltage and constant current dual loop algorithm, the calculation is completed within a single PWM cycle. Compared with the traditional PID algorithm, it greatly improves the dynamic response speed of the system, helps to reduce the voltage and current stress of the power components, and improves the reliability of the product;
-
Conform to the standard charging characteristic curves of various batteries;
-
Automatic control of high-speed fan switch effectively extends service life;
-
Automatic protection measures for short circuit, overcurrent, overvoltage, overtemperature, reverse connection, etc.
-
Reasonable structural design, fast heat dissipation and good stability;
-
Small size, light weight, easy to carry and simple to use.
Charging process description
-
Connect cables
-
Connect the battery to the output end, and then connect the AC 220V power supply to the input end. The charger will automatically detect the battery parameters. If the battery voltage exceeds the corresponding setting or the polarity is reversed, the user will be prompted through the indicator light and all operations will be stopped. If everything is normal, the charger will enter the charging stage.
-
Charging
The battery is charged in a formal process such as constant current, constant voltage, and trickle current according to the selected curve.
- Charging ends
The charger stops charging the battery, and the charging status indicator lights at 25%, 50%, 75%, and 100% are always on. After being fully charged, the battery can be connected to the charger for a long time without human intervention.
Note: The fan will automatically turn on during charging and stop when charging is complete.
It’s pretty solid. If you don’t like fan noise this isn’t for you. I thought I was going to be able to select the amps and the voltage so having it auto is a bit of a downer but not a buzz kill.
One charger to rule them all is pretty cool.
