Features of fast charging circuit

1. After the output voltage is set (for example, 36V), if it is replaced by the rechargeable battery plate, causing a certain set of batteries to be blocked or short-circuited, the battery terminal voltage will decrease or be zero, and the charger will have no output current. .

2. If the voltage of the charged battery is rated and set voltage, such as the set voltage is 36V, 24V, 12V, 6V battery, etc., the charger has no output current, if it is set to 24V, the battery is incorrectly connected to 36V, and the charger is The output voltage is lower than the battery voltage, so the battery cannot be charged either.

3. If the two output terminals of the charger are short-circuited, since the trigger circuit of the SCR in the charger cannot work, the SCR does not conduct and the output current is zero.

4. If the positive and negative poles of the battery are incorrectly connected during use, the thyristor trigger circuit will continue in the reverse direction, there will be no trigger signal, the thyristor will not conduct, and the output current will be zero.
5. The use of pulse charging is beneficial to prolong the life of the battery. Since the low-voltage alternating current is pulsating DC after full-wave rectification, the thyristor will be turned on only when its peak voltage is greater than the battery voltage, and when the pulsating DC voltage is in the valley area, the thyristor will reversely bias and stop to stop the Charging, so pulsating direct current flows through the battery.

6. Fast charging, automatic stop when full. Since the voltage at both ends of the battery is low at the beginning of charging, the charging current is relatively large. When the battery is about to be full (36V battery terminal voltage can reach 44V), as the charging voltage is getting closer and closer to the peak value of the pulsating DC output voltage, the charging current will become smaller and smaller, and it will automatically become trickle charging. When the voltage across the battery is charged to the peak value of the rectified output, the charging process stops. After testing, three electric vehicle batteries 36V (12V/12Ah three in series) can be fully charged with the charger in just a few hours.

7. The circuit is simple, easy to make, almost no maintenance and repair.

How long does it last for laptops? What's the price?

These products look really good, I just want to know how the prices are, they don’t look cheap

How much?

very beautiful
