An introductory video to WindyNation’s soon to be released Windtura SuperAmp Alternator. The SuperAmp is a permanent magnet alternator (PMA) which we have specifically designed for high amp 12 volt battery bank wind turbine charging. If you want to see some serious amps, then watch this video.
Get the code from here:
A CCCV (Constant Current, Constant Voltage) is ideal for small batteries. Initially, the battery is charged at Constant Current. When the battery is nearly full, its voltage reaches the Constant Voltage setting of the charger, and the current decays exponentially as the battery gets a finishing charge.
In this model I have build a CCCV charger on simulink that simulates this effect can be used to study and simulate this charging method maybe in a bigger system.

I took a MOT and carefully stripped out the 2000V Secondary and replaced it with a low voltage high current winding of 18-20T or 12ga wire. New fully rectified DC output is 15.8VDC. An electrolytic capacitor of 1500uf was also added for smoothing purposes(Not much smoothing is required for charging lead acid batteries). Also includes a voltage monitoring circuit which allows you to know when the voltage of the battery being charged has reached completion. A green LED will be brightly illuminated to let you know to unplug the charger.
The circuit in the schematic above will connect to this automatic charging cut-off circuit, then to the battery to be charged:

An easy way to verify that your scooter’s charging system is functional if you’ve been having trouble with the battery being low. Also check out my battery check video to see if your battery is working properly :
Learn how to make a simple inductive battery charger for your NiMH/NiCd rechargeable batteries(2 to 4). The circuit in the video is for charging (2) batteries in series. This circuit operates in a very similar way as an ultrasonic toothbrush charger. The charging rate is slow(25-30mA), which can be made higher if desired, but it does charge well. The toothbrush charger uses a PWM IC to produce the high frequency pulses (75khz) into the primary winding with feedback to adjust the output under load, and this circuit uses a 555 IC to produce 42-46khz pulses into the primary winding to simplify the circuit. The transformerless power supply shown in this video is designed to power the exact circuit shown in this video. If you modify the primary winding and the circuit draws more current, then you will have to modify the transformerless power supply to deliver more current. You can also power the circuit using a very small 12V transformer. Don’t be afraid to experiment with different coils/windings!

DYSON DC34 vacuum battery verification (part of troubleshooting and repair)
Sometimes these appliances experience problems with batteries and/or charging. Dyson offers very prompt phone support, but the people on the phone do not get into very much detail when you describe the problems. They simply send you various replacement parts, one at a time. For the curious folks out there, here’s a video showing the charging of the battery using external means. If it charges this way, it’s highly likely that the charger (or its connector) is the source of your problem.
