EV Charger Progress

• Worked out adjustment of circuit (potentiometer wrong on breadboard).
• Tried the "off" circuit ... and fried a transistor (darn !)
• Therefore - definitely decided to use Optocoupler.
• Read all about optocouplers (see seperate post, under subject "Optocouplers")
• Ordered 40,000 count multimeter (to accurately set charger, and balance circuits).
• Ordered terminal blocks, and opto-couplers.
• NOTE - PCB board was too expensive. Almost half price at Jaycar.
• Started work on new PCB for balance circuit.
