How to wire a 13Amp UK plug for a type 2 electric vehicle charging cable?

I was in the same boat but I cut the plug off very carefully then used a gel filled waterproof conector to extend the cable so I didn't cut the small wires they looks to be something on the end but ...

Effect of temperature on battery charging

Is it worth it getting a temperature-sensor for the solar charge-controller? Or is it somewhat of a gimmick so they can make some extra money on selling the sensor? Spoiler and Short answer: I ...

Effect of temperature on battery charging

While I can’t directly speak to the “worth” of outfitting a specific system with a temp sensor (as I have no experience with solar-battery systems) I can tell you that lead acid batteries are ...

A capacitor charge time - two methods two different answers

Your problem, as stated, is overconstrained. If you know V=50V and I=50A, the ESR has to be 1 ohm at t=0 and drop gradually over time as the capacitor stored voltage increases. If we choose to assume ...

A capacitor charge time - two methods two different answers

The problem is already the following assumption: A theoretical Capacitor of 100 F is being charged with a constant power source of values V = 50V, I = 50A, ESR of Cap = 5 mOhm The voltage at the ...

A capacitor charge time - two methods two different answers

you are neglecting ESR losses in your conservation of energy equations. Charging a cap or battery is never "constant power" unless V*I= constant, which is not the case with CC for a cap ...

A capacitor charge time - two methods two different answers

Your time constant of 0.5 seconds clearly is derived from your capacitor ESR of 5 mohm. So, what you are effectively proposing as a charge circuit looks like simulate this circuit – Schematic ...
