    Charging: What can be communicated on the CCS chargers?

    I am wondering. Why do we need to have RFID fobs and apps etc. to charge our cars? When you plug in it just confirms that payment will be made. So the local motor department just sends a "1" and then it starts charging, and when done charging it requests payment. Then we just need to plug in...

    60V thundersky charger dead. New one/fix it?

    The big ones are only 200V capacitors. Why should the capacitors have the peak value of the AC? Found the problem. As i expected, the inductor has melted the connection directly under. Perfect! And it seems like the isolation of the conductor has also melted as you can see on the picture. Guess...

    60V thundersky charger dead. New one/fix it?

    I think that I have found something weird. The coil that both the fase and neutral goes through (green) I found that the connection between the primary side number 1 of the coil(red side), has good connection to its the AC leg on the rectifier(blue). This is the connection going through the two...

    60V thundersky charger dead. New one/fix it?

    Hello! I have a charger for my 60V40Ah pack, but it does not work at all. The lights wont even turn on. I have measure the coils/inductors on the board, and they all seem OK? I think that it could maybe be the rectifier transistor thing. The one on the board is this one...

    Hmm.. Thunderskyd/Ningbo 60V charger hacking?

    I'm trying to get schematics, but you, mayb impossible to fix. Could be nice if i could reprogram the microprocessor though :D Is it just rs232? You think i need a driver?

    Hmm.. Thunderskyd/Ningbo 60V charger hacking?

    It will turn on when it starts charging/when the current goes high. Why do you thint that it would be the culprit?

    Hmm.. Thunderskyd/Ningbo 60V charger hacking?

    Four months ago the charger got a problem with the electronics that controls the 12V fan, so I disassembled it and tried a couple of things without any luck. At the end I just shorted it out, so the fan always runs when the power is on :( Not optimal but it works. Anyways, I found some jumpers...

    LED bulbs does not work properly?

    I just bourght these two LED rear lights that does not work properly. If I connect both, they are extremely dim, and if I replace one with normal bulp, the LED does not work at all (Voltage drop?). If i connect to LAB PSU it works great with both brake light and normal light, but only brake...

    Google says it spends 0.0003 kWh of energy on a search query

    They know how many searches all users has done in one year, and then divide that number with their overall power consumption. Has nothing to do with how much energy one search costs. They also have gmail and youtube and etc.etc.etc.

    How to connect an alarm to battery?

    I'm going to connect a GPS alarm on my 60V scooter. Do i just find a random place where the voltage is 12V and then connect it? Or is there a better way? I guess it would be better with a 60V-12V converter, if that exists.

    Li-po/li-fe? Balancer. BMS

    I have just charged and discharged a pack of 5 x US15650FT dewalt cells and the imax B6 counts 957 Ah from 18V and down to 10V in discharge test. In the charge test from 10V to 18V it counted 1100 mAh dead on! They should be 1100 mAh :D They have been charged from 0 volt! They were 0 volt for...
