Hello,
I need a little advice, please, if possible.
I apologize—this is my first time working with a Tesla locked battery.
I received it from a customer without the car.
After the crash, it had some output voltage but no actual current being supplied.
I charged it to 16.1V, soldered wires to the board as shown in the picture, read the EEPROM with AST, saved it, cleared the crash data, and wrote it back. I did not disconnect anything from the battery.
I still see a phantom output voltage, but there’s still no current being supplied.
I tried briefly shorting the positive terminal from the cells to the positive output terminal, and also tried unplugging the balancer pigtail for a second—but the controller still won’t provide any output current.
Am I doing anything wrong or missing something?
Is it mandatory for the battery to be installed in the car in order for the controller to recognize the LIN signal and enable the output, or is there a way to wake up the controller on the bench without the actual car?
Thank you!
