    Hi all,

    I need some help from the community, we are looking for someone who has stuck an oscilloscope onto the charger during the charging phase and knows the tolerance that Tesla uses for the Voltage and current ripple on its chargers?

    We know that the SAE and CHAdeMO standard is usually +/-1% ripple for current and voltage but we cannot find the technical standards of what Tesla charges at.

    If anyone has any technical documents on how Tesla does its charger comms handshake and what tolerances their chargers operate at I would be greatful.

    From my understanding the car and charger follow the J1772 signaling specification for AC level 1 and 2 charging. I don't know if anyone aside from Tesla and the manufacturer of their High Power Wall Charger would have the exact tolerance information but it is safe to assume it is within any tolerances of the SAE J1772 specifications.
