According to Cadillac’s website, at public Level 2 charging stations, Lyric can charge up to 60A for AWD models, and up to 100A for RWD models.

Level 2: Faster than Level 1. Requires a 4-prong (240v) wall outlet or 240v hardwired charging unit installed by a professional electrician. Level 2 charging is the most frequently used type of charging for EV drivers. Adds up to 37 miles of range per hour of charging with a 60A/240v power source (MY23 AWD models) or up to 52 miles of range per hour of charging with a 100A/240v hardwired charging unit (MY23 RWD models). Level 2 uses a J1772 connector. The In-vehicle Maps app labels these locations as “Fast.”

 

These are the maximum speed supported by Cadillac, usually at a public level 2 charger. It is uncommon to have such condition at home, and there is no need to charge at the maximum speed, as these high current circuits can be very expensive and hard to install at home.

To charge at 60A, you need a dedicated 75A circuit.

To charge at 100A, you need a dedicated 125A circuit.

 

Cadillac comes with a Dual level Charging Cord for home use, which goes up to 32 Amps (240V)

It comes with a NEMA 14-50 plug for 240V level 2 charging, and a regular 120V plug for level 1 charging.

This means this EVSE is not compatible with Splitvolt Splitter Switch, SPS 01-031-01 and SPS C2-032, as it will trip the breaker, typically within 1hr.

Since there is no way to change the charge rate from the car or the EVSE, the recommended configurations are:

  • If sharing a circuit with dryer:

    • use a Splitter Switch SPS C1-011 or SPS C2-022 model with any 3rd party 24 amps EVSE ( such as splitvolt’s mobile charging cables). This will allow the maximum amount of current (24 amps, 5.7kw) to be pulled from a 30 amps dryer circuit.

  • If there is a dedicated 30 amps circuit, with NEMA 14-30 or 10-30 socket, then purchase any 3rd party 24 amps EVSE ( such as splitvolt’s mobile charging cables). This will allow the maximum amount of current (24 amps, 5.7kw) to be pulled from a 30 amps dryer circuit.

  • If there is a dedicated 40 or 50 amps circuit, with a NEMA 14-50 socket, then the manufacture’s EVSE is ready to use.
