The Cadillac Celestiq is Cadillac’s high end, luxury sedan. Like with most luxury EVs, the Celestiq features numerous technologies including smart glass roof, suspended particle devices, which alloes for four seperate dimmable interior zones. The biggest attraction will be the dual screen technology all under one single sheet of glass and the autonomous driving system. Recommendation: Given the battery and EV owners preference to charge quickly at home and keep your EV battery topped up as quickly possible to maximize your all electric range and reduce range anxiety, we would recommend a level 2 J1772 charger for your Cadillac Cellestiq. The NEMA 14-50 40 amp 9.6 kWh TOTALEV is our recommended EV charger as it is fastest, plug-in level 2 residential charger. Charge times are fast. From a 50% battery (in practice when most EV owners re-charge), the car will be fully charged in around 5 hours with a NEMA 14-50 40 amp 9.6 kWh Cadillac Cellestiq TOTALEV charger.
