Electric vehicles (EVs) are becoming increasingly popular, and with that comes the need for more efficient and convenient charging solutions. One of the latest advancements in EV technology is the 19.2 kW onboard charging module.
Understanding Onboard Charging Modules
An onboard charging module (OCM) is an essential component of an EV’s charging system. It converts alternating current (AC) electricity from a charging station or outlet into direct current (DC), which is then used to charge the vehicle’s battery.
Benefits of a 19.2 kW Onboard Charging Module:
- Faster Charging: A 19.2 kW OCM can charge an EV’s battery at a significantly faster rate than a standard 11.5 kW OCM. This can be particularly beneficial for those who frequently travel long distances or need to charge their vehicle quickly.
- Vehicle-to-Home (V2H) Capabilities: A 19.2 kW OCM may support V2H capabilities, allowing the vehicle’s battery to power the home during power outages or grid emergencies.
19.2 kW Onboard Charging Module for the Cadillac Lyriq
The 2024 Cadillac Lyriq is the first production vehicle to offer a 19.2 kW OCM as an option. This advanced charging module provides a range of benefits for Lyriq owners.
Charging Considerations:
- Road Trips: On road trips, the Lyriq’s 190 kW DC fast charging capability is more efficient than AC charging. AC chargers are only practical for overnight stays with extended charging time.
- Home Charging: A 11.5 kW charger provides ample charging capacity for most home charging needs. However, a 19.2 kW charger is recommended for faster charging or future V2H support.
- Electrical Requirements: The 19.2 kW charger requires a 100 Amp breaker and AWG 3 wire, necessitating professional installation. It is essential to ensure that the home’s electrical service can support the additional load.
Additional Considerations
- CCS1 Charging Connector: The Lyriq uses the CCS1 charging connector, which is compatible with most public charging stations. Adapters are available for Tesla Destination AC Chargers.
- Charging Rates: As the battery state of charge increases, the charging rate typically slows down. Overnight charging at reduced electricity rates can be an economical option.
- Professional Consultation: Professional electrical consultation is recommended for any major electrical upgrades related to home charging.
In conclusion, the 19.2 kW onboard charging module is a significant advancement in EV charging technology. It offers faster charging times, potential V2H capabilities, and enhanced flexibility for Cadillac Lyriq owners. By understanding the benefits and considerations associated with this module, you can make informed decisions about your EV charging needs.
