Cadillac Lyriq Charging Calculator

What Is the Cadillac Lyriq Charging Calculator?

The Cadillac Lyriq Charging Calculator is a tool designed to estimate charging times and costs based on battery capacity, charge levels, charger power, and environmental factors. As Cadillac’s first luxury electric SUV, the Lyriq features a 102 kWh battery, making it an excellent choice for long-distance travel and daily commuting.

This calculator helps Cadillac Lyriq owners optimize charging efficiency, reduce energy costs, and extend battery lifespan with strategic charging plans.

How to Use the Cadillac Lyriq Charging Calculator

To determine your estimated charging time and cost, enter the following details:

1. Battery Capacity (kWh)

• Select the Cadillac Lyriq battery variant:
  • 102 kWh (All Models)
• The battery pack determines range and affects charging time.

2. Current Charge Level (%)

• Enter your battery’s current charge percentage.
• Example: If the charge level is 10%, enter 10.

3. Desired Charge Level (%)

• Enter the target charge level.
• Example: If charging from 10% to 90%, enter 90.

4. Charging Power (kW)

• Enter the charger power output:
  • Level 1 Charger (120V Home Outlet): 1.5-3 kW
  • Level 2 Charger (240V Home Charging Station): 11.5-19.2 kW
  • DC Fast Charger (Public Stations): Up to 190 kW
• The Cadillac Lyriq supports DC fast charging, significantly reducing charge times.

5. Temperature Condition

• Choose Normal, Cold, or Hot.
• Cold temperatures slow charging efficiency, while optimal conditions improve performance.

Additional Optional Settings

6. Battery Health (%)

• 100% represents a new battery.
• Over time, battery degradation may slightly reduce charging efficiency.

7. Electricity Cost ($/kWh)

• Enter your electricity rate per kWh.
• Helps estimate the total charging cost.

8. Time-of-Use Rate ($/kWh)

• If your utility provider offers off-peak electricity rates, enter the lower price.
• Charging during off-peak hours can significantly lower costs.

9. Battery Preconditioning

• If enabled, preconditioning warms up the battery before charging, improving efficiency in cold weather.

Once all values are entered, click Calculate to get your estimated charging time and cost.

How Charging Time Is Calculated

The calculator estimates charging time using the following formula:

Charging Time Formula:

\[ \text{Charging Time} = \frac{\text{Battery Capacity} \times (\text{Desired Charge Level} – \text{Current Charge Level})}{\text{Charging Power} \times \text{Charging Efficiency}} \]

Where:

• Battery Capacity = 102 kWh
• Desired and Current Charge Levels = Expressed as percentages
• Charging Power = Charger output in kW
• Charging Efficiency = Estimated power loss (~90%-95%)

Example Calculation:

• Battery Capacity: 102 kWh
• Current Charge Level: 10%
• Desired Charge Level: 90%
• Charging Power: 150 kW (DC Fast Charger)
• Charging Efficiency: 90%

\[ \text{Charging Time} = \frac{102 \times (90 – 10)}{150 \times 0.90} \] \[ \text{Charging Time} = \frac{102 \times 0.80}{135} \] \[ \text{Charging Time} = 0.6 \text{ hours} \]

Thus, it would take approximately 36 minutes to charge a Cadillac Lyriq from 10% to 90% using a 150 kW DC fast charger.

Tips for Efficient Charging

• Use DC fast chargers for quick top-ups on long trips.
• Charge during off-peak hours to lower electricity costs.
• Enable battery preconditioning in cold weather for faster charging.
• Avoid frequent deep discharges (charging from 0% to 100% too often can reduce battery lifespan).
• Monitor charging costs using energy plans with discounted EV rates.
