What Is the Polestar 2 Charging Calculator?
The Polestar 2 Charging Calculator is a tool designed to help electric vehicle (EV) owners estimate charging times and costs based on their battery capacity, current charge level, charging power, and external factors such as temperature and electricity pricing.
By using this calculator, Polestar 2 drivers can plan their charging sessions efficiently, reduce electricity costs, and extend battery lifespan by following optimal charging practices.
How to Use the Polestar 2 Charging Calculator
To estimate charging time and costs, enter the following details:
1. Battery Capacity (kWh)
- Select the battery size of your Polestar 2 model:
- Standard Range: 69 kWh
- Long Range (Single/Dual Motor): 75 kWh
- The battery size determines how much energy the car can store and affects charging duration.
2. Current Charge Level (%)
- Enter the battery’s current state of charge.
- Example: If the battery is at 1%, input 1.
3. Desired Charge Level (%)
- Specify the percentage you want the battery charged to.
- Example: If charging from 1% to 99%, enter 99.
4. Charging Power (kW)
- Input the charging station power output:
- AC Home Charger (Level 2): Typically 3 kW to 11 kW.
- DC Fast Charger (Level 3): Ranges from 50 kW to 150 kW+.
- Higher power chargers significantly reduce charging time.
5. Temperature Condition
- Choose from Normal, Cold, or Hot.
- Cold temperatures slow down charging and reduce battery efficiency.
Additional Optional Settings
6. Battery Health (%)
- A 100% rating represents a new battery.
- Over time, battery health may decline, affecting charging speed and capacity.
7. Electricity Cost ($/kWh)
- Enter your local electricity rate per kWh.
- This helps estimate total charging costs.
8. Time-of-Use Rate ($/kWh)
- If your electricity provider offers off-peak rates, enter the lower price.
- Charging during off-peak hours can save money.
9. Battery Preconditioning
- If enabled, preconditioning warms up the battery before charging, improving efficiency in cold weather.
After entering these values, click Calculate to determine your estimated charging time and cost.
How Charging Time Is Calculated
The calculator uses 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 = Selected based on Polestar 2 model (69 kWh or 75 kWh)
- Desired and Current Charge Levels are percentages
- Charging Power is in kW
- Charging Efficiency accounts for power loss (~90%-95%)
Example Calculation:
- Battery Capacity: 75 kWh (Long Range model)
- Current Charge Level: 1%
- Desired Charge Level: 99%
- Charging Power: 3 kW (Home charger)
- Charging Efficiency: 90%
Thus, it would take approximately 27 hours and 13 minutes to charge a Polestar 2 Long Range from 1% to 99% using a 3 kW home charger.
