Frequently Asked Questions
How do I calculate my EV's charging duration?
1. Energy Needed: (Target % - Current %) x Battery Size (kWh). 2. Time: Energy Needed / Charging Rate (kW). Example: 45kWh / 7kW = 6.4 hours. Use our tool to find the exact clock time it reaches the target.
Why does charging slow down after 80%?
To protect battery health, EVs taper the charging speed significantly once the battery reaches 80% State of Charge (SoC). This 'curtailing' helps prevent overheating and long-term degradation of the battery cells.
How can I time my charging for off-peak electric rates?
Use our Finish At mode. Enter the end of your off-peak window (e.g., 7:00 AM) and your estimated charging duration. The tool will tell you precisely when you should start the charge to finish just as rates go back up.
