Range, battery capacity and charging: what the numbers mean
Battery energy is measured in kWh; charging power is measured in kW. The catalog battery figure is an estimate and may not distinguish gross from usable capacity. EPA energy consumption includes charging losses, so multiplying it by range does not establish pack capacity.
Charging speed changes with battery temperature, state of charge, charger capacity and vehicle limits. A peak kW figure does not apply throughout a charging session.

BYD Seal U FAQ
What is the range of the 2025 BYD Seal U Design?
The 2025 BYD Seal U Design has an EPA-rated range of 310 miles (500 km) on a full charge. Real-world range varies based on temperature, speed, terrain, and HVAC usage.
How long does it take to charge the 2025 BYD Seal U Design?
The 2025 BYD Seal U Design supports DC fast charging at up to 120 kW, reaching 80% in approximately 33 minutes. On a Level 2 (240V) home charger, a full charge takes approximately 9 hours.
How does cold weather affect the 2025 BYD Seal U Design's range?
Cold weather can reduce range through battery conditioning and cabin heating. The table on this page shows a simplified calculated scenario, not a measured result for the 2025 BYD Seal U Design. Use the range calculator to compare assumptions and follow the vehicle manual for preconditioning.
What is the battery size of the 2025 BYD Seal U Design?
Our catalog lists 71.8 kWh. This is a catalog estimate, not a verified usable-capacity figure for every battery variant. kWh measures energy; kW measures charging power. EPA wall-energy consumption includes charging losses and cannot be used to infer exact pack capacity.
How much does the 2025 BYD Seal U Design cost?
The 2025 BYD Seal U Design has a historical catalog MSRP of $42,500. This is not a current offer. Check the seller for current vehicle condition, configuration, price and local incentives.
What connector type does the 2025 BYD Seal U Design use?
The 2025 BYD Seal U Design uses a CCS connector. CCS is the most widely supported DC fast charging standard in the US.
