Performance

The BYD Dolphin 44.9kWh Boost offers modest performance with a maximum power of 130 kW (177 hp / 174 bhp) and a total torque of 260 Nm (192 lb-ft). It accelerates from 0 to 100 km/h (0 to 62 mph) in 7 seconds and has a top speed of 160 km/h (99 mph), aligning more closely with traditional internal combustion engine vehicles.

Battery, Range, and Charging

The high-capacity battery has a gross capacity of 46.0 kWh and a net usable capacity of 44.9 kWh, providing a 1.1 kWh buffer (2.4%) for battery protection. With a nominal voltage of 333 volts, the system is classified as a 400-volt battery system, aligning with industry standards. The Lithium-Ion battery utilizes LFP technology, offering both benefits and drawbacks compared to typical NCA/NMC batteries.

According to the WLTP (Worldwide Harmonized Light Vehicles Test Procedure) standard, the vehicle’s range is 315 km (196 miles), with an energy consumption rate of 14.3 kWh/100 km (3 mi/kWh). For more details about the range, see real-world data and range listings on this model’s range and consumption page.

The vehicle supports fast DC charging with a maximum power of 65 kW. Charging from 0% to 100% takes approximately 66 minutes, while a more typical scenario from 10% to 80% takes 38 minutes with an average charging speed of 49 kW. Considering an additional 5 minutes for each charging stop due to driving interruptions, the optimal charging range is from 1% to 43%. This results in an effective charging speed, including time lost, of 46 kW, with each charging session taking about 24 minutes and 21 seconds.

In a 1000 km challenge at a constant speed of 120 km/h (75 mph) with an assumed consumption rate of 22 kWh/100 km, the trip would take about 12 hours and 7 minutes, requiring ten charging stops from 3% to 42%, totaling 228 minutes of charging time.
