Range extender
Avatr's Kunlun range extender system debuts in the 07, which consists of a battery and petrol engine electrically powering drive motors.
The initial battery option is a 39.05kWh CATL Freevoy hybrid-chemistry pack jointly developed by CATL and Avatr, and the 07 is the first vehicle to implement the new Freevoy-line of battery designs. It consists of both LFP and sodium-ion battery cells arranged in series, which allows for the sodium-ion cells to compensate for LFP cells' weaknesses in cold-weather performance and charge accuracy. As a result, CATL claims the battery can discharge at temperatures as low as -40. C, charge at -30. C, and performs like normal at -20. C, while having 40% higher battery state-of-charge accuracy.[12]
The engine is a JL469ZQ1 petrol 1.5-liter turbocharged four-cylinder unit supplied by Changan Auto, which has a peak output of 154 hp and is not mechanically connected to the wheels, instead powering an electric generator to charge the battery. It has an aluminium block and head and is equipped with direct injection and DOHC. It has a compression ratio of 15:1, allowing for peak thermal efficiency to reach 44.4% or 3.63kWh/L of petrol. It can operate at air temperatures from -35 to 65 C. Avatr claims that it produces less than 75dB of noise when operating due to NVH work done on the engine. To reduce vibration and noise by 90% at startup, the engine is placed at an optimal crank position at shutdown to reduce cylinder sound pressure by 62.5%.[13]
The rear wheels are powered by a 310. hp permanent magnet synchronous motor manufactured by Huawei. It features over 30 oil coolant spray nozzles in the motor windings, and a 50-temperature sensor array that allows the motor to safely run without thermal throttling closer to the permanent magnet's 140. C temperature limit, running at 132. C rather than 110. C like conventional motors. The single-speed gear reduction features 12 oil coolant spray nozzles.[13] All-wheel drive versions have a supplemental 176 hp AC induction motor powering the front wheels, also manufactured by Huawei.
The 39.05kWh battery has a charge rate of 3C, allowing for a 30–80% charge time of 15 minutes. Single-motor variants have an all-electric CLTC range rating of 245 km, and a total range of 1152 km. Dual-motor variants have an all-electric CLTC range rating of 245 km, and a total range of 1152 km. It has a peak discharge rate of 9C when at full charge, and a relatively high 7.7C while it is being charged by the petrol engine. This allows for a 0-100 km/h time of 4.9 seconds when fully charged, or 5.8 seconds while the engine is charging the battery, which is only a 15.5% increase compared to competitors who experience around a 45% increase in times.[13]
A variant with a larger 52.4kWh CATL Shenxing battery is expected to be released in 2025. It has a peak charge rate of 4C, allowing for a 30–80% charge time of 10 minutes. It has a CLTC all-electric range rating of 325 km, and a total range of 1220. km.[13]
Battery electric
The fully electric version of the 07 is equipped with a 82.16kWh CATL Shenxing LFP battery pack. It has a 4C peak charge rate and runs at 800V, allowing for a 0–80% charge time of 20 minutes.[14]
The rear wheels are powered by a permanent magnet synchronous motor manufactured by Deepal,[7] producing 338 hp and 365 Nm of torque. All-wheel drive versions have a supplemental AC induction motor manufactured by Chongqing Tsingshan Industrial powering the front wheels, outputting 252 hp and 280 Nm of torque.[7][14]
Single-motor variants have a CLTC range rating of 650. km, while dual-motor variants have 610. km.[14]
