BYD is expanding the use of its 240 kW peak-power electric motor, designated TZ200XYAT, across multiple mid-range electric vehicles. Recent regulatory filings confirm that the motor will be installed in the Seal 07 EV, Seal 06 GT, Seal 06 EV, Qin Max, Han EV, and Ti3, covering both the Dynasty and Ocean series. These filings provide technical specifications and dimensions while highlighting the 240 kW motor as the primary high-output option in this segment.
The TZ200XYAT is a permanent-magnet synchronous motor rated at 120 kW and capable of 240 kW peak output, approximately 326 horsepower. It is compatible with BYD’s 800V high-voltage architecture and supports the Megawatt Flash Charge system, enabling motor windings to participate in charging. Technical features include direct-cooling systems, ten-layer flat-wire stator windings, 0.2 mm-thick stator silicon steel sheets, lightweight eddy-current sensors, and variable-flux motors. BYD has also updated energy management and integrated electric control systems in mid-range EVs to complement this motor.
Vehicle filings show a range of applications. The Seal 07 EV includes the 240 kW motor and an optional roof-mounted LiDAR sensor, measuring 4995 mm long, 1910 mm wide, and 1495 mm tall. The Seal 06 GT is confirmed to use a rear-mounted TZ200XYAT motor with a peak output of 240 kW. The Seal 06 EV adds a larger body with a single-motor 240 kW variant alongside a 120 kW option.
The Qin Max EV features a 240 kW motor and measures 4866 mm long, 1880 mm wide, and 1495 mm tall. The Ti3 replaces the previous 170 kW and 200 kW peak rear motors with the TZ200XYAT, while retaining a 35 kW front asynchronous AC motor with 135 kW peak. The Han EV continues to use combinations of motors with rated outputs up to 300 kW and peak outputs up to 580 kW, with front motors in mid-range filings ranging from 150 kW to 200 kW.
BYD distinguishes the TZ200XYAT from other high-output units in its lineup, such as the TZ220XYAE and TZ220XYBS. These motors belong to the broader TZ220XY family. They are typically deployed as front motors in larger or performance-oriented dual-motor configurations, delivering higher system outputs and differing in tuning or packaging compared with the mid-range TZ200XYAT.
Vehicles equipped with the 240 kW motor fall into the mid-range price segment, between 100,000 and 150,000 yuan, or roughly 14,150–21,250 USD.
BYD’s TZ200XYAT motor integrates with advanced platforms, including e-Platform 3.0 Evo and the new 1000V “Super e-Platform,” which support megawatt charging. The motor is developed in-house and incorporates Silicon Carbide (SiC) technology, similar to other BYD high-output units. Its 240 kW output is suitable for mid-range passenger vehicles and can also be applied in larger vehicles, such as buses.
