BYD Original PLUS (Japanese name: ATTO3)

We used a hub dynamometer to measure the output characteristics for each drive mode and the maximum output for each State of Charge (SOC). We also obtained an efficiency map of the power unit (drive shaft output / battery power).

Using a hub dynamo, we investigated the behavior of the vehicle until power limiting was applied when maintaining the maximum power output or maximum vehicle speed.

Using a hub dynamometer, we measured the drive shaft output characteristics in response to accelerator pedal opening for each drive mode. We also measured the deceleration characteristics when tipping out, as well as the deceleration and regenerative power for each State of Charge (SOC), including a full charge. Furthermore, we investigated the regenerative characteristics (regenerative power and mechanical brake behavior) when the brake pedal was operated.

In accordance with GTR No.15 Amendment 6, we calculated the driving resistance from the coasting time measured on the test course. This data can be used as load data for performing mode-based energy consumption and real-world driving simulations on a test bench.

Based on JIS D 4234, we measured the rolling resistance and rolling resistance coefficient of the original equipment tires.

To investigate the vibration of the motor and inverter during steady-state and transient operation in the low-to-high speed range, a 3-axis accelerometer was installed, and measurements and analyses were performed.

1/2-inch microphones were installed on each of the six sides of the power unit, including the motor and inverter, and measurements and analyses were performed during steady-state and transient operation in the low-speed to high-speed range.

To investigate the vibrations transmitted from the power unit to the vehicle body, we used a 3-axis accelerometer to measure and analyze vibrations on both the unit and body sides of the power unit mount.

1/2-inch microphones were installed in the driver's and passenger's seats inside the vehicle, and noise levels were measured and analyzed during steady and transient driving at low to high speeds.

We measured and analyzed the vibrations of the steering column and the driver's seat when driving on a harsh road surface.

To investigate vibrations transmitted from the tires while driving, we measured and analyzed vibrations from the steering knuckle and suspension towers, among other components.

This vehicle uses a heat pump to manage battery temperature and provide cabin air conditioning. The vehicle is driven under varying ambient temperature, driving conditions, and air conditioning settings, and the temperature changes in various parts and the behavior of the refrigerant control valve are measured together.

Ono Sokki Co., Ltd. (hereinafter referred to as "the Company") will deliver the results of measurements taken using its own proprietary methods on commercially available vehicles, as well as secondary products such as test reports created based on those measurement results. (Hereinafter referred to as "delivered products.")
Delivered products will be provided as electronic data. Delivery will be via a cloud server or on physical media (DVD/Blu-ray disc). Depending on the type of product, the data volume may be enormous, in which case delivery will be via a cloud server or on high-capacity media such as Blu-ray discs. If any defects or errors are found in the delivered products within one year of delivery, a corrected version will be provided free of charge.
