BYD "Seal 06DM-i" added to benchmarking report sales.

Ono Sokki Co., Ltd. (President: Yuji Okoshi), a manufacturer and distributor of electronic measuring instruments, will begin selling a new report, "Powertrain Performance/Hybrid Control Analysis," for the Chinese mid-size PHEV sedan "BYD Seal 06DM-i" as part of its new "Benchmarking Report Sales" business, starting March 26, 2026 (Thursday).

Since 2023, we have been selling "benchmarking reports" that measure electric vehicles. The "Powertrain Performance/Hybrid Control Analysis" report, which is being added to our lineup now, is a report that has been frequently requested by our customers. In the future, we plan to expand our report lineup for existing benchmarking vehicle models, and will also gradually add new vehicle models.

Key points of this presentation

• We have released a "Powertrain Performance/Hybrid Control Analysis" report to meet customer needs.
• We delve into the full details of BYD's PHEV system, "5th Generation DM Technology," which is attracting attention in the industry.
• We provide measurement data utilizing our engineering technology.

Target Market

• Automobile manufacturers and other companies involved in electric vehicles

Regarding the sale of benchmarking reports

In the increasingly sophisticated and diverse field of automotive development, benchmarking is a crucial source of information. Especially in xEV development, where speed is paramount, there is a strong need to quickly acquire information and utilize it in development. Furthermore, this information need is not limited to automotive manufacturers; it is required by a wide range of companies, including motor suppliers. Our company, committed to providing reports focused on electric vehicles, leverages our unique perspective as a manufacturer of measuring instruments.

BYD Sea Leopard 06DM-i New

Powertrain performance/hybrid control analysis

This vehicle is equipped with BYD's plug-in hybrid system, "5th Generation DM Technology," which combines a dedicated engine with a thermal efficiency of 46.06% with an electric motor and employs advanced coordinated control. In this report, we will explore the full scope of this PHEV Transient Bench, which is attracting attention in the industry, from two perspectives: "Powertrain Performance," which unravels the limits and efficiency of the vehicle's power performance, and "Hybrid Control Analysis," which deciphers the precise control according to driving scenarios, using our actual vehicle transient bench (RC-S) and other tools.

Report contents

Powertrain performance

• Output characteristics for each drive mode
  Torque and output characteristics of the drive shaft were measured for each drive mode.
• Driving force characteristics
  The characteristics of the drive shaft output in relation to the accelerator opening for each drive mode were measured.
• Power limiting characteristics due to temperature influence
  The system was operated at maximum output until the output limit was reached, and its behavior was measured.
• Output characteristics for each SOC
  The drive shaft output characteristics and the output characteristics of the motor, generator, and high-voltage battery were measured when the State of Charge (SOC) was changed.
• Power unit efficiency
  The vehicle's speed and load were varied, and the energy input to the vehicle and the output of the drive shaft were measured. Then, a power unit efficiency map was created using the rotational speed and torque of the traction motor as axes.

Hybrid control analysis

• Control characteristics during acceleration from a standstill
  We investigated the hybrid control behavior of the motor and engine when accelerating from a standstill to full throttle.
• Control characteristics during intermediate acceleration
  This study investigates the hybrid control behavior of the motor and engine when accelerating to full throttle from a constant speed driving state.
• Control characteristics during constant speed driving
  The hybrid control behavior of the motor and engine under constant speed driving conditions was investigated.
• Vehicle speed-torque characteristics in neutral
  We investigated the drive shaft torque at various vehicle speeds while in neutral, under different states of operation (SOC).
• Tip-out and regenerative characteristics
  We investigated the amount of regenerative power generated and the behavior of the mechanical brakes when the brake pedal is operated.
• Charge/discharge characteristics
  In addition to data on output limiting characteristics and regenerative characteristics, data on the inflection point of maximum charge/discharge power relative to the State of Charge (SOC) was acquired to investigate the charge/discharge characteristics.
• Mode driving
  We analyzed the hybrid control behavior of the motor and engine when driving in North American modes (UDDS, US06, HWY).
