SSCH180-4000/15000 New Energy Motor Dynamometer Test Bench
SSCH180-4000/15000 New Energy Motor Dynamometer Test Bench
Description
In the field of new energy commercial vehicles and high-end
passenger vehicles, 180-kilowatt motors are becoming the mainstream
configuration of drive systems. The performance of these high-power
motors directly affects the vehicle's range and heavy-load
capacity. The 180-kilowatt new energy motor dynamometer test bench
is precisely designed as a "performance testing ground" for this
type of motor, ensuring stable operation of high-power motors in
complex application scenarios through full-condition simulation and
precise data collection.
The dynamometer test bench is designed with a core power range of
180 kilowatts, which can simulate extreme conditions such as
commercial vehicle climbing (slope ≥30%) and passenger vehicle
high-speed cruising (speed > 160km/h), and also has the ability
to test bidirectional energy flow. When the motor is in the power
generation state (such as when the vehicle brakes downhill), the
test bench can feed the regenerated electricity back to the grid
with an energy recovery rate of over 95%, reducing the energy
consumption cost of the test and realistically recreating the
vehicle energy management scenario.

such as inter-turn short circuits of motors and sensor failures,
helping developers optimize fault-tolerant control strategies for
motors and improve the safety of on-board motor systems.
4. Intelligent data analysis platform
Built-in motor efficiency MAP generation tool, which can
automatically draw efficiency cloud maps for different speed -
torque intervals, supports benchmarking analysis with industry
benchmark motor data, and assists R&D teams in optimizing
design solutions.

Application Areas
1. Commercial vehicle drive motor testing
It is applicable to the performance verification of drive motors
for 8-12 meters pure electric buses and 4.5-18 tons logistics
vehicles, and can complete all tests such as rated power,
efficiency and overload capacity as stipulated in GB/T 18388-2021.
2. Research and development of high-end passenger car motors
Support motor system testing for four-wheel drive high-performance
electric vehicles (such as models that can accelerate from 0 to
100km/h in less than 3 seconds) and simulate motor thermal
management performance under conditions such as continuous rapid
acceleration and high-speed cruising.
3. Special vehicle power systems
Provide test solutions for low-speed high-torque motors of special
vehicles such as airport shuttle buses and port tractors, capable
of completing durability tests under heavy load conditions for more
than 10 hours.
4. Motor controller matching development
The parameter matching between the motor and the controller can be
optimized through the bench, such as optimizing vector control
parameters at 18000r/min high-speed conditions, which can increase
the motor efficiency in the high-speed zone by 3-5%, directly
enhancing the vehicle's high-speed range.
