Test Facilities
Test Facilities at CamMotive
Our E-testing facilities include chassis dynamometers, a 4WD hub dyno system, battery cell and module test systems and dynamometers for e-motor testing. The test cells are fitted with equipment and instrumentation for electric powertrain testing, including battery emulation and electrical power analysers. All of our highly-qualified engineers are directly involved in operation of the test facilities, promoting a hands-on and productive approach to solving technical challenges. Extensive in-house development of test system hardware and software means that we are able to offer an innovative, flexible approach which is essential for meeting new challenges.
4WD Hub Dyno
A 4WD hub dyno system is available. The system is equipped with 4 high-performance permanent magnet dynos with 240 kW of absorption capacity per wheel. This facility is a flexible test cell, capable of running full vehicles or transaxle arrangements and is equipped with a 500 kW battery emulator.
Chassis Dynamometer
CamMotive’s 2WD and 4WD chassis dynamometers are equipped with robot drivers to provide the highest throughput and repeatability.
When combined with extensive instrumentation options, these facilities are an ideal platform for calibration development, hardware assessment or vehicle benchmarking. The chassis dynamometers are equipped with charging infrastructure to support electric vehicle testing.
Battery Cell Testing
CamMotive has over 800 channels of cell testing capability which can be configured to deliver up to 800 A. Tests can be performed in several dynamic climatic chambers, allowing operation from -40°C to +180°C. Process thermostats are available for testing systems with liquid temperature control systems. Specialist swelling equipment is available for dynamically measuring cell changes in-use and as they age. Additionally, the experts at CamMotive can help with EIS analysis, cell modelling and calibration.
Battery Pack Testing
We have several bi-directional systems to support module and pack testing under controlled environmental conditions. For large packs we have up to 1 MW (1000 V, 1000 A). Our fastest supplies allow step changes to be applied in less than 20 µs. Tests can be run under a range of conditions, including simulation of duty cycles measured from vehicle tests. To support battery testing, CamMotive has developed its own Battery Management System (BMS) for the test environment to control and protect the battery during the test process.
Hydrogen Systems
Our hydrogen fuel cell test facility is capable of up to 150 kW (with potential for 200+ kW systems). The test cell has climatic ambient control down to -20°C and equipped with a flexible power source/sink, a hydrogen supply that includes a Coriolis flow meter for accurate fuel measurement and twin circuit cooling capability is available to control separate low and high temperature loops. Dedicated precision measurement equipment, including H2 mass spectrometry, is available to ensure accurate measurements under a range of conditions.
For hydrogen ICE applications, our combustion group at Cambustion can provide support.
E-Motor Dynamometer
CamMotive has test cells equipped for E-motor testing. These cells include temperature control and coolant and oil conditioning. Tests can be run down to -20°C.
