"Thermal-VRS Transient Bench"
The T-VRS is a testing device that can evaluate the thermal management system of electric vehicles. By using this testing device, it is possible to simulate a vehicle for the components used in thermal management. This allows the development of thermal management to utilize a pre-development environment that merges real machines and virtual models, contributing to faster and more efficient development, as well as shortening development time and optimizing energy efficiency.
Background of Collaboration
In traditional automotive development centered around internal combustion engines, testing of powertrains and HVAC (the core components of automotive air conditioning systems) was conducted on a component-by-component basis. In contrast, with the rise of electric vehicle development, we have developed testing equipment that leverages the strengths of two companies to conduct comprehensive vehicle testing.
The points of this presentation
- Chino Corporation and Ono Sokki Co., Ltd. jointly develop thermal management test equipment for electric mobility.
- Testing is possible by simulating real vehicle environments in components related to thermal management.
target market
- Automobile manufacturers and various companies related to electric vehicles.
Thermal Transient Bench
In the development of electric vehicles, significant effort is required to improve the overall thermal performance of the vehicle (the ability to efficiently dissipate heat and maintain an appropriate operating temperature). To enhance development efficiency and shorten the time to release electric vehicles, this is achieved by replacing traditional methods with simulations in a virtual environment using dedicated software (model-based development). However, it would be even more effective if test benches that can be implemented simultaneously with powertrain development are available. Furthermore, through evaluations aimed at "energy saving," "safety," "longevity," and "comfort," we contribute with technologies that can optimally control and utilize "heat."
Ono Sokki We have expertise in developing realistic simulation models that require predictive values and empirical formulas, as well as in powertrain bench testing in general.
Meanwhile, Chino not only excels in technologies for temperature “measurement,” “control,” and “monitoring,” as well as ensuring reliability through “calibration,” but also possesses many years of expertise in “automotive air conditioning system test equipment and environmental test chambers,” contributing to the implementation of simulation model technologies for Ono Sokki.
The "Thermal-VRS Transient Bench" enables thermal management testing without a physical vehicle, thanks to the fusion of know-how from Chino and Ono Sokki. In the future, we plan to start selling this test bench and install it at Ono Sokki's development and manufacturing base, the Utsunomiya Technical & Product Center, to carry out the development of test benches that anticipate the evolution of mobility.
Sales start date: end of 2026

The 'Thermal Transient Bench' is a system that integrates Ono Sokki Co., Ltd.'s simulation technology for thermal management in automotive powertrain evaluation systems with Chino's technology for automotive air conditioning system test equipment and environmental test chambers. By enabling evaluation that reproduces actual machine conditions without the need for an actual vehicle, it leads to accelerated MBD and improved quality. Through the realization of this 'Thermal Transient Bench,' both companies aim to expand the market share of Japanese electric vehicle development and strive to bring us closer to carbon neutrality.
Ono Sokki Co., Ltd. President and Representative Director Yuji Okoshi
We have recently co-developed an automotive thermal management evaluation system that integrates the temperature measurement and control technologies of CHINO Corporation with the multi-physical quantity measurement and analysis technologies of Ono Sokki Co., Ltd. By using this system, it is possible to simultaneously visualize complex phenomena including temperature and energy, enabling the integration of evaluation processes that were previously fragmented. This allows for a correct understanding of phenomena from the early stages of development and empowers developers to advance their decision-making. This testing equipment aims to solve the carbon neutrality challenges faced by the automotive industry.
About Chino
Founded in 1913 and established in 1936, the company will celebrate its 90th anniversary in 2026. Its core business involves the manufacturing and sales of products that can measure, control, and monitor temperatures ranging from extreme low (-269°C) to ultra-high (3500°C). Additionally, it undertakes instrumentation projects that combine measurement, control, and monitoring, as well as calibration services for measuring instruments. At Chino, achieving the 'big goals' that customers aim for beyond measurement, control, and monitoring is referred to as 'Loop Solution'. Centered around temperature, the 'Loop Solution' constantly aims to realize a sustainable society across a wide range of industries.
