Chroma has partnered with Altair, a global leader in computational intelligence, and Tron Energy to launch an advanced dynamic battery charge-discharge testing collaboration. This project aims to enable verification and enhancement of battery performance and lifespan through leading-edge equipment and precise simulation technology.
In the electric vehicle (EV) sector, our upgraded models now support charging current testing needs for 11kW bidirectional onboard charger (BOBC) systems, accommodating both 400V and 800V high-voltage platforms.
Chroma’s PowerPro 5 software, part of its comprehensive EV test system solution, features a Certificate Management Tool that allows users to load specific certificate files (*.p12, *.pem). Using designated OEM agreements and contract certificates, the software automatically performs public/private key encryption and decryption during the test to achieve the handshake and payment processes required for ISO 15118 PnC testing.
Chroma’s PowerPro 5 automated test software platform is now equipped with multi-threaded testing functionality and can simultaneously simulate up to four vehicles with identical or different communication protocols. Foothill Ranch,
Chroma 62180D-1200 Bidirectional DC Power Supplies support paralleling up to 30 units for an output power of 540kW and an output current of 1200A. This meets the requirements of today’s fuel cell engine assemblies, enabling the instruments to function as a highly efficient fuel cell simulator with energy recycling functionality.
Chroma’s compatibility and functional testing systems for EVSE have already been adopted by a great variety of domestic and foreign testing labs. Many EVSE manufacturers also use our solutions for end-of-line testing in their factories. Besides testing the charging process and safety mechanisms, one of the most important test items for multi-coupler EVSE products is power sharing (load management) testing.
62000D models offer power ratings of 6kW, 12kW, 18kW, 36kW, and 45kW with parallel and series operation capabilities and voltage ranges spanning from 0 to 100V/600V/1200V/1800V. With its four times auto-ranging operation range, the 62000D can cover a wide range of low voltage/high current and high voltage/low current scenarios for devices under test. This consolidation of multiple DC power supplies into a single 62000D unit brings space and cost savings when integrated into standard ATE systems or laboratories.
Integrated with any of our regenerative battery testers or bidirectional DC power supplies, our software simulates the battery state removing the wait time for the charge/discharge of an actual battery.
Though many countries have successively announced the timeframe to stop selling fuel vehicles, the electric vehicles of today still have some technical indicators remaining for improvement. The indicators such as
Car manufacturers are continuing to improve endurance in an effort to overcome EV range anxiety. As a result, the energy density of onboard batteries has gradually advanced. The next question
