High performance, longer range, fast charging, and cost-effective design are the major objectives for Electric vehicle (EV) design and test engineer. An effective thermal management of the vehicle is the key to meet these objectives. 

Our faster and accurate fiber optic temperature sensors are ideal choice for testing high voltage EVs and helping design/test engineers to meet their objectives:

• Bring safety compliance to the test setup; Avoid thermal run-away issues
• Reduce test set-up time while covering for all test-conditions
• Increase pass rate with accurate performance assessment

Accurate thermal profiling and early detection of thermal run-away issues are very important in designing a high performance EV battery and avoiding product recalls. Better the temperature measurement more accurate and effective is the Battery Management System.

Rugged Monitoring’s Fiber Optic temperature sensors are being used by battery design/test engineers at each stage for battery testing: 

• Battery cell core and anode thermal profiling for fast charging
• Intercell temperature monitoring in Battery Modules
• Battery pack abuse testing and HV connectors temperature testing

Stator winding hot spot monitoring during the testing of EV motors is crucial as it helps in:

• Better insulation selection and cooling management
• Improving performance with better control algorithms
• Accurate performance rating and Age estimation models

Rugged Monitoring’s Fiber Optic temperature sensors are being used by major EV and motor manufacturers in their design, testing and vendor evaluation stage. These fast responsive and accurate sensors can directly be installed at stator windings and high voltage connectors without any isolation.

Measure accurately and manage effectively. Faster and accurate temperature measurement in EV inverter is a big challenge for inverter engineers due to their compact size, and high-power density. 

Rugged monitoring provides high dielectric, fast responsive, smaller size, and accurate temperature sensors for EV inverter testing. Our sensors are being used in inverter testing for:

• Direct and Accurate measurement of Junction Temperature (Tj)
• Capacitor Core temperature measurement without thermal run-away issues
• Cooling and HV connector thermal profiling

High voltage and Fast charging are the future of the Emobility. The key challenges that need to be addressed are how to make: 

• Safe charging plugs both from high voltage and temperature
• High performance on-board charger for fast charging

Rugged Monitoring’s fiber optic temperature sensors are faster, accurate and smaller to fit into charging plugs and compact on-board chargers. The high dielectric strength of our sensors makes them most suitable for Tj (Junction temperature) measurement in on-board Chargers and thermal profiling of charging pins in fast charging plugs.
