Impedyme’s Combined HIL and PHIL (CHP) solution allows for the testing and validation of various EV powertrain components such as battery pack, inverter, electric motor in  early in the development, which can help EV manufacturers to reduce the risk of costly and time-consuming field failures and recalls, leading to more reliable and more efficient powertrain  and ultimately safer and better-performing EVs.

CHP plays a crucial role in the testing and validation of charging stations and battery packs for electric vehicles. CHP enables the emulation of realistic charge/discharge cycles by loading individual voltage-current (V-I) curves. This allows for the testing of the charging and discharging performance of the battery packs and thermal management system under various operating conditions, such as temperature, load, and aging.

 

• Impedyme’s CHP solution can improve the validation and performance of inverters in EV manufacturing through generating high-fidelity signals that emulate the behavior of the EV's powertrain. These signals can include voltage and current waveforms, thermal profiles, and communication protocols, among others. The inverter can then be tested in real-time, and its performance and response to different operating conditions can be analyzed and optimized and facilitate the process of identifying potential issues with the inverter's design, such as voltage or current spikes, thermal issues, or communication failures.

•  CHP enables manufacturers to perform comprehensive and realistic testing of the electric motor under various operating conditions and fault scenarios that are challenging to replicate in a real-world test. This approach helps manufacturers to identify potential issues with the motor's design and performance, such as torque ripple, noise, vibration, or overheating. In addition, Impedyme’s CHP solution facilitates the process of optimizing the performance of the motor, such as increasing the efficiency, reducing the weight, or improving the torque output.

• Impedyme’s Grid Simulator can be used to provide stable and clean voltages as well as generate worldwide grids. Impedyme’s highly flexible CHP could be used to emulate the electrical behavior of an EV both in AC or in DC for testing the output of a charger or an active charging cable. Imedyme’s CHP solution offers the highest degree of compatibility between HIL and PHIL and is currently the most cost-effective and versatile high-power PHIL test and emulation platforms on the market.
