Electromobility Solutions Powered by Battery and Motor Emulators

Impedyme’s CHP solution—combining Hardware-in-the-Loop (HIL) and Power-Hardware-in-the-Loop (PHIL)—enables early-stage testing of EV components like battery packs, inverters, and electric motors. This helps manufacturers reduce costly field failures and ensure a more reliable, efficient, and safer powertrain system.

CHP plays a crucial role in battery emulator testing and validation of EV battery packs and charging systems. It can emulate realistic charge/discharge cycles using individual voltage-current (V-I) profiles, allowing engineers to assess performance under various thermal and load conditions. 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.

To optimize EV inverter design, CHP can generate high-fidelity voltage and current signals that simulate real driving conditions. These signals can be used to validate thermal performance, communication protocols, and electrical response 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 empowers manufacturers to conduct in-depth EV drive system validation by simulating fault conditions, torque ripple, noise, and temperature variations—conditions that are otherwise hard to recreate in real-world tests. 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.
CHP can emulate AC/DC power flow for both charger and active charging cable validation, ensuring compatibility with global grid profiles. 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.
