Parent Product
Temperature Control Units For EV Electric Vehicle Testing

The OBC Inverter Test Cooling System is designed for the comprehensive testing of the onboard charger (OBC) and DC-DC converter (DCDC), which are integral components of electric vehicles (EV). Ensuring the optimal functioning of these core elements is vital for the overall performance and safety of the entire vehicle.

This system facilitates the development and testing process, allowing for a thorough examination of the functions and performance of both the OBC and DCDC components, contributing to the reliability and efficiency of EV.

OBC Inverter Test Cooling System by Qualitest

The OBC (onboard charger) and DCDC (DC-DC converter) are pivotal elements in electric vehicles (EV), with the operational excellence of DCDC and OBC being crucial for the overall performance and safety of the entire vehicle. In the course of developing and testing OBC and DCDC, as well as the entire vehicle, a thorough examination of the functions and performance of OBC and DCDC is necessary.

Closed circulation
system		The whole system is a fully enclosed system. There is no oil mist at high temperature, and low temperature does not absorb moisture in the air. The system does not increase the pressure due to high temperature during operation, and the heat medium is automatically replenished at low temperature.
