New energy electronically controlled aging test, GripSeal quick sealing joint G70/G70R core solution

As the new energy vehicle market moves from "high-speed growth" to "high-quality development", vehicle safety, especially the reliability of the "three-power" system (battery, motor, electronic control), has become the core concern of consumers and manufacturers. In the assembly and decommissioning process of the electronic control system, aging testing is the last line of defense to simulate the real working conditions and verify the stability of the system. The improvement of its test efficiency and safety is driving the continuous innovation of production line connection technology.

The electronic control box, as the energy dispatching center connecting the battery and the motor, whether the complex cooling circulation system inside can operate without failure under high temperature and other aging testing environments directly determines the quality of the final product. At present, for the aging testing requirements of large-scale and fast-paced production lines, the modular scheme based on integrated detection trays has become the mainstream. In this scheme, the connection method between the tray and the coolant import and export of the electronic control components is no longer a simple physical connection, but has evolved into a key process point that affects the overall efficiency of the whole line.     

In the early days of production line practice, many manufacturers used a hose-fit clamp to connect the inlet and outlet ports. This method is not only time-consuming to install, but also unreliable sealing, which is prone to coolant leakage during long-term high temperature aging tests, resulting in the risk of electrical short circuits and production line contamination. With the improvement of testing standards, the industry has generally turned to quick-sealing joints. Such joints not only achieve a one-second connection, but also meet strict requirements in terms of flow, safety and life.

GripSeal G70The series of external card-type quick-sealing joints are designed to address the actual pain points of electronically controlled aging testing.

·Large flow path design:Ensure that the test medium (coolant) has no bottleneck effect during the circulation process, and truly restore the heat exchange state when the electronic control system is fully loaded to avoid distortion of test results due to limited viewership of joints.

·Self-locking structure:Automatic locking after connection can effectively resist the risk of accidental falling off due to pressure fluctuations or slight vibrations of the wire body during testing. This not only protects the safety of testers and equipment, but also eliminates the cost of repeated testing due to connection interruption.

·All stainless steel housing:For the corrosive environment of high temperature, high humidity and long-term contact with coolant in the aging room,G70sealing jointThe main body is made of stainless steel, which effectively guarantees the service life and sealing stability of the joint.

G70Series sealing jointThe core sealing element of the utility model adopts an end face sealing ring optimized for aging water inlet and outlet pipes. This design not only ensures the sealing effect, but also minimizes the barrier to the fluid section as much as possible, achieving both "reliable sealing" and "non-destructive flow", ensuring that the aging test results can truly reflect the heat dissipation performance of the electronic control system.

If the layout around the inlet and outlet of the electric control box is compact and the operating space is limited, GripSeal can be selectedG70RseriesLType quick sealing jointIt also has reliable sealing performance and durability.

From connection reliability to test accuracy, every improvement in the efficiency of electronically controlled aging testing requires continuous optimization of the detailed process.GripSeal has been deeply involved in the field of fast sealing connections for many years toG70、G70RAnd other series of sealing joint products are used as carriers to provide sealing solutions that can withstand production line verification for the testing of key components such as new energy vehicle electronic control and battery packs.Safer connections can achieve more secure electric travel. GripSeal will continue to focus on testing micro-innovations in sealing technology to help China's intelligent manufacturing run out of "acceleration".
