In the core electronic control systems of new energy vehicles, automotive relays serve as critical components for current control, with their performance directly impacting the vehicle’s safety, reliability, and energy efficiency. As a technological pioneer in China’s new energy vehicle sector, Leapmotor has fully adopted Meishuo brand relays in its next-generation electronic control modules, leveraging their exceptional performance to safeguard the vehicle’s systems.
Meishuo Relays: The “Safety Guardian” of New Energy Vehicle Electronic Control Systems
As a leading brand in China’s relay industry, Meishuo boasts 20 years of deep industry expertise, with its products achieving world-class standards in core metrics such as contact reliability, electrical lifespan, and environmental adaptability. In Leapmotor’s electronic control systems, Meishuo relays perform several critical functions:
3.Rigorous Validation System:
All relay products applied in Leapmotor vehicles undergo a series of stringent tests:
– 1000-hour high-temperature and high-humidity test at 85°C/85%RH.
– Temperature shock cycling test from -40°C to 125°C.
The main application in this module is the MAA series of relays from MEISHUO, which usually adopts the standard 4-pin or 5-pin design and supports 12V and 24V power inputs, with excellent reliability and stability. It is widely used in automotive industry, such as window control, air conditioning, headlight and wiper control.
Amid the development wave of the “Four Modernizations” (electrification, intelligence, connectivity, and sustainability) in new energy vehicles, Meishuo relays have become the preferred partner for mainstream automakers, thanks to their outstanding technical capabilities and reliable quality. The successful collaboration with Leapmotor not only showcases the technological breakthroughs of domestically produced high-end relays but also sets a benchmark for the industry in achieving self-sufficiency and control over core components.
