Market Challenges
With the rapid development of electric two- and three-wheel vehicles, battery connection interfaces are facing evolving technical and regulatory requirements:
Global markets are introducing requirements for communication capability and waterproof performance (e.g., IPX7) at the battery system level, driving the transition from pure power transmission to more integrated interface solutions.
Frequent charging and battery swapping, combined with outdoor and harsh conditions, place higher demands on waterproofing, durability, and connection reliability.
Traditional connectors are primarily designed for power transmission and struggle to meet the combined needs of communication, safety, and reliability.
As early as around 2015, Chogori, in collaboration with a leading global drive system customer in the electric two-wheeler sector, pioneered the development of integrated power + signal connector solutions with the Large 2+1+5 series.
Through continuous validation and iteration ( Large pro ) in real-world applications, this solution has been widely adopted across the industry, driving battery interface design toward greater integration and higher reliability, and establishing itself as a mainstream technical approach.
Product Positioning
The Large 2+4 / 2+1+5 series is a mature and reliable connector solution designed for battery charging and discharging applications in electric two- and three-wheel vehicles.
The product supports up to 80V DC / 40A, features an IP67 protection rating, and offers a mating durability of up to 3,000 cycles. With its integrated power and signal design, it ensures stable and reliable connections under demanding operating conditions. It has been widely adopted across the industry and is recognized as one of the mainstream interface solutions.
