Challenges
With the rapid growth of electric two- and three-wheelers worldwide, reliable EV charging and discharging connectors have become essential for safe and efficient power transfer. The Chogori Large 2+4 series has been a proven industry-standard battery connector for nearly a decade. As e-mobility evolves toward higher voltage, higher current, and longer range, the demand for high-performance connectors continues to rise. At the same time, batteries—being high-value assets—require enhanced protection, as water ingress can lead to performance issues and costly maintenance. This creates a growing need for connectors that provide waterproof protection even in an unmated condition.
In response, we developed the next-generation Large Pro 2+4 — a high-performance EV connector for electric two- and three-wheelers.
