Global Demand for E-bike Connectors Is Booming

Due to the severe global environmental pollution situation, bicycle travel is more environmentally friendly and healthy. This is also boosting the demand and development of e-bike connectors. Connector developers are helping e-bike designers to develop the next generation of pedelecs that are lighter, stronger and more reliable.

JST SM Connectors

A wide variety of connectors are involved in the operation and charging of e-bikes and pedelecs. The main ones include JST balance connectors to support the battery management system, QR connectors to connect the battery to the bike, as well as easy-to-use functional and magnetic contacts, SM connectors for small signal lines, moisture-resistant XT 90 connectors, bullet connectors, and power connectors for current-carrying applications.

Design implications

As the market has evolved, so has the design of e-bikes. People who commute to work every day want lightweight bikes so they can be easily carried around public places. They also appreciate the variety of data they see on the digital display, including data from the front and rear lights, as well as speed, distance and heart rate measured by sensors.

The use of many sensors, motors, batteries, etc. in an e-bike requires more cables and connectors, but at the same time cannot increase the size and weight of the bike.

Connector selection

There are several factors that influence the choice of connectors for e-bikes.

Data and power from the battery to the motor is the main concern. Larger wires and cables are needed to handle the current, but for data transfer, customers don't want to be visible. They want connectors that are compact, waterproof, easy to assemble and easy to identify.

Cables and connectors are usually integrated into the frame of the bike, so they have to be very small. We have to consider more or less the limits of the physical characteristics of the current and size combination.

It is also important that the connectors are waterproof because the bicycle frame components are exposed. Even if they are located inside the frame, the connectors can still come into contact with water during flushing or other cleaning processes.

In addition, the connectors must be safe and reliable and not be affected by vibration, etc., during use for transport cleaning.

Current requirements

Another recent development in electric vehicle design is the future use of motor and battery connectors current handling capacity increases, from 10 to 15A typical demand swells to 40 to 60A. To keep up with higher power requirements, designers are using larger connectors, typically in the 20mm diameter range, capable of handling 40 to 45A of current from the motor to the battery.

The rapid growth of electric vehicles is driving innovation in connector products for this unique market. Due to the severe global environmental pollution situation, bicycle travel is more environmentally friendly and healthy. This is also boosting the demand and development of e-bike connectors.

According to industry experts, the application area is also expanding, in the field of scooters, electric motorcycles and other new energy products will lead the innovation and development of connector products. GRAND specialized in integrates research and development, production and sales, and its products are used in professional fields such as new energy vehicles, solar energy, aviation, aerospace, medical care, nuclear technology, and military applications.
