Battery Connectors for Transportation Applications

Amphenol ICC custom battery connectorAmphenol ICC offers reliable and robust custom IP67/IP68 connector solutions for e-bikes and swappable battery stations. The Dual Beam contact design for receptacle contacts aids in establishing a reliable electric connection. These customized battery/charger connectors meet industry standards and are available in various pin configuration and connector sizes. With a current of 40A, these connectors are highly durable and support up to 4,000 mating cycles.


Greenconn series GZZD201 low profile BMS connectorThe series GZZD201 Low Profile BMS Connector from Greenconn offers reliable, compact solutions for automotive infotainment system needs. This low-profile board-to-board connector is an ideal option for the limited installation space found in automotive infotainment systems and ECUs. The side-plug surface-mount type BMS connector provides numerous features that ensure its integrity and endurance. Metal sheets on both sides create a strong, reinforced connection when employing solder-mount technology. A locking mechanism located on the outside of the housing ensures the reliability of the contacts after mating, while its foolproof design found inside the housing helps to avoid mis-mating. Furthermore, its box-type housing prevents the deformation of the contacts from collision.

Smiths Interconnect’s spring probe contactsSmiths Interconnect’s spring probe contacts provide reliable electro-mechanical performance through hundreds of thousands of cycles. They are available in a variety of sizes, spring forces, and terminations. Smiths Interconnect’s compression-mount connectors utilize spring-probe technology, which offers tremendous advantages in reliability, performance, and efficiency in comparison to conventional technologies like stamped metal, wire mesh, pin-and-socket, or elastomer.


Hirose Electric’s low-profile wire-to-board ZE05 Series connector Hirose Electric’s low-profile wire-to-board ZE05 Series connector is designed for high heat and high vibration applications including automotive, off-highway, and transportation. Combining a space-saving design with high heat resistance up to 125 °C, the 2 mm pitch ZE05 Series connector maintains high electrical conductivity even in severe heat environments. A double spring, three-point contact design with minimal clearance ensures a consistent, highly reliable connection in high vibration conditions. Rated to 5A @250 VAC, the mono-pole power connector is designed for a wide range of applications including automotive converter, inverter, battery, on-board charger, ECU and more. Utilizing cost-effective tin-plating, the ZE05 Series connectors provide stable contact resistance for up to 3,000 cycles. A contact retainer prevents incomplete connection and offers a pull force of 40N. The ZE05 Series operates in environments from -40 °C up to 125 °C, has a rated voltage of 250V AC, and is available in several variations including straight and right angle for design flexibility.

MX77 Series from JAEThe MX77 Series from JAE excels in miniaturization, low-profile, and terminal retention strength for in-vehicle applications. The compact MX77 Series has a measured terminal retention force of 50N and uses 0.4 mm size contact terminals, a reduction of up to 37% compared to JAE’s 0.64 mm contact terminal. The MX77 Series in BMS are used to monitor voltage, therefore it is important to have reduced temperature rise. Temperature increases also affect the life of the battery and are very important since optimal performance must be achieved to extend battery life. The high heat-dissipating material for the pin terminals, which has been found to be an area of greater temperature rise when compared to socket terminals, helps reduce temperature rise under the same current-carrying conditions as the widely used 0.64 mm tab size for MX34.

APP’s two-pole SB connectors from Allied ElectronicsAPP’s two-pole SB connectors from Allied Electronics & Automation are based off the design pioneered by Anderson in 1953 and set the standard for DC power distribution and battery connections. SB 50 connectors feature a rugged one-piece plastic housing and use stainless steel springs to hold low-resistance contacts in place. Wires sizes from #16 (1.5 mm2) to #6 (13.3 mm2) are held in the smallest of the SB series housings.

KYOCERA AVX Single IDC Contact and Cap ConnectorsKYOCERA AVX Single IDC Contact and Cap Connectors, offered through Mouser, are designed to support larger wire gauges from the perspectives of robustness and current rating. The 9177-500 series offers 18AWG to 12AWG wire gauge handling capability and 1.9 mm, 2.2 mm, 2.6 mm, and 3.1 mm diameter measurements depending on the model. KYOCERA AVX Single IDC Contact and Cap Connectors are ideal for industrial motor controls, outdoor/transportation lighting, and solar and alternative energy applications.


The HPC high-voltage connector from iConnectorThe HPC high-voltage connector from iConnector can be used in electric vehicles, battery applications, and energy storage. The IP68-rated connector features 1000V and up to 500A DC current.
