Key Points for Energy Storage Connector Selection

I. Core Count Selection: Based on Transmission Requirements

1. Single-Core Connector

◦ Features: 1 terminal, simple structure, low cost

◦ Application: Simple single-circuit transmission such as battery cell series/parallel connection, small inverter single circuit

◦ Reminder: Verify rated current/voltage compatibility

1. Dual-Core Connector

◦ Features: 2 independent terminals, simultaneous dual-circuit transmission, simplified wiring

◦ Application: BMS "power + signal" parallel transmission, dual-output connection

◦ Reminder: Parameters of the two terminals must match their respective circuits

1. Tri-Core Connector

◦ Features: 3 terminals, supports multi-circuit/three-phase power, high integration

◦ Application: Industrial/commercial energy storage main circuits, complex systems requiring grounding

◦ Reminder: Prioritize UL/IEC certified products; ensure insulation and temperature resistance meet standards

II. Connector Type: Based on Space Conditions

1. Straight Connector

◦ Advantages: Easy plug-in, low signal loss, low cost

◦ Application: Scenarios with sufficient equipment spacing (e.g., outdoor power station open wiring, equipment front docking)

◦ Note: Narrow spaces may cause cable bending damage

1. Angled Connector (mostly 90°)

◦ Advantages: Fits equipment wiring, saves space, avoids cable extrusion

◦ Application: Compact spaces (e.g., energy storage containers, wall-mounted energy storage cabinets)

◦ Note: Align the angle during plug-in; prevent loosening from pulling

III. 3-Step Quick Selection Method

1. Determine core count: Single circuit → Single-core; Dual circuit → Dual-core; High-power/complex circuit → Tri-core

2. Choose type: Sufficient space → Straight; Compact space → Angled

3. Verify parameters: Current, voltage, temperature resistance (-40℃~125℃), protection level (IP67+ preferred)
