As the global new energy vehicle industry booms, the Indian market, an emerging blue ocean, has raised increasingly stringent quality requirements for EV charging infrastructure.

Recently, Shenzhen VILVA has successfully customized an EV charging gun insertion-withdrawal life & temperature rise aging test equipment for an Indian client, and the unit has been delivered smoothly. VILVA also supplies high-performance load bank, resistive load bank and EV load bank for various electrical reliability testing projects.

### What Testing Challenges Are Faced

1. Low efficiency and large deviation in manual testing: Manual plug-in & pull-out operation cannot maintain a constant speed (standard requirement: 0.8±0.1 m/s), and it fails to carry out tens of thousands of fatigue tests.

2. Separated test items: Life test, temperature rise test and resistance test usually require separate machines including independent load bank units. It brings high equipment cost and repeated fixture installation, which harms test accuracy.

3. High safety risks: During high-current (≤250A) and long-time aging testing, electric leakage or short circuit may trigger safety accidents. Operators cannot detect sample damage instantly.

###Five Test Modes for Multi-function All-in-one Machine

1. Insertion & withdrawal test mode

2. Temperature rise test mode

3. Insertion & withdrawal + temperature rise combined test mode

4. Insertion & withdrawal + resistance test mode

5. Insertion & withdrawal + temperature rise + resistance test mode (Full integrated mode) This all-in-one tester works together with load bank to complete comprehensive EV charging component validation.

###Complete Hardware Configuration & Safety Protection

1. High-rigidity structure and highly compatible fixture

2. Precise servo drive and transmission system Driven by servo motor and ball screw, guided by silent sliding rails, the fixture performs reciprocating movement, providing maximum 300N insertion & withdrawal force. Our load bank adopts similar robust mechanical design for long-hour continuous testing.

###Six Intelligent Safety Protection Systems

Alarm detection: Follow the principle of "conduct when it should be connected, cut off when fault occurs". The system judges sample damage via logic of position and current, triggers sound-light alarm and stops automatically once abnormal.
Earth leakage protection: Earth leakage switch installed at the incoming terminal to cut off control power instantly when leakage occurs.
Over-current protection: Current upper limit configurable to prevent overcurrent or short circuit, same safety logic applied to our resistive load bank.
Overload protection: Built-in circuit breaker for automatic tripping under overload status.
Door interlock protection: Safety switches fitted on all movable cabinet doors. Power cuts off automatically once the cabinet opens to avoid electric shock.
Emergency stop switch: Emergency stop button on panel for one-click power cut in emergency. Wire protection grommets equipped on inlet & outlet ports to prevent cable damage.

To address the Indian customer’s testing pain points of low efficiency, scattered test items and high safety hazards in EV charging gun inspection, VILVA delivers a perfect solution with this non-standard customized test equipment. Besides charging connector testers, VILVA also provides custom load bank solutions for generator, UPS and EVSE performance testing.
