UL 4128 energy storage connector product use range:
theenergy storage connector consists of a cable connector, a cable, and a matching inlet for electrochemical cell applications.
Note:
1. The rated voltage of the energy storage connector is up to 2000Vdc or lower than 2000Vdc;
2. cannot be connected or disconnected under load;
3. not in dangerous places;
4. The cable used has an RTI temperature value of at least 90 degrees.
to do UL 4128, UL certification of energy storage connectors, what tests do you generally do?
Dielectric Voltage-Withstand, withstand voltage test, the test details are as follows:
Old Stress Relief, injection stress release test, test conditions are as follows:
put it in a 90-degree high-temperature oven for 7H, and then repeat the above pressure test.
Accelerated Aging Test - Rubber Compounds, for the seal ring, the test conditions are as follows:
put it in a 100-degree high-temperature oven for 70H, and then measure the hardness of the plastic. The change in the value before and after should be less than 10, and each color of plastic should be tested.
Temperature, temperature rise test, test conditions are as follows:
at normal temperature, or the ambient temperature declared by the customer, the product is connected to the maximum rated current, and the power cord with 90-degree RTI is connected to the load, working for 4 hours or reaching thermal stability, and the temperature rise of the electrical connection part cannot exceed 45K.
Strain-Relief Test, the test conditions are as follows:
first, the length of the power line shall be at least 305mm, and the tensile force of 156N shall be applied to the line tail for 1 minute, and the displacement shall not exceed 2mm.
Push Back relief Test, the test conditions are as follows:
first, the power cord is at least 305mm long, apply 26.7N thrust to the connection part for 1 minute, and the wire part cannot be pushed.
