UL2271 is suitable for light vehicle batteries, such vehicles include:
electric bicycle;
· Electric scooters and motorcycles;
• Electric wheelchairs;
• Golf carts;
· All-terrain vehicles;
non-manned industrial material handling equipment (electric forklifts);
· Cleaning vehicles and mowers;
· Personal mobile equipment (electric balance car).
UL2272 is suitable for personal mobile devices, such as: electric scooter, balance car.
Standard requirements:
lithium-ion cells shall meet the requirements of UL2580 or UL2271
battery: If the battery meets the requirements of UL2271, it can be exempted from testing: overcharge, short circuit, overdischarge and unbalanced charging tests.
From this, it can be seen that if lithium batteries are used in equipment applicable to UL2272, UL2271 tests are not required, but the batteries need to meet the requirements of UL2580 or UL2271. In addition, the requirements of batteries applicable to UL2271 vehicles for batteries are: lithium ion batteries need to meet the requirements of UL2580.
To sum up; As long as the battery core meets the requirements of UL2580, the UL2272 test can completely ignore the requirements of UL2271, that is, if the battery is only suitable for UL2272 equipment, it is not necessary to do UL 2271 certification.
Recommendations for certification
1, battery cell factory: used for electric balance car or scooter battery North American certification should be in accordance with UL2580 standard test certification;
2. Battery Factory: If the customer does not insist that the battery needs certification, he can not do it. When the customer has the request, according to the requirements of UL2271.
Recommendations for agency selection:
1. When the customer does not have an organization, the certification organization can be selected according to the comprehensive consideration of the certification cost and the customer's recognition degree; 2. When the customer has requirements, the certification organization shall be considered according to the customer's requirements, or the customer shall be persuaded to consider the certification organization according to the cost.
