The European Standards Committee published a new version of the standard EN 15194:2017 A1:2023 for electric-assisted bicycles on August 23, 2023, and will be enforced from August 23, 2025. The battery test requirements of the new version of the standard have deleted the reference standard EN 62133-1, and the new version EN 50604-1 is the only judgment standard for the safety requirements of EPAC batteries. EN 50604-1 is a safety standard for secondary lithium batteries suitable for light electric vehicles (Light electric vehicle).
EN 50604-1 Scope of application
-
voltage class A (maximum working voltage ≤ 30Va.c(rms)/ ≤ 60Vd.c.) ;
-
A removable (including built-in) lithium-ion battery (pack) system for LEV with voltage class B (maximum voltage between 60Vd.c.- 200Vd.c.).
according to the standard requirements, the battery management system should be able to protect the battery system from damage, monitor and extend the service life, maintain the functional state, and be able to evaluate and control the cells, cell groups, and batteries, so that they can be specified by the cell manufacturer. Operation under conditions.
EN 50604-1 Test Items
-
mechanical Testing
-
environmental testing
simulation of vehicle accidents (squeezing, flooding, etc.)
electrical Testing
-
functional test (overcharge, overdischarge, deep discharge, etc.)
EN 50604-1 evaluates protection devices with different test options
Option 2: All protective devices have been assessed for functional safety at levels EN 61508 or ISO 13849 PLc.
-
Option 3: Perform FMEA analysis and then synchronize all single failure tests while processing electrical tests.
this means that EN 50604-1 has higher requirements for the safety design of batteries than EN 62133 series standards, so as to avoid potential fire, explosion, leakage and other dangerous accidents as much as possible.
