BS EN 62660 is a series of European standards on secondary lithium-ion cells for the propulsion of electric road vehicles that discusses the best procedures and specifications required for increasing the safety of lithium-ion cells. BS EN 62660-3 is the third part of a series of documents on lithium-ion cells. BS EN 62660-3 specifies test procedures and the acceptance criteria for the safety performance of secondary lithium-ion cells and cell blocks used for the propulsion of electric vehicles (EV) including battery electric vehicles (BEV) and hybrid electric vehicles (HEV). BS EN 62660-3 intends to determine the basic safety performance of cells used in a battery pack and system under intended use, and reasonably foreseeable misuse or the incident, during the normal operation of the EV. The safety requirements of the cell in BS EN 62660-3 are based on the premise that the cells are properly used in a battery pack and the system within the limits for voltage, current, and temperature as specified by the cell] manufacturer (cell operating region). The evaluation of the safety of cells during transport and storage is not covered by BS EN 62660-3.
NOTE 1: Cell blocks can be used as an alternative to cells according to the agreement between the manufacturer and the customer.
NOTE 2: Concerning the cell for plug-in hybrid electric vehicle (PHEV), the manufacturer can select either the test condition of the BEV application or the HEV application.
NOTE 3: The safety performance requirements for lithium-ion battery packs and systems are defined in ISO 12405-3. The specifications and safety requirements for lithium-ion battery packs and systems of electrically-propelled mopeds and motorcycles are defined in ISO 18243 (under development). IEC 62619 (under development) covers the safety requirements for the lithium-ion cells and batteries for industrial applications including forklift trucks, golf carts, and automated guided vehicles.
NOTE 4: Information on the cell operating region is provided in Annex A.
BS EN 62660-3 provide guidance on lithium-ion cells for the propulsion of electric road vehicles:
Electric road vehicles (EV) including hybrid and plug-in hybrid electric vehicles are beginning to diffuse in the global market with backing from global concerns on CO2 reduction and energy, recent advances in technology, and cost reduction. This has led to a rapidly increasing demand for high-power and high-energy-density traction batteries represented by lithium-ion batteries.
BS EN 62660-3 provides guidance on test conditions, electrical measurement, safety tests, mechanical, electrical, and thermal tests.
BS EN 62660-3 specify the safety criteria at the cell level, in order to secure the basic safety level of cells which differ in performance and design, and are applied to a variety of types of packs and systems. For automobile applications, it is important to note the design diversity of automobile battery packs and systems and specific requirements for cells and batteries corresponding to each of such designs. Based on these facts, BS EN 62660-3 provides a basic level of safety test methodology and criteria with general versatility, which serves a function in common primary testing of lithium-ion cells to be used in a variety of battery systems.
