BS EN 61982-4 is a part of the BS EN 61982 series of international standards that discusses Secondary batteries (except lithium) for the propulsion of electric road vehicles.
BS EN 61982-4 specifies test procedures and acceptance criteria for the safety performance of nickel-metal hydride (Ni-MH) secondary cells and modules used for the propulsion of electric vehicles (EV) including battery electric vehicles (BEV) and hybrid electric vehicles (HEV).
BS EN 61982-4 intends to secure the basic safety performance of the cell as used in a battery system under intended use and reasonably foreseeable misuse, during the normal operation of EV. The safety requirements of the cell in this standard are based on the premise that the cells and modules are properly used in a battery pack and system within the limit of voltage, current and temperature as specified by the cell manufacturer.
Note: The evaluation of the safety of batteries during transport and storage is not covered by BS EN 61982-4.
BS EN 61982-4 on secondary batteries is applicable to:
Nickel–Metal Hydride Battery. NiMH batteries have higher power and energy density and a much longer life cycle compared to lead-acid batteries. They are also completely safe and their power output is not affected by the battery state of charge. A module is a group of cells connected in a series and/or parallel configuration with or without protective devices, e.g., fuse or positive temperature coefficient (PTC), not yet fitted with its final housing, terminal arrangement and electronic control device.
BS EN 61982-4 provides you with the guidance for the electric road vehicles (EV) including hybrid electric vehicles (HEV) begin to diffuse in the global market with backing from global concerns on CO2 reduction and clean energy, as well as from relevant technology advancement and cost reduction. Nickel-metal hydride (Ni-MH) batteries have advantages in cost and balanced performance and have been used extensively for EV applications, especially for the propulsion of HEV.
BS EN 61982-4 provides the safety test procedures and acceptance criteria of Ni-MH batteries (cells and modules) for EV application to evaluate their basic safety performance. For automobile applications, it is important to note the design diversity of battery packs and systems and specific requirements for cells corresponding to each of such designs.
As a user of BS EN 61982-4, you are provided with a basic level of safety test methodology and criteria with general versatility, which serves a function in common primary testing of cells or modules to be used in a variety of battery systems.
