Definitions and Symbols
In addition to those provided in GB/T 2900.11, the following definitions apply throughout this Standard.
3.1
Sealed cell Means the battery that remains closed when operating within the specified design scope; however, once the inner pressure increases and outstrips the pre-set value, gas is permitted to escape via a pressure release device which may be reset or may not.
3.2
Symbols C3 – nominal capacity at 3-hour rate. I3 – discharge current at 3-hour rate, which value equals 1/3C3(A).
V – voltage drop, represented in V, from V1 (the peak value of charge voltage attained when charged at a certain current) to V2 within the specified time limit, i.e., V

PREFACE
This voluntary national standard has been developed with reference to IEC 61436 (1998) “Sealed nickel-metal hydride rechargeable single cells”. The provisions herein have been set out based on the technical requirements for electric road vehicles, in consideration of the local present level of nickel-metal hydride batteries; both the current demands and future development have been taken into account, i.e., this Standard has been worked out based on the local latest level. In this Standard, Annex A shall be informative. This Standard was proposed by the State Administration of Machine-making Industry. This Standard shall be subject to the administration of SAC/TC114. It was drafted by No. 18 Research Institute of Electronics, Ministry of Information Industry. The following units also participated in the drafting: National Engineering & Development Center of Hi-tech Innovative Energy Storage Materials, General Research Institute for Non-ferrous Metals, Shenyang Zhongliao Sanpu Batteries Co., Ltd., Guangdong Shili Group Co., and State-owned No. 755 Plant. Main drafters are: Wang Jie, Wang Jiqiang, Mao Licai, Zhan Feng, Liu Yuanhong, and Duan Qiusheng.
