Description

Nickel-hydrogen battery pack support

Technical Field

The utility model belongs to the technical field of the nickel-hydrogen battery assembly technique of monomer and specifically relates to a nickel-hydrogen battery group support is related to.

Background

Six major speed increases were accomplished by the china railway from 4 months 1997 to 4 months 2007. In the last ten years, the general iron plan totally unifies vehicles with the speed of 80Km into a direct and fast train with the speed of 160Km, and simultaneously plans to fully start the re-boarding verification work of vehicle parts on Tibet railways. Through market research, 10 ten thousand railway vehicles are in total, most of the railway vehicles adopt lead-acid batteries and nickel-cadmium batteries as standby power supplies, and the two types of batteries are influenced by environmental protection and maintenance factors and gradually quit the market in the future. The nickel-metal hydride battery has the characteristics of environmental protection, safety, high specific power, good large-current charging and discharging performance, capability of being used at a wider temperature, easiness in recovery and the like, and can be successfully cut into the market of railway vehicles. It is understood that the requirement of railway vehicles can be met at home at present, the number of suppliers providing nickel-hydrogen batteries does not exceed 3, and the capacity can not meet the requirement of the railway market far.

In recent years, the national requirements for environmental protection are becoming stricter. In response to national environmental protection policies, the rail administration has a tendency to eliminate the use of lead-acid batteries and nickel-cadmium batteries on newly produced rail vehicles. In 2019, the general iron service office tries nickel-hydrogen batteries to replace lead-acid batteries and nickel-cadmium batteries on part of railway vehicles as auxiliary power supplies of the railway vehicles. The number of newly built 160Km trains is between 500 and 1000, 46 standard groups (8 carriages in each group) are produced in 2018, and 134 standard groups are already produced in 2019. The number of the vehicles will rise year by year in the future, and once the model selection scheme is determined, the vehicles cannot be easily transformed within 10-15 years, so that the nickel-hydrogen battery is a medium-long term development plan on the railway vehicle. However, the existing nickel-hydrogen single battery assembly structure is easy to loosen and is easy to cause poor contact, which will affect the normal operation of the battery and increase the frequency of maintenance.
