Abstract

The invention discloses a modular lithium ion storage battery pack for a carrier rocket. The battery pack is formed by connecting a plurality of storage battery modules, wherein each storage battery module comprises a cylindrical lithium ion single battery, a battery bracket, a wiring board, a bridging sheet, a fastening pull rod and a clamping plate, the single battery, the battery support, the wiring board and the bridging sheet form a battery stack, the battery stack is fixed through the fastening pull rod and the clamping plate to form a storage battery module, a power output and signal detection mode of the bridging sheet welding the wires is adopted, the structure is beneficial to battery heat dissipation, and flight reliability is improved. The storage battery module is provided with an extensible through hole structure, so a plurality of modules can be extended to finally form a high-voltage and high-power lithium ion storage battery pack.

Description

technical field [0001] The invention belongs to the field of lithium ion accumulators, and in particular relates to a modular lithium ion accumulator group for launch vehicles. Background technique [0002] Lithium-ion battery packs for launch vehicles tend to use high-voltage and high-power electricity, and require good adaptability to the mechanical environment when used; lithium-ion battery packs for launch vehicle ground require a longer number of uses. According to the design form of the high-voltage single-module lithium battery pack, its production, testing and use all have a high degree of risk; the lithium-ion battery pack has serious performance attenuation problems and safety hazards of thermal runaway due to repeated high-current operations. Time-repeated use requires lithium-ion battery packs to be maintainable. However, domestic application technologies for high-voltage and high-power lithium-ion battery packs are relatively rare. The existing lithium-ion batte...
