Introduction
Safety design and control requirements for lithium-ion battery packs for spacecraft
| Chapter | Main requirements | Technical parameters |
|---|---|---|
| 6.1 Safety design and control of single battery cells | - Select materials with good thermal stability and high safety - Fully sealed structure design, leakage rate ≤$1.0 imes10^{-7} \mathrm{Pa}\cdot\mathrm{m}^{3}/\mathrm{s}$ - Positive limit design and negative capacity excess design | The diaphragm covers the negative electrode sheet, and the shell is corrosion-resistant |
| 6.2 Component safety design and control | - Select components from qualified suppliers - Enough wire cross-section, avoid being too thin - Error-proof electrical connector design | Derating design, hole-type electrical connector |
| 6.3 Insulation safety design and control | - Double insulation design - Use highly mature insulating materials - Surface live parts protection measures | Insulation resistance ≥$100 \mathrm{M}\Omega$ (single body) ≥$20 \mathrm{M}\Omega$ (structure) |
Implementation suggestions
In spacecraft design, priority should be given to using GB/T 43927-2024 standard lithium-ion battery packs, and undergo rigorous testing and verification. Especially under extreme environmental conditions, such as high and low temperatures, radiation and vibration, the stability and safety of the battery packs must be ensured.
It is recommended to combine the FME(C)A analysis method in practical applications to comprehensively assess potential risks and formulate corresponding protective measures. At the same time, operators should receive professional training to ensure the correct use and maintenance of battery packs to avoid safety accidents caused by human errors.
