Question ENE 02

ENE-02 How much usable battery energy and reserve does each kiosk need for the agreed outage, including older batteries, hot or cold conditions and power-conversion losses?

Why this matters

Knowing the energy actually available lets people choose a service that can last through the planned disaster scenarios.

What to bring back

Compare battery-capacity and service-schedule options. Show the maker's stated capacity beside usable energy, ageing and temperature assumptions, protected reserve, discharge limits and how service changes over time in each outage.

What we know so far

• Straddie Disaster Kiosk Pitch.pdf — reviewed source; public copy can be added through the evidence process
• GPT Straddie Disaster Kiosks.pdf — reviewed source; public copy can be added through the evidence process
• Professional review and comparison of proposed improvements (When this work overlaps professional or public-authority responsibilities, compare the proposal and Luke's research with applicable industry/global best practice and relevant legal-engine sources. Record differences, reasonable improvements and deficiencies, with the responsible reviewer and response. Routine authorised drafting and wiki work can advance.)

AI-generated potential answers

For discussion and review · research checked 2026-10-20. These are AI-generated options and transfer assessments. The user's request and research method identify the source of this work. The source catalogue states what the references establish. The decision and approval record retains its own status.

Size storage from usable watt-hours and the agreed service schedule, then show reserve, ageing, temperature and conversion assumptions explicitly. Compare at least two battery sizes and a lower-power service mode. Treat a protective battery cut-off as the last boundary, with planned service reduction beforehand.

Usable-energy comparison

AI-generated adaptation of an existing pattern. Compare documented lithium battery/BMS combinations against measured loads. Use the selected maker's discharge and temperature limits; show how much service remains after reserve and ageing allowances, including a zero-solar period.

Research basis: Lithium NG battery manual: operation.

Separate essential-service reserve

AI-generated future concept. Explore independently protected storage for a modest notice and message relay, separate from intensive compute. A future module could display its measured remaining service allowance and preserve a dated notice if both supplies end.

Research basis: E Ink technology benefits.

Examples and local differences

• Community hubs with energy backup systems: AI transfer assessment: Community hubs combine storage with other energy sources to sustain useful services. Local difference to check: An individual kiosk needs its own load and reserve calculations; hub capacity figures do not transfer.

Evidence to bring back next

• Run a complete discharge/recharge trial within manufacturer limits.
• Review battery location, thermal limits, protection and replacement assumptions with the designer.
