BATTERY SUPPORTED ECOOKING TECHNOLOGIES WITH A DISCUSSION ON BATTERY SWAP MODELS

The document explores how battery storage can enable eCooking in areas with weak, unreliable, or non-existent electricity grids. It specifically proposes a Battery Swapping Model (BSM) where users lease batteries from a central station, reducing upfront capital burdens and ensuring professional battery maintenance. The paper identifies a 'Goldilocks Zone' for this model—informal urban settlements, humanitarian settings, and mini-grid edges—where population density and proximity to stations make daily swaps practical. It concludes that while promising, the BSM requires targeted pilots to determine financial and operational viability.

• Battery-enabled eCooking is particularly viable in three specific electricity contexts: areas with weak or unreliable grids, grids with time-of-use incentives to reduce peak demand, and entirely off-grid locations.
• The Battery Swapping Model (BSM) addresses three primary barriers to eCooking adoption: the difficulty of managing battery sustainability over a decade, the high upfront capital costs for households, and the need to leverage existing innovations from the electric vehicle sector.
• A 'Goldilocks Zone' exists for the viability of battery swapping, where batteries are large enough for cooking needs but light enough to transport, and the distance to the Battery Swapping Station (BSS) is neither too short (which would favor grid connection) nor too far (making daily travel impractical).
• The most promising markets for BSS include informal urban and peri-urban settlements, humanitarian or displacement settings, and the edges of mini-grids.
• Lithium Iron Phosphate (LFP) is a common chemistry for home solar, but Lithium Titanate (LTO) offers significantly higher cycle life, potentially delivering 10,000 cycles at 80% depth of discharge and up to 20,000 at 60%.
• For a typical household using energy-efficient measures, approximately 1.5 kWh of battery capacity per day is estimated to cover most cooking demands.
• Battery Swapping Stations can be powered through three main configurations: direct grid connection, off-grid renewables (solar PV, wind, or hydro), or a hybrid of both.
• Digital monitoring of battery usage is critical for accessing carbon finance, as it allows for the verification of actual emission reductions compared to biomass baselines, which can provide working capital for BSS developers.
• Socio-cultural dynamics, particularly gender roles, may impact BSS viability; in some traditional societies, women may not be permitted to travel daily to swap batteries, while men may be unwilling to perform a task associated with 'gathering cooking fuel'.
• BSS developers face a significant capital challenge because they must maintain a battery stock roughly 1.5 to 2 times the number of active users to ensure one set is always charging while the other is in use.
