Intelligent Satellite Battery Pack
DIOO (Deliver Integrated power On Orbit) battery pack is our early stage battery project engineered mainly for Low-Earth Orbit spacecraft — fully customisable to the mission voltage and capacity requirements. Project initiated early 2026, ESA BIC incubation starting mid-2026.
Purpose-built for orbit
Commercial off-the-shelf battery solutions are not designed for the radiation environment, vacuum conditions, and thermal extremes of low-Earth orbit. DIOO is a proprietary battery pack with smart battery management system built from the ground up for spacecraft applications — combining space-qualified cell selection, radiation-tolerant BMS electronics, and thermal control strategies developed specifically for LEO missions.
BMS electronics designed to operate reliably through the radiation environment of low-Earth orbit.
Passive thermal design handles the extreme hot/cold cycling of LEO orbit — from direct sun exposure to eclipse shadow with each 90-minute pass.
Redundant protection circuits, cell-level monitoring, and fault isolation to meet spacecraft safety requirements and range safety standards.
ESA-aligned testing plan
Sine and random vibration testing per ECSS-E-ST-10-03C to qualify mechanical integrity for launch loads.
Thermal vacuum cycling across the full operational range (−40 °C to +85 °C) to validate performance in the space environment.
Total ionising dose and single-event effects testing on BMS electronics to verify radiation tolerance for the LEO environment.
Charge/discharge cycle life testing simulating LEO eclipse conditions to validate capacity retention over a ≥2-year mission life.
Testing carried out in partnership with Ústav experimentálnej fyziky SAV (Slovak Academy of Sciences) and ESA BIC Slovakia facilities.
