OverviewPower management and distributionSolar array wingBatteriesStation to shuttle power transfer system
The power management and distribution subsystem operates at a primary bus voltage set to Vmp, the peak power point of the solar arrays. As of 30 December 2005, Vmp was 160 volts DC. It can change over time as the arrays degrade from ionizing radiation. Microprocessor-controlled switches control the distribution of primary power throughout the station. The battery charge/discharge units (BCDUs) regulate the amount of charge put into the battery.

The International Space Station (ISS) primary Electric Power System (EPS) was designed to utilize Nickel-Hydrogen (Ni-H2) batteries to store electrical energy.
S4 Performance S4 Capacity Data has been trending well within the expected range of capacity loss based on battery life performance test data and model predictions.
Altogether, the four sets of arrays are capable of generating 84 to 120 kilowatts of electricity – enough to provide power more than 40 homes on Earth. To put this in perspective,
Eight solar array wings supply power at an unprecedented voltage level of 137 to 173 Vdc that is converted to a nominal 124 Vdc to operate equipment on the ISS. The Space Shuttle and most

A photovoltaic (PV) electric power generation subsystem was selected for the space station. A PV system has solar arrays for power generation and chemical energy storage (Nickel-hydrogen) batteries to store excess solar array energy during periods of sunlight and provide power during periods when the station is in Earth’s shadow (eclipse).
Since the station is often not in direct sunlight, it relies on rechargeable lithium-ion batteries (initially nickel-hydrogen batteries) to provide continuous power during the "eclipse" part of the orbit (35 minutes of every 90 minute orbit).
Public Use Permitted. The International Space Station (ISS) Electric Power System (EPS) currently uses Nickel-Hydrogen (Ni-H2) batteries to store electrical energy. The batteries are charged during insolation and discharged during eclipse.
The Space Shuttle and most other spacecraft operate at nominal 28 Vdc, as does the Russian ISS segment. The higher voltage meets the higher overall ISS power requirements while permitting use of lighter-weight power lines. The higher voltage reduces ohmic power losses through the wires.
