Definition
onboard system whose main function is to provide an aircraft with accessible energy for safe flight and landing
NOTE 1 ESS components include, but are not limited to, battery modules, the associated battery management system (BMS) (3.1.29), and all the associated wires, cabling and connections/terminals.
NOTE 2 The ESS includes a means by which limits are placed on accessible energy, e.g. due to cell temperature or state of charge, it also provides predictions of battery states with regard to the planned flight profile.
NOTE 3 State of function (SOF) (3.1.127) and state of health (SOH) (3.1.128) are key inputs to the ESS.
