Power supply apparatus and components thereof (venting)

A power supply apparatus comprising a main housing, a battery assembly and battery management circuitry;

• wherein the battery assembly comprises a plurality of batteries, the batteries having safety vents which are distributed on a first surface of the battery assembly for releasing gaseous discharge,
• wherein the main housing comprises a battery compartment in which the battery assembly is held,
• wherein the battery compartment comprises a discharge chamber which is in fluid communication with the safety vents
• wherein a venting aperture or a plurality of venting apertures is formed on the discharge chamber, and wherein a thermal sensor or a plurality of thermal sensors is provided on the discharge chamber,
• wherein the thermal sensor is configured to detect temperature inside the battery compartment and to deliver temperature information to the battery management circuitry, and
• wherein the battery management circuitry is configured to activate a counter-measure or a temperature conditioning arrangement to condition temperature of the battery assembly when the temperature detected by the thermal sensor or the plurality of thermal sensors reaches an activation threshold temperature.
