Pendulum clock driven by three weights as "gravity battery". An old and simple application is the pendulum clock driven by a weight, which at 1 kg and 1 m travel can store nearly 10 Newton-meter [Nm], Joule [J] or Watt-second [Ws], thus 1/3600 of a Watt-hour [Wh], while a typical Lithium-ion battery 18650 cell [2] can hold about 7 Wh, thus 2500 times more at 1/20 of the weight.
The storage state (S L (t)), at a particular time t, is the sum of the existing storage level (S L (t-1)) and the energy added to the storage at that time (E S (t)); minus the storage self-discharge, δ, at (t-1) and the storage discharged energy (E D (t)), at time t. Energy losses due to self-discharge and energy efficiency (η) are also taken ...
