1. A battery manager comprising:
a) a connector for connecting an energy storage device; and
b) a controller configured to control:
i) one or more energy source switches configured for connecting one or more respective energy sources to the energy storage device to charge the energy storage device; and
ii) a first load switch configured for connecting the energy storage device to a first load; wherein
the controller is configured to perform steps of:
i) obtaining a time of need;
ii) obtaining a target state of charge for the energy storage device;
iii) obtaining a prediction of power production for at least one of the one or more respective energy sources;
iv) using the prediction of power production to determine a charge start time for the at least one of the one or more respective energy sources by which charging of the energy storage device from the at least one of one or more respective energy sources can be commenced such that the target state of charge is reached in the energy storage device by the time of need;
v) obtaining a target nominal state of charge;
vi) for the window of time between the charge start time and at least the time of need, determining:
(1) a predicted state of charge based on a simulation in which: a) the first load switch is open from the charge start time until the time of need and then closed at the time of need; and b) a corresponding at least one of the one or more energy source switches which corresponds to the at least one of the one or more respective energy sources is in a closed state at the charge start time until at least the time of need; and
(2) a corresponding detriment to longevity to the energy storage device due to exceeding the target nominal state of charge in the energy storage device;
vii) determining a value (‘cost’) of the detriment based on a correlation of detriment to longevity of the energy storage device and value;
viii) determining a first value of the energy stored at said excess of the target nominal state of charge based on a first unit value of energy, wherein the first unit value is a unit value of energy during a second window beginning at the time of need;
ix) determining a second value of energy stored at said excess of the target nominal state of charge based on one or more second unit values;
x) determining the difference of the first value minus the second value; and
xi) responsive to a determination that the difference is greater than the cost, performing steps of:
(1) opening the first load switch at the charge start time, thereby commencing charging of the energy storage device to accumulate energy in excess of the target nominal state of charge; and
(2) closing the first load switch at the time of need, thereby commencing discharging of the energy storage device to the first load.
