Abstract

Disclosed is a system configured to deliver power to a load in a transport vehicle, the system having: (a) a battery; (b) a super capacitor bank; (c) a bidirectional DC/DC converter configured to transfer power to/from the super capacitors in order to absorb/supply power from/to the load, and configured to transfer power between the super capacitors and the battery and/or the load in order to charge the super capacitor from the battery or load or charge the battery/load from the super capacitors in a controlled way (d) a hybrid controller, the hybrid controller configured to identify when pulsed power is required to/from the load and instructing the DC/DC converter to supply/absorb power to/from the load from/to the super capacitor bank and to identify when power needs to be transferred between the super capacitor and the battery/load to charge or discharge the battery/load and/or super capacitor.

Dependent claims

A transport vehicle power system configured to deliver power to a load in a transport vehicle, the transport vehicle power system comprising:

(a) a battery;
(b) a super capacitor bank comprising a plurality of capacitors;
(c) a bidirectional DC/DC converter:
(i) the bidirectional DC/DC converter, in order to regulate a pulsed power applied to the battery, configured to either:
(1) transfer power to the super capacitor bank in order to absorb power from the load;
or
(2) transfer power from the super capacitor bank in order to supply power to the load;
and
(ii) the bidirectional DC/DC converter configured to transfer power between the super capacitor bank and the battery and/or the load in order to charge the super capacitor bank from the battery or the load, or charge the battery/load from the super capacitor bank in a controlled manner using a hybrid controller in order to minimize battery stress and battery degradation;
and
(d) the hybrid controller:
(i) the hybrid controller, in order to minimize power transients on the battery, configured to identify:
(1) when pulsed power is required to the load and instructing the bidirectional DC/DC converter to supply power to the load from the super capacitor bank, or
(2) when pulsed power is required from the load and instructing the bidirectional DC/DC converter to absorb power from the load to the super capacitor bank;
and
(ii) the hybrid controller, in order to minimize battery stress and battery degradation, configured to identify when power needs to be transferred between the super capacitor bank and the battery/load to charge or discharge the battery/load and/or the super capacitor bank.
