1. A hybrid energy storage module (ESM), comprising:

  • a bus lead;

    a first high-power module connectable to the bus lead, the first high-power module including a high-power DC/DC converter and an ultracapacitor or a supercapacitor;

    a second high-power module connectable to the bus lead, the second high-power module including a DC/DC converter and a lithium-ion battery of a phosphate or manganese descriptor or nickel metal hydrate chemistry; and

    a controller operably connected to the first high-power module and the second high-power module,wherein the controller has (a) a pulse mode wherein the controller connects the first high-power module to the bus lead, and (b) an extended mode wherein the controller connects the first high-power module and the second high-power module to the bus lead to supplement electrical power applied to the lead with power from a low-power module according to electrical load on a power bus.
