Abstract
An energy storage module for use in an electric vehicle, such as a lift truck, is disclosed. The energy storage module includes a bank of super capacitors or ultra-capacitors which are connected between the battery and the load. In operation, the energy storage module charges the capacitors, and uses the charged capacitors to level the load on the battery, limiting spikes in current draw, and assuring a substantially smooth discharge profile, wherein the battery discharge is substantially steady state. The energy storage module further includes sensors for determining when the battery and load are connected.
