Provided are systems and methods for a public standard interface including a Battery Management System that allows for communication between an alternative energy source and a material handling vehicle. The alternative energy source may be a Lithium Ion Battery, a fuel cell, or another non-lead acid based battery. The Battery Management System is coupled with a CAN bus that allows for communication between the material handling vehicle and the alternative energy source. The CAN bus communicates information such as a type of the energy source, energy output limits, electric current limits and information such as an energy demand profile of the vehicle. Also included is an interface between the Battery Management System and Charger Control System.

Systems and methods for a public standard interface for material handling vehicles

A propulsion drive system is operated by a controller to propel an industrial vehicle along a path in an unmanned mode. An autonomous processor module sends commands to the vehicle controller in response to messages received via a communication network from a guidance and navigation system. The guidance and navigation system transmits a message over the communication network, wherein that message contains a first numerical value specifying the velocity and a second numerical value specifying an amount that the propulsion drive system is to turn a wheel of the industrial vehicle. The message also specifies a maximum speed limit and indicators commanding that a load carried by the industrial vehicle be raised and lowered. The autonomous processor module transmits a feedback message indicate actual vehicle operating parameters to the guidance and navigation system.

Communication technique by which an autonomous guidance system controls an industrial vehicle

A state-of-charge indicator system monitors the battery current and voltage during operation of a lift truck. Selected current and voltage samples are used to calculate the internal battery resistance and this is employed to calculate a &ldquo;dynamic&rdquo; battery voltage. This dynamic battery voltage is used as input to a stored look-up table which provides a battery state-of-charge value.
