Electric power take-off system

An electric power take-off system for mounting to a truck body, the system comprising:

• a motor with an output shaft;
• at least one battery for providing electrical power to the motor;
• a fluid reservoir;
• a pump operably connected to the motor for pumping fluid through at least one conduit from the fluid reservoir to at least one truck function and for return of the fluid to the reservoir;
• a digital sensing unit for sensing at least one of fluid pressure or fluid flow rate within the conduit, the digital sensing unit comprising an output functionality;
• a selector to engage or disengage the existing power-take-off system;
• a motor controller in operable communication with the digital sensing unit and the motor for controlling the rotational speed of the motor;
• a charging unit for charging of the at least one battery, the charging unit comprising at least one outlet and a charging interlock, wherein the charging interlock prevents charging of the at least one battery until all safety interlocks are engaged and the truck body is configured for transit;
• and
• a data management system operable to collect data on at least one of (i) hours of operation of the electric power-take-off system, (ii) hours of operation of the existing power-take-off system powered by the internal combustion engine, (iii) fuel savings resulting from increased usage of the electric power-take-off system and reduced usage of the internal combustion engine, and (iv) calculated reduction of greenhouse gas emissions from increased usage of the electric power-take-off system and reduced usage of the existing power-take-off system, wherein the data management system is operable to wirelessly transmit data from the system to a server for transmission to a customer.

An electric power take-off system for mounting to a truck body to complement an existing power-take-off system powered by an internal combustion engine, the system comprising:

• a motor with an output shaft;
• at least one battery for providing electrical power to the motor;
• a fluid reservoir;
• a fluid pump operably connected to the output shaft of the motor;
• at least one fluid conduit connecting the fluid pump, fluid reservoir and at least one truck function;
• a digital sensing unit for sensing at least one of fluid pressure or flow rate within the at least one fluid conduit, the digital sensing unit comprising an output functionality;
• a selector to engage or disengage the existing power-take-off system;
• a system interlock rendering inoperable the electric power-take-off system when the internal combustion engine is in operation;
• a motor controller in operable communication with the digital sensing system and motor for controlling the rotational speed of the motor and thereby the fluid output of the pump, wherein the motor controller limits operation of the motor only to occasions of truck function operation initiated by the system operator and the resultant instantaneous demand of the truck function operation as determined by the digital sensing unit;
• a charging unit for charging of the at least one battery, the charging unit comprising at least one outlet and a charging interlock, wherein the charging interlock prevents charging of the at least one battery until all safety interlocks are engaged and the truck body is configured for transit;
• and
• a data management system operable to collect real-time data on at least one of (i) hours of operation of the electric power-take-off system, (ii) hours of operation of the existing power-take-off system powered by the internal combustion engine, (iii) fuel savings resulting from increased usage of the electric power-take-off system and reduced usage of the internal combustion engine, and (iv) calculated reduction of greenhouse gas emissions from increased usage of the electric power-take-off system and reduced usage of the existing power-take-off system, wherein the data management system is operable to wirelessly transmit data from the system to a server for transmission to a customer.
