Method of rebuilding a used piece of equipment comprising replacing an interal combustion engine with a rechargeable battery power system
Conventional internal combustion engine technology has been around for decades and historically has been the primary power source for virtually all industrial equipment. It relies on carbon-based fuels, is loud, polluting, and the machines it powers are expensive to operate and maintain. A self-contained, rechargeable battery system is provided that possesses superior power than comparable diesel and gas engines. The rechargeable battery power system generates zero emissions, is virtually maintenance free, is quiet, and recharges overnight via a standard electrical outlet. The rechargeable battery power system can be installed in new and used construction equipment (light towers, excavators, generators) and may be used wherever a source of power is required, for example, in vans and boats, and in supplemental power systems including smart grid applications. It can be safely used indoors, in neighborhoods and other locations sensitive to the side effects of internal combustion engines.
1. A method of rebuilding a used piece of equipment comprising the steps of:
providing the used piece of equipment, and the used piece of equipment is powered by an internal combustion engine and the used piece of equipment has a frame;
extracting the internal combustion engine from the used piece of equipment;
modifying the frame such that the frame is capable of supporting a support plate and joining the support plate to the frame;
providing a battery assembly having a battery housing and the battery assembly having a battery, and disposing the battery in the battery housing and connecting the battery housing to the support plate;
providing the battery with first and second module banks and wherein the first module bank is made from a first group of modules and the second module bank is made from a second group of modules and wherein each of the first and second groups of modules are each made from individual modules and providing each individual module with individual cells and electrically connecting the cell;
installing a variable frequency motor driver and a variable frequency AC induction motor such that they are supported on a support structure affixed to the frame;
extracting a hydraulic pump and a pump cooling system for cooling hydraulic fluid pumped by the hydraulic pump from the used piece of equipment and relocating and installing the hydraulic pump and the pump cooling system on the frame such that the hydraulic pump and the pump cooling system are relocated on the used piece of equipment;
providing a battery management system;
connecting the battery management system to the variable frequency motor driver and connecting the battery management system to the battery, and connecting the variable frequency motor driver to the variable frequency AC induction motor such that the variable frequency AC induction motor can be powered by the battery;
providing a cab and joining the cab with the frame;
providing a throttle and connecting the throttle to the variable frequency motor driver and disposing the throttle in the cab;
providing a visual display and connecting the visual display to the battery management system and the variable frequency motor driver; and,
disposing the visual display in the cab.
2. The method of rebuilding a used piece of equipment according to claim 1 further comprising: providing a separator support plate and disposing the separator support plate in the battery housing such that the separator support plate separates the first and second module banks from one another.
3. The method of rebuilding a used piece of equipment according to claim 1 further including providing a service provider entity wherein the service provider entity purchases the used piece of equipment and removes the internal combustion engine and installs the battery for powering the used piece of equipment and sells the used piece of equipment to a consumer entity.
