Abstract
Disclosed is a method of testing and assembling a power system of an electric or partial electric machine, the method including: assembling one or more sub-assemblies of the power system; testing one or more of the one or more sub-assemblies of the power system independently; adjusting one or more of the one or more sub-assemblies based on the testing; assembling each sub-assembly in a pre-determined location of the electric or partial electric machine; and testing the assembled power system of the electric or partial electric machine.
Claims20
A method of testing and assembling a power system of an electric or partial electric machine, the method comprising:
- assembling one or more sub-assemblies of the power system;
- testing one or more of the one or more sub-assemblies of the power system independently;
- adjusting one or more of the one or more sub-assemblies based on the testing;
- assembling each sub-assembly in a pre-determined location of the electric or partial electric machine;
- and
- testing the assembled power system of the electric or partial electric machine.
A power system for an electric or partially electric machine, comprising:
- a first sub-assembly including a genset;
- a second sub-assembly including one or more batteries;
- and
- a third sub-assembly including a motor powered by the genset or the one or more batteries,
- wherein each of the first sub-assembly, the second sub-assembly, and the third sub-assembly is tested separately from each of the others of the first sub-assembly, the second sub-assembly, and the third sub-assembly outside of the electric or partially electric machine, and wherein each of the first sub-assembly, the second sub-assembly, and the third sub-assembly is assembled in the electric or partially electric machine after testing.
A method of testing and assembling a power system of an electric or partial electric machine, the method comprising:
- assembling a first sub-assembly including a genset;
- assembling a second sub-assembly including one or more batteries;
- assembling a third sub-assembly including a motor powered by the genset or the batteries;
- testing one or more of the first sub-assembly, the second sub-assembly, and the third sub-assembly independently of each of the others of the first sub-assembly, the second sub-assembly, and the third sub-assembly;
- adjusting one or more of the first sub-assembly, the second sub-assembly, and the third sub-assembly based on the testing;
- assembling each of the first sub-assembly, the second sub-assembly, and the third sub-assembly in a respective pre-determined location of the electric or partial electric machine;
- coupling each of the first sub-assembly, the second sub-assembly, and the third sub-assembly to the others of the first sub-assembly, the second sub-assembly, and the third sub-assembly;
- and
- testing the assembled electric or partial electric machine, wherein testing includes providing power to the motor from one of the genset or the batteries.
