1. A battery charging system for charging a battery comprising:
the battery providing electrical power to a load;
an electric machine charge source for charging the battery, the electric machine charge source including a prime mover configured to generate mechanical power and an electric machine connected to the prime mover and configured to convert the mechanical power generated by the prime mover into electrical power for charging the power source; and
a solar charge source for charging the battery, wherein the solar charge source is connected in parallel to the electric machine charge source, the solar charge source including:
a solar panel configured to absorb sunlight and generate electrical power from the sunlight, and
a solar charge controller connected to the solar panel, the solar charge controller including an automotive type transient suppression module configured to provide automotive type transient protection for the solar charge source from an automotive type transient,
wherein the solar charge controller further includes:
a maximum power point tracking (MDPT) portion configured to obtain solar cell data from the solar panel and determine power optimization information from the solar panel data;
a temperature compensation portion configured to obtain temperature data of the battery and determine correction information based on the temperature data; and
a startup and charge rate intelligence portion configured to obtain charge status data from the battery and determine charge optimization information based on the charge status data; and
a load control and output regulation portion configured to control and regulate electrical power sent to charge the battery based on the power optimization information obtained from the MPPT portion, the correction information obtained from the temperature compensation portion, and the charge optimization information obtained from the startup and charge rate intelligence portion.
