SOLAR POWERED AND BATTTERY OPERATED SYSTEMS AND METHODS FOR CONTROLLING THE SAME

摘要

A power supply system has a solar cell and a battery which comprises a plurality of modules. The number of modules used to supply electrical power to the load is controlled as well as the recharging of the modules, based on energy supply and demand data over a time period of multiple days. This enables the battery modules to be used more efficiently, and they can be charged and recharged less frequently on average, thereby extending the battery lifetime

主权项

1. A controller for controlling a power supply system, wherein the power supply system comprises a solar cell and a battery which comprises a plurality of modules,
wherein the controller, is configured to control electrical power to a load from the battery, wherein the controller is configured to control the modules used to supply the electrical power to the load and to control the recharging of the modules based on energy supply and demand data over a time period of multiple days, such that at any particular time the modules are in a charge and discharge cycling mode, and other modules are at rest, wherein the controller is adapted to control the number of modules used to supply the load to be fixed for the time period of multiple days.
