NOVELTY - The method involves determining (1601) whether cycle delay is elapsed. A determination is made whether counter value is equal to second count parameter (1602). A battery is disconnected (1604) from a battery charger. A determination is made whether battery storage mode is enabled (1605). Determination (1608,1609) are made whether battery voltage is greater than preset voltage. The battery boost charging is enabled (1610). The battery is connected (1611) to charger. A determination is made weather counter value is equal to ninth count parameter. The counter value is reset (1613).    USE - Method for monitoring and controlling battery charging in recreational vehicle electrical/environmental subsystem (RVEES) such as battery temperature, battery voltage, overall system voltage, battery disconnect relay, vent fan, solar panel, cabin temperature, temperature alarm, power converter module, temperature sensitive power converter, parallax (RTM: a division of Connecticut Electric Inc.) power supply, load management controller, alternate current (AC) distribution controller, transfer switch, AC/generator input, storage tank sensor, pump and electrical load.    ADVANTAGE - Since the time, unloaded battery voltage measurements and boosted battery charging are used, the battery is optimally charged on a continuous basis. The battery charging in recreational vehicle electrical/environmental subsystem is monitored and controlled, the lifespan of a battery monitored and/or controlled by the overall RV user interface is optimized. Since the battery voltage is monitored based on timing parameters, the variety of charging cycles is initiated for the battery to ensure maximum battery availability and useful life.
