摘要： An automatic rechargeable battery control module for a vehicle, such as a golf cart incorporates an automatic battery control system that automatically switches from charge to discharge modes with a single relay, thereby preventing the need to manually reset a relay switch due to an over or under voltage situation. An automatic battery control circuit is coupled with a battery management system and a relay contactor is opened and closed by a signal from the battery management system. The battery management system monitors a state of charge of the battery unit as well as current flow to and from a battery unit. The automatic rechargeable battery control module may have a state of charge output that is connected with a state of charge indicator to inform a driver of an approximate driving range or time remaining.

摘要： A battery-charge control device comprises an attachment-detecting unit, a temperature-obtaining unit, a voltage-obtaining unit, a threshold-value-determining unit, a determination unit, and a completion-processing unit. The threshold-value-determining unit determines, based on a battery temperature obtained by the temperature-obtaining unit, a completion-threshold-value corresponding to the battery temperature for determining necessity of charging when the attachment-detecting unit detects that the battery pack is attached to the battery charger. The determination unit performs a determination of whether a voltage obtained by the voltage-obtaining unit is equal to or greater than the completion-threshold-value determined by the threshold-value-determining unit when the attachment-detecting unit detects that the battery pack is attached to the battery charger. The completion-processing unit performs a specified battery-charge completion processing indicating unnecessity of charging of the battery by the battery charger when the determination unit determines that the obtained voltage is equal to or greater than the completion-threshold-value.
