A smart battery charger is mainly a switch mode power supply (also known as high frequency charger) that has the ability to communicate with a smart battery pack's battery management system (BMS) in order to control and monitor the charging process. This communication may be by a standard bus such as CAN bus in automobiles or System Management Bus (SMBus) in computers. The charge process is controlled by the BMS and not by the charger, thus increasing security in the system. Not all chargers have this type of communication which is commonly used for lithium batteries.
An easy-to-maintain smart battery charger

This utility model discloses a convenient-to-maintain smart battery charger, relating to the application field of smart door lock battery chargers. It includes a door lock battery, with a charger movably mounted on the bottom of the battery. The charger has a circular groove at its bottom, and a column is positioned inside the circular groove. An L-shaped limiting groove is formed on the outside of the column, and a cap is movably mounted on the outside of the column. A limiting block matching the L-shaped limiting groove is provided on the inner side of the cap, and a spring connects the cap and the column. This utility model, by using the circular groove, cap, and column, can be used to store the charger's charging cable. Rotating the cap at a certain angle causes it to rise under the spring's return action, allowing the user to rotate and wrap the charging cable around the outside of the cap. After winding, pressing and rotating the cap again, using the L-shaped limiting groove and limiting block, secures the cap within the circular groove, thus achieving a concealed storage effect for the charging cable.

Motion platform
A hybrid motion simulator (100) comprises a platform (104) that moves relative to a base (102) in response to a respective driving force supplied by a motor arrangement (106). An energy storage system (112) is electrically connected between the motor arrangement (106) and an electrical power input (120) configured to receive an external single-phase electrical power supply (122). The energy storage system (112) comprises battery management system (118) that controls a smart battery charger (116) to charge a battery arrangement (114) using electrical power received from the electrical power input (120) such that: i) under a first load condition, electrical power from the electrical power input (120) is used to supply the motor arrangement (106) and to charge the battery arrangement (114); and ii) under a second load condition, the battery arrangement (114) is at least partially discharged to supply stored electrical power to the motor arrangement (106).
