4.4.6 Battery Management Board and Battery Module
The battery management board and the battery module are used for keeping the ultrasound system
on standby status after the AC power is disconnected. When the ultrasound system is on working
status, the battery is charged.
When the ultrasound system is on standby status and disconnected from AC power, the battery
provides 5V_Stb power for the ultrasound system to keep it on standby status.
The battery indicator is controlled by the battery management board and the battery module.
The design diagram of battery management board is shown as follows.
