Internal energy storage unit The vacuum cleaner battery serves as an internal energy storage unit, receiving and storing energy from the charger to provide energy reserves for operation. Power delivery during use When the vacuum cleaner is operating, the battery converts stored electrical energy into current and drives the motor, main control board, and display unit to function. Voltage stability for reliable performance The battery outputs a relatively stable voltage, supplying the required operating level for the vacuum cleaner's electronic control system and motor. Smart management and protection The vacuum cleaner battery cooperates with the main control board and the battery management system to perform charging, discharging, and protective state changes as needed. Benefits at a glance Ensures reliable operation by maintaining energy reserves for continuous cleaning. Delivers consistent power to the motor and electronics for stable performance. Provides a stable operating voltage for the control system and motor. Works with the main control board and battery management system to manage charging, discharging, and protection. Use scenarios Scenario 1: Regular daily cleaning across multiple rooms with standard usage, benefiting from ready energy reserves for uninterrupted operation. Scenario 2: Prolonged cleaning sessions in larger spaces, where stored energy supports extended runtime without frequent recharging. Scenario 3: Cleaning cycles managed by the vacuum's control system and battery management system, enabling safe charging, discharging, and protective states during operation.
