Cleaning robots are used in commercial, industrial, healthcare, hospitality, and other working environments. Their battery systems need to support driving motors, cleaning brushes, vacuum systems, pumps, sensors, controllers, and communication modules throughout the operating cycle.
For cleaning robot manufacturers, battery selection involves more than choosing a specific voltage and capacity. The battery pack needs to match the robot’s power consumption, required runtime, peak current, charging system, installation space, BMS communication, operating environment, and production requirements.
Dongguan Yizhan Electronics Technology Co, Ltd. develops customized lithium battery packs and LiFePO4 battery packs for robots, AGVs, industrial equipment, e-bikes, medical equipment, and other applications. Yizhan provides OEM/ODM battery development covering cell configuration, BMS design, structural design, prototype production, testing, and mass production.
Part 1.What Is a Cleaning Robot Battery Pack?
A cleaning robot battery pack is a rechargeable power system designed around the electrical and mechanical requirements of a cleaning robot.
Depending on the equipment architecture, the battery may supply power to:
- Antriebsmotoren
- Brush motors
- Vacuum motors
- Water pumps
- Main control boards
- Navigation systems
- Sensoren
- Kommunikationsmodule
- Displays
- Safety systems
- Other auxiliary equipment
A complete lithium battery pack normally includes battery cells, a battery management system (BMS), electrical connections, protection components, wiring, connectors, and a mechanical enclosure.
For OEM cleaning robot projects, these components need to work as one power system rather than being selected independently.
Part 2.How to Calculate Cleaning Robot Battery Capacity
Battery capacity is commonly specified in ampere-hours (Ah), while battery energy is expressed in watt-hours (Wh).
Die grundlegende Beziehung lautet:
Batterieenergie (Wh) = Spannung (V) × Kapazität (Ah)
Zum Beispiel:
24 V × 40 Ah = 960 Wh
A 24V 40Ah battery therefore has a nominal energy rating of 960Wh.
However, the robot cannot necessarily use the entire nominal energy during every operating cycle. Actual usable energy can be affected by:
- Motorlast
- Average power consumption
- Peak current
- Batterietemperatur
- BMS-Einstellungen
- Batteriealterung
- Charging and discharging efficiency
- Required energy reserve
For this reason, battery capacity should be calculated from the robot’s actual operating requirements.
Part 3.How to Estimate Cleaning Robot Runtime
Runtime is related to battery energy and the robot’s average power consumption.
A basic calculation is:
Runtime (hours) ≈ Battery Energy (Wh) ÷ Average Power Consumption (W)
For example, if a cleaning robot uses a 24V 40Ah battery:
24 V × 40 Ah = 960 Wh
If the robot consumes an average of 300W:
960Wh ÷ 300W ≈ 3.2 hours
This is a theoretical calculation. Actual runtime can vary because cleaning robots do not normally operate at a constant power level.
Power consumption can change during:
- Start
- Beschleunigung
- Drehen
- Rampenklettern
- Brush operation
- Vacuum operation
- Water pumping
- Obstacle handling
- Navigation
- Standby operation
A battery design should therefore consider the complete operating cycle rather than using a single motor power value.
Part 4.Why Cleaning Robot Battery Voltage Matters
The battery voltage needs to match the robot’s electrical system.
Depending on the equipment, customized battery systems may use 12V, 24V, 36V, 48V, or other voltage configurations.
Battery voltage affects the current required for a given power level.
For example, a 1,000W load would theoretically require:
1,000W ÷ 24V ≈ 41.7A
At 48V:
1,000W ÷ 48V ≈ 20.8A
The actual current depends on system efficiency and operating conditions.
Voltage selection can therefore influence:
- Motor operation
- Continuous current
- Peak current
- Cable specifications
- Auswahl der Steckverbinder
- BMS-Konfiguration
- Charger selection
- Batterieaufbau
The battery manufacturer should evaluate these parameters together when developing an OEM battery pack.
Part 5.Continuous Current and Peak Current
Battery capacity does not define the complete electrical performance of a cleaning robot battery.
The battery pack also needs to support the current required by the robot.
For example, drive motors can require additional current during:
- Startup
- Beschleunigung
- Rampenklettern
- Drehen
- Obstacle crossing
Brush and vacuum motors can also create changes in the instantaneous power demand.
The battery design should therefore define both:
Kontinuierlicher Entladestrom
und
Spitzenableitstrom
The BMS needs to be configured according to the cell configuration, current requirements, protection strategy, and equipment operating conditions.
Part 6.BMS Requirements for Cleaning Robots
The Battery Management System is an important part of a custom robot battery.
A BMS can monitor and manage parameters such as:
- Zellspannung
- Pack-Spannung
- Ladestrom
- Entladungsstrom
- Batterietemperatur
- Ladezustand (SOC)
- Ladezustand
- Protection status
Zu den Schutzfunktionen können gehören:
- Schutz vor Überladung
- Schutz vor Überentladung
- Überstromschutz
- Kurzschlussschutz
- Schutz vor Überhitzung
- Überwachung der Temperatur
- Zellausgleich
For intelligent cleaning robots, communication between the battery and the robot controller may also be required.
Yizhan can develop customized BMS configurations according to the equipment requirements, including communication options such as CAN, UART, and RS485.
The communication protocol should be confirmed before battery development so that the battery can exchange the required information with the robot controller.
Part 7.Cleaning Robot Battery Charging Requirements
The battery charger needs to match the battery chemistry, voltage, charging voltage, charging current, BMS configuration, and charging method.
For lithium battery systems, charging generally involves a constant-current stage followed by a constant-voltage stage.
A simple charging-time estimation is:
Charging Time ≈ Battery Capacity ÷ Charging Current
Zum Beispiel:
40Ah ÷ 10A ≈ 4 hours
The actual charging time can be different because charging current changes during the charging process.
Cleaning robots may use different charging methods, including:
- Manual charging
- Plug-in charging
- Automatic docking
- Ladestationen
- Scheduled charging
For autonomous cleaning robots, the battery may need to work with the charging station and robot controller as part of an integrated charging system.
Charging requirements may include:
- Charge enable/disable control
- Ladezustand
- Überwachung der Temperatur
- Fehlersuche
- Charging communication
- Automatic docking compatibility
Part 8.Lithium-Ion or LiFePO4 for Cleaning Robots?
The battery chemistry should be selected according to the robot’s requirements.
Lithium-ion batteries can be considered when the project requires a compact battery configuration and specific energy characteristics.
LiFePO4 batteries can be considered for applications where cycle requirements, thermal characteristics, safety considerations, and operating conditions are important design factors.
The selection depends on:
- Required voltage
- Required capacity
- Verfügbarer Einbauraum
- Gewicht der Batterie
- Continuous current
- Peak current
- Runtime
- Cycle requirements
- Betriebstemperatur
- Ladevorgaben
- Target production volume
Yizhan develops both customized lithium-ion and LiFePO4 battery packs for different equipment applications.
Part 9.Mechanical Design of Cleaning Robot Battery Packs
A cleaning robot battery is not only an electrical component. Its physical structure needs to fit the equipment.
Important mechanical parameters include:
- Battery length
- Battery width
- Battery height
- Mounting holes
- Anschlussposition
- Cable outlet
- Enclosure structure
- Internal cell arrangement
- Gewicht der Batterie
- Kühlungsanforderungen
- Waterproof requirements
Cleaning robots can operate around water, cleaning solutions, dust, vibration, and repeated mechanical movement.
Therefore, the battery enclosure and sealing structure should be designed according to the actual working environment.
Yizhan provides customized battery structural design and 3D design support for OEM/ODM battery projects, allowing the battery structure to be developed around the customer’s available installation space.
