Floor Cleaning Machine Battery Project

This floor cleaning machine LiFePO4 battery project shows how a 25.6V battery system can be configured for commercial floor scrubbers, sweepers and other professional cleaning equipment.

The battery specification is selected around the traction motor, brush motors, vacuum system, required cleaning shift, original lead-acid compartment, charger and machine weight requirements.

Commercial Floor Scrubber Battery Requirements

A floor cleaning machine can operate several electrical loads at the same time. Battery demand changes as the machine travels, applies brush pressure, dispenses cleaning solution and recovers water from the floor.

The battery review should cover:

  • Machine system voltage
  • Required cleaning time per charge
  • Traction-motor power
  • Brush-motor power and brush pressure
  • Vacuum-motor power
  • Average and startup current
  • Original lead-acid battery configuration
  • Battery-compartment dimensions
  • Machine weight and counterweight requirements
  • Main power connector and cable size
  • Charger voltage and charging current
  • Operating environment and exposure to cleaning chemicals

Reference 25.6V 100Ah Battery Specification

The following specification is an engineering reference for a medium-size 24V commercial floor scrubber. It is not presented as measured data from the cleaning machine shown in the photographs.

Machine System Voltage 24V
Nominal Battery Voltage 25.6V
Rated Capacity 100Ah
Nominal Energy 2560Wh
Continuous Discharge Current 100A
Peak Discharge Current Up to 500A for 1 second
Maximum Continuous Battery Output Approximately 2560W at 25.6V and 100A
Reference Average Current 25A planning value; replace with measured machine data
Calculated Cleaning Time Approximately 3.2 hours using 80Ah planning capacity at a 25A average load
Battery Charge Voltage 28.8V ± 0.4V reference specification
Reference Charger 29.2V 20A CC/CV LiFePO4 charger
Calculated Charging Time Approximately 5 hours from empty under ideal conditions

Important: Battery voltage, capacity, energy, current limits and charger settings are based on a published reference configuration. Average current and cleaning time must be confirmed with the intended floor scrubber before being presented as actual project results.

Reference Cleaning Machine Loads

Cleaning-machine power changes throughout the working shift. The traction, brush and vacuum motors do not necessarily operate at their maximum ratings at the same time.

Equipment Load Preliminary Power Range Operating Conditions
Traction Motor 400–600W Changes with speed, gradient, turning and machine weight
Brush Motors 500–800W combined Changes with brush diameter, pressure and floor resistance
Vacuum Motor 300–500W Operates during water-recovery cycles
Pump and Controls 50–150W Lower continuous or intermittent auxiliary load

These power ranges are preliminary engineering examples, not measured values from the pictured machine. Use motor nameplates, controller data and operating tests to establish the final load profile.

Combined Motor Load and Battery Current

The approximate current required by a combined 1500W cleaning load can be calculated as follows:

Battery Current = Equipment Power ÷ Battery Voltage ÷ System Efficiency

At 1500W, 25.6V and 90% overall efficiency, the calculated battery current is approximately 65A.

This represents a high-load condition rather than the average current over the complete cleaning shift. Current may be lower while the machine is turning, repositioning or operating with reduced brush pressure.

The equipment review should separate:

  • Average current over a complete cleaning route
  • Continuous traction current
  • Brush-motor operating current
  • Vacuum-motor operating current
  • Maximum simultaneous motor load
  • Startup current and its duration
  • Controller low-voltage cutoff
  • Regenerative current where applicable

Cleaning Time per Charge

Cleaning time depends on average current over the complete working cycle rather than maximum motor power alone.

Estimated Cleaning Time = Planning Battery Capacity ÷ Average Operating Current

Using 80Ah as the planning capacity, equal to 80% of the rated 100Ah capacity:

Average Current During Cleaning Calculated Cleaning Time
20A Approximately 4.0 hours
25A Approximately 3.2 hours
30A Approximately 2.7 hours
40A Approximately 2.0 hours

These calculations are planning examples rather than measured shift results. Floor type, brush pressure, travel speed, gradient, water recovery, operator use, motor efficiency and battery temperature all affect actual cleaning time.

Floor Scrubber Charger Compatibility

The reference system uses a 29.2V 20A CC/CV charger for the 25.6V 100Ah LiFePO4 battery.

At an ideal constant 20A output:

100Ah ÷ 20A = approximately 5 hours

Actual charging time may be longer because of charger efficiency, battery temperature, connected loads and charge-current tapering.

Before retaining the existing floor scrubber charger, confirm:

  • Maximum charging voltage
  • Continuous charging current
  • CC/CV or approved LiFePO4 charging profile
  • Charging connector and polarity
  • Automatic start and stop behavior
  • No incompatible equalization mode
  • No incompatible desulfation pulse
  • Low-temperature charging control

A matched LiFePO4 charger is recommended when the complete behavior of the existing lead-acid charger cannot be verified.

Battery Compartment, Weight and Machine Balance

The battery enclosure must be configured around the floor scrubber’s actual battery compartment, mounting structure, cable layout and service requirements.

Before approving the installation, confirm:

  • Maximum compartment length, width and height
  • Opening dimensions for battery installation and removal
  • Clearance above terminals and connectors
  • Cable bend radius and cable-routing space
  • Battery hold-down and mounting points
  • Maximum and minimum battery weight
  • Machine center of gravity
  • Traction and brush-pressure requirements
  • Fuse or circuit-breaker position
  • Protection from water, cleaning chemicals and impact

A LiFePO4 battery may weigh less than the original lead-acid bank. On some floor scrubbers, battery weight contributes to traction, stability or brush pressure. Counterweight requirements should therefore be reviewed before approving the conversion.

Lead-Acid to LiFePO4 Floor Scrubber Conversion

Many commercial floor scrubbers use two 12V lead-acid batteries connected in series or a dedicated 24V industrial battery bank. A lithium replacement should be selected from the complete machine specification.

The conversion review should cover:

  • Original battery models and connection arrangement
  • Original nominal and usable capacity
  • Original battery weight
  • Machine-controller voltage
  • Continuous and startup current
  • Battery-compartment dimensions
  • Main cable and connector ratings
  • Battery retention and counterweight requirements
  • Charger compatibility
  • Existing battery gauge or state-of-charge display

Smart BMS and Equipment Monitoring

The Smart BMS monitors voltage, current and temperature while protecting the battery against operation outside the approved limits.

Available functions can include:

  • Overcharge and over-discharge protection
  • Continuous and peak-current protection
  • Short-circuit protection
  • High- and low-temperature protection
  • Cell-voltage monitoring and balancing
  • State-of-charge reporting
  • Bluetooth battery monitoring
  • Optional CAN or RS485 communication

Many cleaning machines do not require battery communication. CAN or RS485 should only be added when the equipment controller or display requires battery data and a compatible protocol is available.
