Which Battery is best for a Floor Care Machines?
Floor Care machine batteries will be deeply cycled (80% Depth of Discharge - DoD) regularly and often operated in a Partial State of Charge (PSOC) situation. The batteries will need high power capability to support the surge current demanded by electric motors, pumps and vacuums when they start. If the battery is Lithium, the BMS will also need to be hardened to tolerate the energy backfeed (EMF Spike) when a motor is stopped and electrostatic discharges (ESD).
Batteries for floor care machines should ideally be maintenance-free and be able to accept frequent short charges or ‘opportunity charging’ without degradation in long-term performance. Also, low-quality charging systems may not stop when they should and, therefore, regularly ‘over-charge’ the battery, degrading its useful life. Lithium batteries should integrate with the on-board charger. State of Charge (SOC) monitoring is beneficial to operators.
