When it comes to lithium batteries, float charging offers several benefits worth
Protection against failed voltage or current regulation should always be present in a Li-ion or lithium polymer charging scheme. In float charging, current entry beyond full charge is prevented by choosing a charge voltage less than or equal to the voltage naturally produced by the cell at full charge – which depends on the cell''s exact
The fully charged battery enters the float charge stage. A lower voltage is applied to maintain its full capacity, preventing overcharging and extending the overall lifespan of SLA batteries. 24V Lithium Battery Charging Voltage: A 24V lithium-ion or LiFePO4 battery pack typically requires a charging voltage within the range of about 29-30
Charging properly a lithium-ion battery requires 2 steps: Constant Current (CC) followed by Constant Voltage (CV) charging. A CC charge is first applied to bring the voltage up to the end-of-charge voltage level. You might even decide to reduce the target voltage to preserve the electrode. Once the desired voltage is reached, CV charging begins
It''s quite clear that it''s not possible to float charge Li-ion and Lipo cells, but LiFePo4 looks like quite different technology.
