AI Customer ServiceFor example a 26Ah lead acid battery (20 hour discharge rate) is approximately only 22Ah at the 5 hour discharge rate. Low weight - approximately one third of a similar capacity lead acid battery. Deep cycle - recharges up to 2000 times at 80% depth of discharge.
Three common SoC monitoring methods – voltage correlation, current integration, and Impedance Track are discussed. State of charge of lead acid battery is the ratio of the remaining capacity RC to the battery capacity FCC . The FCC (Q) is the usable capacity at the current discharge rate and temperature.
4 2H 2 O When a lead-acid battery is discharged, electrolyte and the active material on the plates of the battery are consumed to produce water and lead sulphate. When a lead-acid battery is charged, electrical energy is added to the battery, causing the water and lead sulphate to be consumed and produce electrolyte and active material.
State of charge of lead acid battery is the ratio of the remaining capacity RC to the battery capacity FCC . The FCC (Q) is the usable capacity at the current discharge rate and temperature. The FCC is derived from the maximum chemical capacity of the fully charged battery Q MAX and the battery impedance R DC (see Fig. 1) .
The chemical equation for a lead-acid battery during discharge is: PbO . 2 Pb 2H 2 SO 4 discharge → 2PbSO 4 2H 2 O The chemical equation for a lead-acid battery during charge is: PbO .
Lead acid batteries are typically used in the automotive industry, where they provide a high current pulse to start the vehicle, in traction applications, where they undergo periodic deep discharge and charge, and in stationary applications, where they remain in charged state most of their life.
