Estimation of lead-acid batteries exploitation possibility in high-rate charge and partial state of charge mode

Lead-acid batteries exploitation possibility in pfrtial state of charge mode is demonstrated. Influence of this mode on chfracteristics of lead-acid batteries is studied.

Accelerated charge method of the lead-acid batteries. 1. Constant current stage of the charge

Strategy of the accelerated mode of the charge, including constant current charge to 80 % state-of-charge and a pulse charge by asymmetric current to a full charge is offered. Results of the first investigation phase devoted to studying of influence of a mode constant current charge on a resource of lead-acid accumulators are presented in this work. Various influence of size of an initial charge current on degradation of positive and negative active materials and possibility of charge of the accumulator to 80 % state-of-charge for 0.5 h is demonstrated.

Accelerated charge method of the lead-acid batteries. 3. Pulse charge

Strategy of the accelerated mode of the charge of the lead-acid batteries, including constant current charge to 80% state-of-charge and a pulse charge to 100% is considered. Influence of key parameters of a pulse charge (amplitude and duration of charge pulse, duration of a pause, the general duration of a pulse charge) on the efficiency of a charge and a heat-up of batteries are studied in this work.

Accelerated charge method of the lead-acid batteries. 2. Constant current charge

Strategy of the accelerated mode of the charge of the lead-acid batteries, including constant current charge to 80% state-of-charge and a pulse charge to 100% is considered. Various modes one – and two-stage constant current charges are studied in this work, and the estimation of influence of these modes on effectiveness ratio of a charge and a heat-up of batteries is yielded. The data, which allows reasonably choose the mode of the first stage of the accelerated charge to 80% state-of-charge, are presented.
