In this paper, a new method of charging and repairing lead-acid batteries is proposed. Firstly, small pulse current is used to activate and protect the batteries in the initial stage; when the current approaches the optimal current curve, the phase constant current charging is used instead, when the voltage is low.
Abstract A pulsed-current technique is evaluated for the rapid charging of lead/acid cells that are prepared with either low-antimony or lead-calcium-tin grids. For comparative purposes, these cells are subjected to repetitive reserve-capacity cycling under either pulsed-current or conventional, invariant-current recharge.
There are some problems in lead-acid batteries, such as short service life and decreasing capacity. In this paper, a new method of charging and repairing lead-acid batteries is proposed.
If you only have DC power and charge the lead-acid battery, you can do this by applying this DC voltage to a DC regulator and some additional circuits before using the lead acid. Car battery is also a lead acid battery (Figure 1), as you can see in the block diagram above, DC voltage is supplied to the DC voltage regulator.
It has been established that the capacity and cycle-life performance of batteries can be enhanced by an increase in electrolyte temperature up to ~50 . Therefore, it must be determined whether the cycle- life improvement with pulsed-current charging is not simply a temperature effect.
In a previous study, we reported the application of pulsed-current techniques to the formation of lead/ acid battery plates. The results showed that the efficiency of the process was 15-30% greater with a pulsed- current than with an invariant-current schedule.
