Abstract
This paper studies the impact of Pulse Voltage as Desulfator to recover weak automotive Lead Acid Battery capacity which is caused by Sulfation. This technique is used to overcome the premature loss of battery capacity and speed up the process of charging and extend the lead acid battery life cycle 3 to 4 times compared with traditional charging methods using constant current. Sulfation represents the accumulation of lead sulfate on the electrodes (lead plates). This phenomenon appears naturally at each discharge of the battery, and disappears during a recharge. This is common with starter batteries in cars driven in the city with a load-hungry accessory. A motor in idle or at low speed cannot charge the battery sufficiently. Voltage pulse decompose the sulfate (PbSO4) attached to the electrode which is the main cause of the loss of capacity. In this paper, we study the effects of the recovery capacity of a Lead Acid Battery. Voltage pulses will be applied on a commercial automotive battery to collect data, using a charger/Desulfator prototype based on a PCDUINO. The experiment results show that there is improvement of Cold Cranking Amps level, and charge time duration of the Lead Acid Battery after using our prototype.
Highlights
In the last few years there has been a growing interest in batteries, they have revolutionized the way of storing electrical energy
The lead acid battery used were NS60, that has been used for 4-6 months on the vehicle, with the condition Voltage 12,29 Volt, 195 Cold Cranking APMS (CCA) starter power, according to standards Issued by Yuasa, NS60 starter has a standard power of 325 CCA.1
Aside from the value of the starter power of the lead acid battery, capacity can be seen through the value of the voltage, a battery which has a value voltage of 12.65 V is said to have a capacity of 100%, 12.40 V is said to have a capacity of 75% [10]-[13]
Summary
In the last few years there has been a growing interest in batteries, they have revolutionized the way of storing electrical energy. Its use is widespread and growing, it helps to have a reserve of electrical energy autonomous and mobile cell phones, photovoltaic systems, space equipment, laptops and other devices to public or industrial use. To use a battery effectively, it is necessary to understand its dynamics and discover the parameters which may affect its performance. The problem with these types of batteries is that they need to maintain their useful life capacity as long as possible and to optimize the use of their energy [1], [2].
