In this communication, the measured behaviour of a lead-acid battery bank within a stand-alone residential solar photovoltaic (PV)-genset-battery hybrid power system in Canada is presented and discussed. In order to capture rare field-based battery performance data, a newly commissioned lead-acid battery bank was equipped with a battery monitoring device capable of logging voltage, current, temperature and amp-hours every 30 s for the life of the battery. The measured data captures a severe loss of battery capacity due to a combination of short-term deep discharge and extended partial state of charge operation—conditions not unusual during winter season PV-genset-battery hybrid power system operation. Subsequent manual override of the system control set points to encourage gradual battery overcharge are shown to recover the lead-acid battery bank’s performance over the following three months. Limitations of the power conversion system’s battery management approach are discussed and a novel closed loop control system for improving lead-acid based PV-genset-battery hybrid system performance is rationalized and proposed for further research.

<p><em>Abstrak–</em><strong>Pengecasan dengan menggunakan teknik pulsa arus adalah salah satu teknik yang dapat digunakan untuk mengatasi kehilangan kapasitas aki secara prematur. Teknik ini bisa mempercepat proses pengecasan aki dan memperpanjang siklus hidup sebesar 3 sampai 4 kali dibandingkan dengan pengecasan konvensional dengan arus konstan. Lebih panjangnya siklus hidup baterai berbahan <em>lead acid</em> (BLA) ini dikarenakan teknik pulsa tegangan bersifat sebagai desulfator yaitu pengurai Kristal senyawa timbal sulfat (PbSO<sub>4</sub>) yang menempel pada elektroda dan menjadi penyebab utama BLA kehilangan kapasitas secara prematur. Penelitian dilakukan untuk melihat efek pemulihan / desulfator, dimana BLA yang sudah lemah karena sudah terpakai di <em>treatment</em> dengan pulsa tegangan akan mengembalikan kapastias simpan BLA, menggunakan <em>prototype</em> yang telah dibuat. Dari eksperimen yang dilakukan terlihat peningkatan nilai Daya <em>starter</em> dan peningkatan durasi pembebanan pada BLA.</strong></p><p> </p><p><em>Abstract – </em><strong>Battery charging using pulse technique is a technique that can be used to overcome the premature loss of battery capacity. This technique can speed up the process of charging and extended battery life cycle 3 to 4 times compared with conventional charging using constant current. The Longer  life cycle of Lead Acid Battery is because the technique has desulfator effect. Voltage pulse decomposite timbale sulfate (PbSO<sub>4</sub>) attached to the electrode which is  the main cause of the premature loss of capacity . This study will investigate the effects of the recovery of battery capacity for used weak Lead Acid Battery. Voltage pulses will be applied to the battery using a charger/desulfator prototype. The experiment results show that there is improvement of Cold Cranking Amps Level and Load time duration of the Lead Acid Battery.</strong></p><p><em> </em></p><p><strong><em>Keywords –</em></strong><em> BLA(Lead Acid Battery) desulfator, pulse voltage, lead sulfate</em></p>

<p><em>Abstract<strong> – </strong></em><strong>Baterai berbahan <em>Lead Acid</em> (BLA) digunakan pada hampir semua kendaraan termasuk angkutan umum beroda empat. Kecepatan penuaan pada proses penuan BLA sangat dipengaruhi oleh cara penggunaan BLA. Pengisian yang berlebihan, akan mengakibatkan korosi dan mempercepat  penguapan  air. Bertambahannya siklus pembebanan dalam (<em>depth of discharge</em>), degradasi massa postifif akan terakselerasi. Beberapa kerusakan Selain itu pembebanan yang berlebihan juga akan mengakibatkan lepasnya masa positif dari grid karena proses pembebanan BLA yang melebihi seharusnya. Keawetan BLA pada Angkutan umum perkotaan sangat ditentukan pola penggunaannya. Karakteristik operasional yang sering menuntut kendaraan berhenti akan memiliki pengaruh jenis kerusakan tertentu pada komponen BLA Penelitian ini akan mengeksplorasi karakterristikoperasional angkutan perkotaan. Dengan diketahuinya karakteristik operasionalnya maka dapat disiapkan langkah antisipatif dan prediktif  dalam hal perawatan dan penggunaan BLA sehingga masa servis BLA akan lebih panjang serta meningkatkan efisiensi biaya para pemilik angkutan perkotaan.</strong></p><p><strong> </strong></p><p><strong><em>Keywords</em></strong><strong> – </strong><em>BLA (Lead Acid Battery), transportasi perkotaan, masa servis BLA</em><strong></strong></p><p> </p><p><em>Abstract - </em><strong>Lead Acid batteries (BLA) is used for most of all public transport vehicles including four-wheel drive. Speed of aging battery  is strongly influenced by operational pattern and maintenance of public transport vihicle. Overcharging, will result in corrosion and accelerate the evaporation of water. With more loading cycles in the (depth of discharge), positive mass degradation will be accelerated. Moreove,  excessive load will also result in the release of a positive mass of the grid due to the excessive load can be taken by battery. The durability of the Battery on urban public transportation is also determined patterns of use. For example, operational characteristics a vehicle that often requires stopping  would have the effect of certain types of damage to the components of the battery.  This study will explore urban transport operational characteristics. By knowing the operational characteristics, a set of procedures can be set up in order to prevent premature loss of battery capacity. By using apropriate predictive maintenance procedure, the life span of battery will be longer, thus will  improve the cost efficiency for starter lead acid battery replacement. </strong></p><p><strong> </strong></p><p><strong><em>Keywords</em></strong><strong> – </strong><em>BLA (Lead Acid Battery), urban transport, service life BLA</em><strong></strong></p>
