<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>

The aging of lithium-ion batteries (LIBs) is a crucial issue and must be investigated. The aging rate of LIBs depends not only on the material and electrochemical performance but also on the working conditions. In order to assess the impact of vehicle driving conditions, including the driving cycle, ambient temperature, charging mode, and trip distance on the battery life cycle, this paper first establishes an electric vehicle (EV) energy flow model to solve the operating parameters of the battery pack while working. Then, a powertrain test is carried out to verify the simulation model. Based on the simulated data under different conditions, the battery capacity fade process is estimated by using a semi-empirical aging model. The mileage (Ф) traveled by the vehicle before the end of life (EOL) of the battery pack is then calculated and taken as the evaluation index. The results indicate that the Ф is higher when the vehicle drives the Japanese chassis dynamometer test cycle JC08 than in the New European Driving Cycle (NEDC) and the Federal Test Procedure (FTP-75). The Ф will be dramatically reduced at both low and high ambient temperatures. Fast charging can increase the Ф at low ambient temperatures, whereas long trip driving can always increase Ф to varying degrees.
