Abstract:
We completed our internship at Rahimafrooz Batteries Ltd. (RBL) located at West Panisail, Zirani Bazar, Gazipur, Dhaka from 23rd December, 2012 to 8th January, 2013 (including Friday) and this internship report is the result of those 15 days attachment with the Rahimafrooz Batteries Ltd. (RBL). During our internship period we gathered practical experiences on topics related to lead acid battery production, different mechanical equipment which we have theoretically learned in Electrical Machine and Renewable Energy courses. In this report we have focused on the manufacturing process of lead acid battery which is manufactured in Rahimafrooz Batteries Ltd.
(RBL). Rahimafrooz Batteries Ltd. (RBL) manufactures around 200 types of automotive and customized industrial batteries. With the help of the factory engineers we observed the production floor of different sections, different machines such as grid casting machine, lead oxide mill, pasting machine etc. and understood the manufacturing process of the lead acid battery. We acquired knowledge about various types of batteries, charging and discharging process of lead acid battery, manufacturing process of lead acid battery and were introduced with different machines such as plastic molding machine, curing oven, Positive Dry Oven (PDO), Inert Gas Oven (IGO) etc.
Description:
