In this mini do-it-yourself (DIY) project, we’ll design an LED table lamp that’s battery-operated and rechargeable. It will also feature light dimming so you can adjust the lamp. There are two basic types of lamps available on the market. A typical one with a 3 to 5-W LED bulb that works on a 230 V…
Understanding battery management systems
A battery-management system (BMS) is an electronic system or circuit that monitors the charging, discharging, temperature, and other factors influencing the state of a battery or battery pack, with an overall goal of accurately indicating the remaining time available for use. It’s used to monitor and maintain the health and capacity of a battery. Today’s…
