Battery Charging Techniques — Lesson 5

This lesson covers the different methods of charging batteries, particularly focusing on those used in electric vehicles. It explains the two main methods: constant current charging and pulse charging. The lesson also discusses the importance of communication between the battery and the charger, which helps maintain the charging rate and cut off when necessary. It further highlights the impact of temperature during charging and discharging on the life cycles of batteries. The lesson concludes by emphasizing that the cost of a battery is not just the initial capital cost but also depends on life cycles, which in turn are influenced by the rate of charging and discharging, temperature, and depth of discharge.
