How to charge and discharge a battery simultaneously?

No, the battery is not charging and discharging at the same time. It can do one or the other but not both. When the charging system (solar panel or alternator) is below the voltage of the battery, the battery is going to supply the needed current. It can supplement the charge coming from the charging system. The battery is not being charged.
