To maximize your vehicle's battery health, most manufacturers suggest keeping the battery above 20% and to minimize fast charging as the battery nears full capacity (typically around 80%). Generally, if the battery is within a 20-80% range and you're confident you have enough of a charge to get home, then you may want to skip the charging session or opt to use an L2 charger.
You can review your owner's manual for more specifics. If you have questions about how often and to what percentage to charge your vehicle, you should contact the manufacturer.
