Charging capacity

Charging capacity is an ambiguous phrase that can refer to battery energy capacity, charger power or the electrical capacity available at a site. Those are different engineering quantities and should be named explicitly. Battery capacity is measured in kWh. Charger power is measured in kW. Site capacity describes the electrical power or current that the installation and grid connection can support. Where an older document says only "charging capacity", check which of these meanings is intended before comparing specifications.
