Where is the recharge port for a 1995 Volvo wagon air conditioner?

Your question seems to conflate two different vehicle systems- the air conditioning system and car battery. While both systems contain components known as "chargers," the functions are different.

- An automotive battery is a reservoir for electrical energy and requires intermittent recharging to replenish the chemical reactions it provides. The port for this is under the hood and the charging process involves external sources of electricity.

- An air conditioning system, on the hand, is a closed loop of circulating refrigerating gas and does not feature recharging ports per se. Its charging process involves adding freon or other suitable refrigerants when the cooling effect drops.
