What companies manufacture electric car charging stations?

Notes for clarification of the terminology:

Level 1 , Level 2, and Level 3 EV chargers offer 120Vac and 240Vac, respectively. The charger for EVs that converts the grid power into DC and recharges batteries is integrated directly into the BEV and is controlled by the BEV’s batteries management system (BMS).

The device that connects to an electric vehicle for secure, standard-based charging is called electric car supply equipment (EVSE) or an adapter that includes the charging plug and cable which is sometimes referred to as an “smart cable”. An EVSE with a Level 1/2 rating isn’t an EV charger, however they’re referred to that way frequently. The charging standards call for digital communications between EV with the EVSE in order to negotiate the conditions of the charging session. The EV is in command of the charging process, the EVSE can monitor, connect and disengage the energy source, and also communicate with the EV via it is a “smart cable” (even even though there’s nearly always an electronic box or module that functions as a cord and charger). During the charging process it is necessary that the EVSE charger is secured inside it’s EV charging port, and the EV is locked in “Park” to ensure security. Other times the power is cut off from the EVSE plug to ensure that it is safe to handle. With the incredibly powerful power requirements of EV charging (up to 250kW, 625 amps at 400Vdc) this is a remarkablely secure system.

Complex, powerful “Level 3” dc EV charging stations are equipped with advanced electric vehicle charger circuitry because they are directly connected to the BEV’s dc battery pack for the highest power transfer. The charging station’s interconnection cable/plug is considered EVSE and is compliant in accordance with EVSE charging standards. Additionally, the EV remains in complete charge of every charging session.
