Esarj Electric vehicle charging station
Esarj electric vehicle normal charging station line has been developed and designed for conductive battery charging of the electric vehicle or plug-in hybrid electric vehicles on board batteries at public access charging spots.
It’s also usual to call it as Slow Chargers, but that name comes only as opposed to the Quick Chargers performances. The Normal Charge is when the power and voltage are the ones available in a household or any low voltage installation. For an ordinary electric vehicle, it is usually enough to fully recharge the electric vehicle battery from minimum to maximum in a time, that depending on the electric vehicle, is usually less than 8 hours. At private places any Esarj Home Charger model from our product line can replace a Normal Charger. It has similar charging rates of a single phase Normal Charger but with reduced management features. Eşarj electric vehicle charging station is compliant with EN/IEC 61851 and has CE mark, meeting the European and Turkish Directives for safety and EMC requirements. For better understanding of electric vehicle Charging modes please consult the EN/IEC 61851-1 related section. The Eşarj electric vehicle Normal Charger was primarily designed and developed as Mode 2, for 1st phase. Currently it has been upgraded to mode 3 operations. The Eşarj electric vehicle charging station performing in Mode 3, Case C has attached an output power cord. At standby the power cord plug is coupled to a socket in the charger bay. There is no locking door and the plug is free to be removed. The charger has a color warning light, which shows its own operation status. An alternative design in Mode 3 operation is the use of an output socket replacing the attached power cord. The plugs or sockets are available with the J1772 or the Mennekes format. Each Eşarj electric vehicle charging station is integrated in the Charging Infrastructure Network and the Central Management System controls its operation and status. If a charger is offline, user can still operate it although some functions cannot be accessible. Even in a power shutdown, emergency will release electric vehicle’s charging cord only to the identified user. Each user has its own Eşarj Membership Card that allows him to use the public charging infrastructure anywhere. By default, the contactless card data model is the Calypso standard but other standards can be adopted. The architecture of Eşarj electric vehicle charging station is highly scalable because single Central Command Unit controls the operation of up to 254 Power Satellite sockets. In the most usual design, each Power Satellite can hold up two independent outputs. Versions with different number can be built to meet customer needs. Charger Architecture Normal Charger was designed to have one Central Command Unit and the required number of Power Satellites, up to 254 sockets. This design option assures:
At each charging spot, there is a Power Satellite with wired data communication to the Central Command Unit and holding usually two independent outputs. User is warned about the electric vehicle charging status with the Satellite warning lights. The code colors Green, Blue, Orange and Red stands for Standby, Charging, Failure and Charge Ended. The Central Command Unit processes and controls system management data and the Satellite Unit controls the power related. The system has the following features:
