Master Slave

Master-Slave is a multipoint charging system designed to minimize the initial investment (CAPEX) and the operating expenses (OPEX) when several chargers are required. This solution is a combination of a Master charger and a set of Slaves controlled by this Master. The whole system works as if all the chargers had smart capabilities.

Evolved e-Volve: Efficient, Easy and Effective

Application
Designed to minimize the initial investment (CAPEX) and the operating expenses (OPEX) when several chargers are required, this solution is a combination of a Master charger and a set of Slaves controlled by this Master. The whole system works as if all the chargers had smart capabilities. Suitable for private installations such as workfleets or communities with a unique administrator, but also suitable for public access environment such as shopping center, parking lots, airports and others.

Concept Design
It shares the external concept design with the acclaimed eVolve series, so beyond its modern lines and robust housing, harsh weather conditions and user-friendly operation have been considered.

Why Master- Slave

• Multi-point charging system: capable of supplying output power without being connected to a remote back office
• Permits distribution of power which is supplied to multiple users from single charger
• Master slave allows user and load management to be carried out either remotely though OCPP Management
• Reduction of Installation costs and optimization of Electrical energy cost derived from a new connection and to reduce the power that needs to be contracted
• Use of single modem for the whole system will decrease maintenance cost of connection lines
• Simpler hardware and optimized installation cost
• Touch screen with multilingual to improve user experience

For Charge Point Operator / Owner

• The Master charger is capable of balancing the available power based on the number of charge points in use, thus the total power required to provide the total load gets substantially reduced. This may represent a cost reduction in the electrical connection set up and a cost saving due to a minor energy contract.
• Also, by centralizing the smart capabilities into the Master, the hardware of the Slaves gets reduced, so combining Master-Slave is the best choice to minimize the hardware cost.
• A single modem in the Master unit can be used for remote connection and back-office system integration (by means of OCPP 1.5), so communication fees also get reduced avoiding extra OPEX cost.
• The Master can operate up to 8 Slaves (max. 18 charging points including the Master) managing the load and user authentication.
• For carparks without OCPP backend, standalone configuration offers load balancing feature and user control through RFID.
• Its frontal key-locked door provides an easy access to the inside of the charger which results in a lower OPEX (Operating Expenditure) due to a quicker installation and service (preventive/corrective). Moreover, it allows the charger to be installed next to a wall optimising the available space.

For Charge Point User

• Its 8’’ daylight readable touch-screen not only provides clear charging instructions (e.g. wrong EV shift position to start the charge) and plug status (e.g. reserved charge point) but also allows the user to select amongst several languages.
• To comply with the most demanding requirements regarding billing, eVolve series includes MID certified meters.
• eVolve series include the necessary electrical protections (optional) not only to minimize the human safety risk of electrical shock but also to ensure the maximum uptime due to independent protections per connector.
