The eVolve Master Slave is designed to reduce or eliminate the cost of infrastructure upgrades when multiple charging stations are installed in a location where the power supply is limited. A hard limit can be set on the master charging station which then load balances the power over the slave stations. For example, a hard limit of 50 kW is set on the master station. One car charging gets 22 kW. Ten cars charging get 5 kW each. The Master unit with EFTPOS Payment System controls the paid access of Slave Units.
Why Master- Slave
Available with EFTPOS Payment System
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
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.
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 connecor.
FEATURES & ADDITIONAL INFORMATION
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.
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.
BENEFITS FOR OPERATOR/OWNER
Lower installation, electrical connection, electrical usage, communication, operating, and hardware costs due to master and slave system. A single modem in the Master unit can be used for remote connection and back-office system integration (OCPP 1.5). Its frontal key-locked door provides an easy access to the inside of the charger.
BENEFITS FOR USER
Its touch-screen provides clear charging instructions and plug status, and also allows the user to select amongst several languages.
eVolve series include electrical protections to minimise the safety risk of electrical shock and ensure the maximum up time due to independent protections per connector.
