An electric vehicle charging station, also called EV charging station, electric recharging point, charging point, charge point, electronic charging station (ECS), and electric vehicle supply equipment (EVSE), is a machine that supplies electric energy for the recharging of plug-in electric vehicles—including electric cars, neighborhood electric vehicles, and plug-in hybrids.

1. Electric Vehicle charging System
EV charging systems are one of the requirements for the wider adoption of
EVs. Fast charging systems and their associated products and solutions
are becoming an active field of development at many companies. There is
also a need to put in place the charging infrastructure required for wider
use of EVs in the future. Meanwhile, issues that are still to be resolved
include network management of charging units installed by various
operators around the world and the construction of systems for charging
unit user identification, billing, and payment.
Our Solution:
EV charging solution has been developed in response to these
requirements. The solution includes the development of a charging unit
based on power electronics technology as well as the management and
operation of charging units based on control and information technology
and a charging unit management solution that provides user services. Our
EV charging systems include charging networks such as DBT, Charge
Point, and ECOtality. These EV charging networks focus on providing EV
chargers with the ability to identify users and take payments for public
charging. The system is neutral about the hardware, the control center and
network that interconnect it with all the parts of the system.

2. Features of the Solution:
• A comprehensive set of basic functions for charging unit management
• System is independent of charging unit supplier
• Service platform is designed for operational efficiency
• Integration with existing commercial systems
• Integration and expandability for creating the next generation of smart
cities.
Challenges and its Solutions:
Beyond the critical requirements to keep the power usage within the safety
requirements dictated by the local circuits, this EV charging system is
neutral concerning the actual charge scheduling. Any relevant information
can be used to influence any relevant type of algorithm to schedule the
charging. Charge scheduling could be influenced by user demands, power
prices, and grid requirements in the form of price or DR signals,
consumption or the availability of alternative energy resources. Highly
developed algorithms may use the forecasting of all the above conditions to
take the charge scheduling to another level. Therefore the scheduling
algorithms will be constrained by available resources such as computing
power, bandwidth capacity, and data availability.
Benefits of the Solution:
• In the current system, the server not only keeps a database of account
holders to allow login in and charging, but tracks their usage such as
connect time, leave time, amount of power used, whether the EV was fully
charged, and the amount of current the EV used over time.
• The EVSEs allows multiple EVs to share a single circuit and available grid
capacity.
• The control system is both network and hardware neutral and can connect
to other devices and systems through the internet for data gathering and
information exchange.
