The Necessity of Fast
Charging
Power supply is an important topic of urban
traffic. The existing power system in the city is
mainly for providing power to residences, office
buildings, and for lighting in the city. Now, with
the rise of EV’s, the power supply system must
provide extra power. A densely populated city
where 70~80% of the power is being consumed,
means only about 20% is available for charging
EV’s. Assuming a community consumes about
4MKVA and if only 20% (800KW) is available for
fast charging, after simple calculation the power
is apparently not enough for the community to
charge 4 electric vehicles simultaneously.
The Self-sufficient
Research, Development
and Design of The Core
of Charger Controls
CSU 3.0, the core controller of electric
vehicle chargers researched, developed, and
designed by Phihong Technology, uses highly
efficient MPU and multi-threading scheduling
to execute the control and monitoring of the
electric vehicle chargers. It is mainly used in
DC fast chargers and high-end commercial AC
chargers. There are 6 main functions:
In order to respond to the booming trend of
electric vehicle and power grid system demand
worldwide, Phihong Technology a leading global
supplier of OEM power solutions, with close
to 50 years of professional power supply and
production technology, provides multiple electric
vehicle charging solutions and is dedicated to
realizing the future of green energy through even
smarter and ecological electric vehicle charging
solutions.

Process Control of The Charger
CSU3.0 has many standard communication and
control interfaces that control, monitor, and protect
various functional modules inside the charger.
