3. Critical components for EV Charging
ON-BOARD CHARGING- THE OBC
CHARGES THE BATTERIES IN AN
HEV/EV BY CONNECTING THE VEHICLE
TO THE GRID.
THE GRID IS AC (ALTERNATING
CURRENT) AND THE BATTERY IS DC,
THEREFORE THE CHARGER IS AN
AC/DC SYSTEM.
THE CHARGER IS BUILT INTO THE
VEHICLE AND THEREFORE CALLED
“ON-BOARD,” IT MUST BE AS SMALL
AND LIGHT AS POSSIBLE. ONE KEY
TREND CURRENTLY UNDER
DEVELOPMENT IS POWER (FROM THE
GRID TO CHARGE THE BATTERY IN THE
CAR) GREATER THAN 3.3KW (WHICH
HAS BEEN THE TRADITIONAL POWER
LEVEL) TO ENABLE FAST CHARGING.
FAST CHARGING IS A VITAL PROCESS
FOR HEVS/EVS TO COMPETE AGAINST
PETROL & DIESEL VEHICLES, WHICH
DRIVERS CAN FILL UP WITH FUEL IN
JUST A FEW MINUTES.

4. EV Powertrain
• Traditional system have 12V batteries & electronics
• HEV/EV architecture is high voltage. Modern EV vehicles are based on high-voltage battery systems, such
as +400V for EVs and 48V for HEVs.
• The basis for energy-efficiency improvements through high voltage will occur through the advancement
of switch-mode power supplies (SMPS) enabled by power electronics.
• SMPS in powertrain electrification SMPS conditioners are realised in these power train sub-systems in
HEVs/EVs.
AC/DC
• Regenerative braking.
• OBC
DC/DC dual-battery system
• Battery management for lithium-ion (Li-Ion) batteries
• 48V to 12V bidirectional power supplies
• 400V batteries (EVs only)
• Bidirectional 400V to 12V power supplies
DC/AC
• Traction motors
• Auxiliary inverters

5. Schurter provides Fuse and Choke solutions
essential for EV Charging & Battery management
systems
• Critical components are required for EV
Charging hardware.
• Thermal management, Safe operation
• AC and DC power conversion
• Galvanic Isolation
• Efficiency of charging circuits to deliver fast
charging
• Maintaining the management of battery
systems for the longest life possible.
• Voltage protection

7. AEC-Q200 Fuses

8. USN1206
The USN 1206 has been
developed as an SMD
temperature protection for
power semiconductors (e.g.,
MOS FETs) in automotive
applications. At the same time,
it also provides protection
against overcurrent. The USN
1206 from SCHURTER has high
I2t values (slow characteristic)
and a rated current of 12 A at
32 VDC. The fuse has a current-
time characteristic which shifts
as a function of the ambient
temperature. As a result, a
specific triggering at a certain
threshold value can be
achieved with increasing
temperature.

9. RTS
Thermally activated fuse
A Patented surface mount
thermal fuse to protect against
thermal runaway of power
semiconductors such as:
MOSFET's, IC's, IGBT's, Triac's,
SCR's, etc.
Highest reliability thanks to
complete galvanic Separation
Separates rated voltages up to
60 VDC - Reflow compatible
through mechanical activation
procedure –
Galvanic separation happens
inside the RTS housing
Space-saving thanks to
integrated shunt
