HIDRIA Inštitut za materiale in tehnologijo d.o.o. (Hidria Institute for
Materials and Technologies)
◦ Iskra Avtoelektrika is a global supplier of starter motors and generators for internal
combustion engines, electric motors and electrical drive and mechatronic systems for
working machinery, means of transport and use of the renewable sources of energy.
◦ Within the Hidria Corporation, the manufacturing programme of Hidria Rotomatika is
located in the industrial pillar with an emphasis on automotive technologies, more
precisely steering and drive train systems. The main products are die-cast aluminium
components and electrostatic sheet metal and steel components.
◦ The Institute represents the main R&D basis for Hidria Rotomatika in the field of
automotive technologies.

Hidria AET d.o.o.

Razvojno tehnološki center za vžigne sisteme in elektroniko d.o.o.
◦ Important producer of innovative systems for diesel cold start, fuel heaters and
mechatronics parts for diesel engines generation up to EURO 6 and beyond.
◦ Supports mother company Hidria AET with research, development and validation
activities.

Global chalenges – EU policy:

Expected development direction of these products: introduction of
high system voltage, high output power, speed and output torque.

Requirements: high fill factors above 70%, high efficiency above
95% and high specific power, for electrical motors 2kW/kg and for
electronic controller over 10kW/liter

Solutions must provide high IP protection and EMC compatibility.
◦ 20% increase of energy efficiency
◦ (Anticipated 10% increase in the use of el. and hybrid drive systems
by 2020)
◦ 20% renewable energy share by 2020
◦ 20% reduction in greenhouse gases (CO2, HC, NOx, Particulate
matter-PM)
Cold start system for diesel engine
1.
◦
System for cold start for diesel engines including glow plug with pressure sensor
either with metal or ceramics heater is assembled into diesel engine on the
vehicle with corresponding control unit. Pressure sensor in the glow plug enable
in-time control of combustion parameters in the cylinder and consequently
achieving optimal conditions which lead to lower fuel consumption and lower
emissions (NOx).
Electric machines - motor generators
2.
◦
Studies and practical solutions for contactless electrical machines with inserted
rare earth permanent magnets, induction generators, motors and alternators for
hybrid and electric vehicles with system voltages from 12V up to 500V. The
motor generators range from 2 kW to 50 kW of output power. The systems have
integrated or separately installed control electronics. The studies also consider
the advantages and disadvantages of direct drive inwheel electric motors to
drive vehicles . With partners on this project a new vital parts such as stator and
rotor laminated stacks were developed and have a defined production process
with some real tooling trial run.
Electronic controllers

5.
◦
A group of controllers or more precisely motor inverters of different voltage
levels (24 VDC ÷ 80 VDC or 600 VDC) for different powers (of a few kW to tens
of kW) intended for driving AC induction motors or synchronous IPM (Inserted
Permanent Magnets) BLPM (brushless) electric motors. The controllers are
designed primarily for the use on hybrid and electric vehicles or vessels and
they all support the four-quadrant mode of operation: in a suitable system with
an electric motor/generator they allow energy recovery during braking of the
vehicle or charging of the batteries while driving with internal combustion
engines on vessels.
BAS (Belt Alternator Starter)
The BAS (Belt Alternator Starter) Start–Stop system was developed. Final tests
showed that the BAS Start–Stop system is capable of cranking the ICE (Internal
Combustion Engine) and a stable operation in generator operation mode. Tests
also confirmed that the ECU (Electronic Control Unit) aluminium housing is
providing the sufficient cooling for controlers internal components.
Transmission, Cooling System end Electric Energy Storage Studies
Studies of Transmission, Cooling System end Electric Energy Storage provide
the basic guidelines for a successful development and the design solutions for
the integration of electrical machines and ECU's in electric and hybrid driving
systems.
Glow plug with integrated pressure sensor
Connector
Power line to the heater and
feedback signal line from
pressure sensor.
ASIC – Electronic circuit enable
processing of signal from
pressure sensor and send
analog signal to engine control
unit
Pressure sensor is integrated
into glow plug body and
detects pressure forces and
transform them into electrical
signal which ASICS can read
Metal heater
Hidria AET
Ceramic
heater
Innovative glow plug with piezo type of pressure sensor which significantly differs from
existing solutions on the marked. Total system, heater and closed-loop control of
combustion are critical factors to reduce fuel consumption and emissions of diesel engine.
Market interest (important producers of diesel engines) for this system is enormous, so
ambitious plans of Hidria AET to became one of 3 leading players in this segment is real.
Heater function is to glow and
consequently causes burning
process of the fuel. It could be
metal or ceramics type.
