Maróti - HV Battery Simulator

Solution

HV Battery Simulator Trainer

Repair Experience

Many of the major challenges an automotive professional facing with are related to diagnostics, maintenance and repair of HV batteries.

Training challenges

Organising a training day related to HV batteries in a safe environment is consideted an almost impossible task.

Solution

The industry needs an instrument to help them deliver high-level and yet ceompletely safe trainings related to HV batteries for their colleagues and customers.

Product

Specification and features

Background

The HV battery trainer has been developed by a handful of Hungarian automotive and software development engineers. Every main R&D phases was validated by experienced high voltage professionals (mechanics, electrical engineers). It took almost 3 years from the first prototype to the just-before-manufacturing alpha type.

The development team reached our main goal to create a realistic yet all around safe to use instrument which is ready to series production at the same time.

Realistic

The simulator resembles a real HV battery
Consists 60 modules arranged in 5 modules in series
Disassembleable up-to cell level
Measuring capabilities: V, mΩ, Ω, MΩ, A
Measurable pack voltages: 120-490 V
Settable cell-tpye, brand, SoC, capacity and more
Cyclic cell charger simulator
Easy to move, only 40 kgs

Safe

The HV battery simulator provides a modern and safe way to teach about HV batteries for every training centres and institutes. It is safe because:

Current is limited to 10 mA when accidentally touch
No electro-chemical energy storage
The system alarms if dangerous operation is detected
Safe to teach all generations, youths and adults
works from normal wall-plug

Accidents (electric shock, explosion) related to real HV batteries would never happen using our simulator during trainings.

Diagnostics

It is an extremely hard and dangerous task to set up faults in real HV batteries coming from a real car. Our HV battery simulator can easily simulate the most freqent faults.

19 different faults can be simulated from cell faults to insulation problems
99 million different measurement permutations can be executed
10 000 different exam task can be set up
DTCs and live data realted to specific fault and brand

e-Learning

E-Learning material has been developed simultaneously with the simulator in order to provide the same high-level yet bespoke experience to every student. The curriculum incorporates part identification, work-safety, repair procedures, measurement practices and diagnostics related to HV batteries. Since everyone has their own login account, the learning becomes a personal experience in one's own pace.

From September 2023 the full 20-hours e-Learning curriculum will be available in English and Hungarian. It can be translated into any language later. The simulator can be used in real life environment using real life PPE equipment. Thanks to the provided secondary display connector, it can be used for group trainings as well.

Augmented reality (AR)

Besides the e-Learing curriculum, the simulator has some extra features using augmented reality (AR). Using our personal login account, simply pointing our mobile device or tablet towards specific positions, we can access functions like:

thermal camera
identification plates, labels
auxilliary systems (eg. cooling system)

Support

We can provide the following supports to the simulator:

CE certificate
Updates and add-ons in curriculum and AR functionality
Updates on simulator software and firmware
Bespoke trainings for trainers and teachers in English and Hungarian

Prototypes

HV battery simulator

We have our own cutting-edge automotive training centre specialising on diagnostics, oscilloscope use and electric powertrain. Moving towards HV battery training was a self-understanding decision. Therefore, we faced all the hazards (electric shock, explosion) related to HV batteries.

Thus, we started to search for a available solution on the market which is realistic, safe and has settable faults. And last but not at least, has a competitive price.

We were not lucky, so we started to develop our own based on the forementioned principles.

Are you in the same position as we were? Contact us!

Kossuth Lajos Bilingual Vocational Secondary School Budapest

You had found a very innovative solution and I especially like how you are using augmented reality on the simulator. This way the border vanished between imagination and reality.

Miklós Horváth

Vas- es Villamosipari Vocational Secondary School Sopron

The HV battery simulator is quite modern and cutting-edge. From now, no teacher has to worry that their students get electrified or injured.

Dr Csaba Varga

chancellor (MSc, JD)
Budapest Region Vocational Training Centre

As the chancellor of all automotive vocational schools in Budapest, Hungary, and also as a certified helicopter pilot and operation engineer I have to say, that what you are doing is fantastic. With the help of this simulator we are able to deliver qualified HV technicians to the labour market who are right now in very high demand.

Damjanics János Vocational Secondary School Hatvan

The job of vocational technical teacher starts where the theoretical technical teachers' ends. It is gereat to see students when they find correlation between what they had learnt during the classes and the simulator. It is part of their learning experience. This waay, the students develop self-condidence and such systematic approach which they can use in the future as employees.

Csonka Janos Voscational Secondary School Budapest

Most of our students are coming from the Z and Y generations -- they were born into this digitalized world. The HV battery simulator performs well in all important aspects, e.g. realistic, energy efficient, safe-to-use. Further, it can be used for individual or group teaching and/or examing. We are eager for the oncoming e-Learning curriculum.
