HV BATTERY SIMULATOR · MBS-01C
Real battery diagnostics.
In a safe environment.
A physical human-in-the-loop platform for HV battery measurement, fault finding and service procedures — designed to reproduce the workflow of a real traction battery without relying on a live vehicle battery.
SYSTEM SPECIFICATION
Built around the way an HV battery is actually measured.
The simulator combines a physical battery pack, removable components, real probing points and a software-controlled model. Parameters and fault conditions can be changed from the head unit, while the user performs the diagnosis on the hardware.
Configurable battery behaviour
Set manufacturer profile, cell type, cell capacity and state of charge from the integrated interface.
Fault injection
Introduce predefined fault conditions and diagnose their effect using physical measurements and system data.
Service procedures
Work down to cell and module level with removable busbars, modules, service plug and accessible HV connection points.
Digital diagnostics
Use serial diagnostics, charging mode, system feedback and optional augmented-reality functions alongside conventional measurements.
TECHNICAL DATA
Realistic hardware. Controlled risk. Enough variation for repeatable diagnostics.

- Measurements: V, mΩ, Ω, MΩ and A; 120–490 V measurable battery-pack range
- Manufacturer, cell type, SoC and capacity are configurable
- Six selectable cell types: Li-Mn, Li-Al, LiFePO, LiTi, LiNMC and NiMH
- DTC and parameter data change with the selected fault setup
- Cyclic single-cell charger simulation with revitalisation workflow
Safe
- Less than 10 mA fault current in an accidental-touch condition
- No electrochemical energy storage or hazardous battery chemicals
- Warnings for dangerous measurements and incorrect handling
- Suitable for secondary, higher-education and professional training
- AR functions, classroom use and safe transport are supported
- 100–250 VAC, 50/60 Hz mains operation for international deployment
Effective
- 20 selectable faults, from cell faults and interruptions to insulation faults
- Approximately 99 million different measurement iterations
- 10,000 different fault-finding scenarios in exam mode
- Screen mirroring to a projector or TV for group training
- No external measuring equipment required; upkeep is minimal
- Package: battery pack, head unit, two measuring leads/cables, power supply and documentation
ONE SYSTEM · MULTIPLE WORKFLOWS
The hardware and software stay in the same diagnostic loop.
The head unit controls the simulated battery state while the measurements are performed on the physical pack. This keeps the interaction close to workshop practice: change a condition, probe the system, read the response, isolate the cause.
LIVE-WORKING METHODOLOGY
Practise the procedure without connecting to a real traction battery.
The aim is not to make HV work casual. It is to let the same safety sequence be repeated, observed and corrected before technicians face a real battery.

Insulate and control
Rehearse temporary insulation and controlled live-working steps before carrying out the same methodology on real systems.

Diagnose
Trace faults with voltage, resistance, insulation and current measurements.

Disassemble
Practise module-level access and component identification on physical hardware.
EQUIPPED LABS
Integrated into complete NEV lab solutions.
The HV Battery Simulator can be supplied as part of a complete NEV lab solution designed and delivered by Maróti, including the surrounding workstations, safety equipment and complementary EV/HV training systems.


AUGMENTED REALITY
Put the diagnostic information directly onto the battery.
Using an AR-capable Android phone or tablet, the simulator can place digital information over the physical battery pack. This keeps the user looking at the component being examined rather than switching constantly between the hardware and a separate reference screen.
Identify modules, connectors, contactors and other parts directly in the camera view.
Visualise simulated thermal behaviour and relate temperature differences to the physical pack.
Bring electrical wiring information into the same working context while tracing a circuit.

PRODUCT + SUPPORT
Designed to be useful.
The hardware is only one part of the system. We support commissioning, product use and technical questions from our Budapest engineering and training operation.
- 01English manual
A detailed English manual covers setup, measurements, servicing procedures, fault-finding scenarios and troubleshooting.
- 02Worldwide power compatibility
Operates from 100–250 VAC, 50/60 Hz mains. The standard mains inlet supports country-specific plug leads for international installations.
ABOUT MARÓTI
Supporting automotive professionals and education since 1991.
Maróti Kft. was established in Budapest in 1991 as a publisher of automotive technical books and distributor of technical databases. From 2017, the company expanded into automotive educational equipment, course material and training-centre activities.
The HV Battery Simulator grew out of a practical requirement: provide realistic battery diagnostics and service work in an environment where the instructor can reproduce the same technical condition repeatedly. Development combines automotive engineering, software, diagnostic practice and feedback from HV professionals.

THEY SAID ABOUT US
Feedback from technical education.
Selected comments from educators and vocational-training leaders who reviewed the simulator concept and its use in practice.
You found a very innovative solution. I especially like how augmented reality is used on the simulator — the border between explanation and the physical system becomes much smaller.
The HV battery simulator is modern and practical. It gives teachers a way to demonstrate battery work without exposing students to the same hazards as a live traction battery.
With this simulator we can prepare HV technicians for a labour market where these skills are increasingly important.
