THE AMP Energy management unit

AMP’s Energy Management Unit, ampEMU, is a combination 
of a DC-DC, On-Board Charger (OBC), and Power 
Distribution Unit (PDU), with fast charge capabilities (500A), all-in-one.

This energy management system for EVs complies with the North American Charging Standard (NACS) by Tesla, Combined Charging System (CCS), and CHAdeMO. It is a combined energy management solution having the entire AMP EMS, the Energy Management System developed by AMP, embedded in it.

ampEMU utilizes the latest SiC technology from Wolfspeed to drastically reduce the power electronics packaging volume. This extremely compact unit will save space and reduce the vehicle’s overall weight, improving range.

Experience performance and efficiency like never before with ampEMU, the complete energy management system for electric vehicle applications.

1/3 Size of M3/MY Equivalent
The small size of ampEMU makes it convenient to install, which decreases the overall size of the vehicle's sub-system. As a result, the weight of the vehicle is reduced, which in turn increases its range.

Connected Cloud Analytics
When combined with our cloud-based ampLOGIC system, this unit offers data analysis capabilities that can be used to prevent vehicle degradation and optimize performance..

ASIL C Safety Rated
ampEMU is rated ASIL C for safety, and is highly resilient with exceptional fault tolerance and redundancy.

HVIL Protection
The high voltage interlock loop protection feature safeguards against the risks of electric shock and fire, while also ensuring compliance with safety standards and protecting the EV battery.

Answered by AMP Experts

ampEMU is an integrated solution that combines a DC-DC convertor, onboard charger (OBC), power distribution unit (PDU), and charge controller for electric vehicles all in one. It is a combined solution that is equivalent to a complete energy management system for passenger, commercial, and heavy-duty vehicles.

ampEMU, the Energy Management Unit by AMP, integrates different components in one unit that comes with various benefits:

  • Small packaging reduces overall weight and space utilization
  • Easy and unified software management
  • System level integration
  • Fewer harnesses
  • Cost Savings

Generation 1 of ampEMU, called ampEMU 400, can be deployed in all passenger and commercial vehicles using a 400 V battery architecture.

AMP will be enabling 800 V battery architecture vehicles as well with Generation 2 of ampEMU, ready to be deployed by Q2 2024. It will be compatible with various types of e-mobility applications like marine, and heavy-duty commercial, construction, and agricultural vehicles like trucks, buses, excavators, tractors, and more.

Generation 1 of ampEMU is completely off the shelf and is ready to be deployed for all electric vehicle applications. Generation 2 is currently under development that will be available by Q2 2024.

ampEMU 400 – Generation 1 of AMP Energy Management Unit combines DC DC, OBC, PDU (optional and customizable), and EVCC, with DC fast charging capabilities for a 400 V battery architecture.

ampEMU 800 – Generation 2 of AMP Energy Management Unit combines the generation 1 ampEMU capabilities with a BMS, powering 800 V battery architecture and enabling bi-directional charging (V2G).

The default PDU has 6 high voltage ports – 3 for low current and 3 for high current. However, the PDU can be customized and tailor-made as per project requirements.

ampEMU supports CCS1, CCS2, NACS, CHAdeMO, and ChaoJi charging standards. Furthermore, it supports all charging types – Level 1, Level 2, and Level 3, single phase and 3 Phase AC and DC fast charging.

No. The unit is developed to provide maximum power density in a smaller unit ensuring maximum efficiency and performance.
