INTEMAS

INTEMAS focuses on optimizing the design and control of electric and hybrid drives for vehicles and machines. The project aims to support companies in scientifically based design of the energy management system (EMS) and a proposal for the dimensioning of the subsystems (battery, combustion engine, etc.).INTEMAS also lays the link to the non-automotive sector: transport equipment in the agricultural sector.

Background

After a thorough analysis of market requirements through bilateral discussions and a workshop, HAN Automotive Research (HAN AR) identified that the industry requires support in optimizing the design and control of the electric and hybrid drives for their (prototype) vehicles and machines.

The complexity of requirements, pre-conditions and technical possibilities are difficult to oversee and translate to a successful product that meets the needs of the customer. The INTEMAS project aims to support these companies in this important task, by providing a sufficiently detailed analysis, with a scientific design of the energy management system (EMS) and a proposal for the dimensioning of the subsystems. (battery, combustion engine, etc.). The EMS is a system that constantly chooses the most optimal operating point for the various energy systems on board the vehicle. This choice is determined on the basis of requirements and wishes in terms of, among others, emissions, energy consumption, performance and/or costs.

HAN wants to combine its own knowledge and experience with those of various companies and the control technology group of the Hochschule Rhein Waal to come up with new insights and solutions.

Final Outcomes

Much knowledge and experience at HAN AR (control technology, model development, safety concepts, test techniques) has been gained with the automotive industry. With INTEMAS we want to expand our field of activity towards the Agro industry, an industry with a lot of potential because of its size and state of the art. Cross-fertilization between the two domains can lead to great benefits with relatively little effort.

Important deliverables of the INTEMAS project are TCO analysis of various products, a software tool for dimensioning of subsystems, EMS report in practical applications and at least 2 demonstrators (electric bicycle and a hybrid tractor). Building the demonstrators is not part of the INTEMAS project; this will be done by the partner companies.

Current Status

Electric and hybrid vehicles play an important role in government policies to reduce CO2 emissions from transport to improve air quality. INTEMAS is for companies that are looking to achieve:

1. Lower levels of pollution, less CO2 expel (emissions).
2. Ensuring better battery performance and greater range.
3. A competitive cost factor.

A few accomplishments of this project are:

1. Intelligent electric bicycles: One of the objectives relates to power assist control. We have designed an EMS that calculates the optimum support based on route characteristics, such as length of route, slope or wind speed during the route and the available energy from the battery. In the other objective, the EMS optimizes the electric assistance with respect to the heart rate of the cyclist.

2. EMS for agricultural vehicles: This is one of the new applications where an EMS is designed based on the route information of agricultural vehicles that is translated into power demand patterns.
INTEMAS enables the development of application specific Energy Management Systems (EMS) for a wide range of vehicles and agricultural equipment.
