SustEner - Teaching Energy for Sustainable World

The project SustEner is a part of the EU Lifelong Learning Programme “Leonardo da Vinci”. Its aim is to modernize vocational training on Sustainable Electrical Energy by enhancing existing or establishing new training methods in enterprises and education. A number of high quality learning modules delivering knowledge are going to be prepared to enhance and modernize vocational training and distance learning by incorporation of advanced learning methods such as interactive animations or distance laboratories.

E-DeMa – The Basis For Market Economy Incentives During Electricity Consumption

A general differentiation is made between those people who generate electricity and those who use it, the customers. E-DeMa does not use the word customer; it is replaced by „Prosumer". This is taken to mean the active customer who both generates electricity and feeds it into the grid (producer) and uses this electricity (consumer). This is one of the most important goals of the project: the encouragement of the end consumer's active involvement and participation in the energy market. The E-Energy Marketplace 2020 to be established within the scope of the project is based on the distribution grid of RWE Deutschland AG; the model regions Mülheim and Krefeld are part of this distribution grid. A key aim is to integrate „Prosumers" by means of IKT gateways which enable both the load management and control of household devices, smart metering as well as the control of local feeders. The benefits are manifold: displayed energy consumptions or price signals for the prosumer, online information for an improved grid management by the network operator. E-DeMa creates an integral infrastructure to control the consumption with an active involvement of the consumer and on the basis of which further energy services can be established.

Suitability for daily use of electromobility - Elements for a technology roadmap: Infrastructure - Vehicle - Safety

In this project, several electric vehicles and their components were examined with regard to the suitability for daily use. The vehicles were equipped with high resolution measurement devices and they were given to 70 test drivers with different user profiles in a field test. As a result, specifications, parameters and criteria for prospective required vehicle parts and characteristics were investigated.

BMS - Bat­te­rie Ma­nage­ment Sys­tem

A broad range of products includes a battery supply. Driving in winter with a car that contains an aged lead acid battery might end in breakdown. Before switching off the engine there is a need to know whether it is likely to restart at the next attempt. This necessitates a system that is able to display the battery status. This system is called a Battery Management System (BMS). To estimate battery status, complicated models are necessary. Usually these models need between 10 to 15 diverse parameters with various values. Aiming at the problem of parameter inquiry, this paper presents a simplified model with three parameters, including a comprehensible delineation for determining the parameters. This model allows the continuous determination of the State of Charge (SoC), including the Depth of Discharge (DoD), the State of Function (SoF), and the State of Health (SoH) by measuring the current, voltage, and temperature of the battery system. Because it decreases the arithmetic expenditure the BMS is integrable in feeble microcontroller units. This allows highly flexible integration, whereby the loss of accuracy is negligible due to parameter adaption. Standard systems suffer from large number of parameters and a long offline calibration time for each individual battery. In contrast, the BMS is able to relinquish any offline calibration, if and when required. A smart observer strategy allows the BMS to be ecalibrated within a few days in an normal used car. Besides the car’s battery, systems in forklifts and other vehicles as well as other processes are able to be monitored and controlled with this BMS. Because it is based on the chemical behavior of a lead acid battery, the BMS is adaptable to other chemical processes. This provides the option of implementing the BMS for traction batteries in Electric Vehicles (EV).
