Info
We are Deefholt Dynamics, the racing team of the PHWT in Diepholz, and we have been members of the Formula Student Community since 2006. What sets us apart is the fact that every year a brand new team designs and builds our race car from scratch in just six months. This season, 49 motivated students have come together with the common goal of developing a competitive race car, progressing step by step with unrivaled speed and determination. A key innovation: switching from 13- to 10-inch wheels.

We are Deefholt Dynamics, the racing team of the PHWT from Diepholz. We've been part of the FS-Community since 2006. The special thing about us: our car is built by a first-year team within only six months, every year. This season, 54 students joined the project with one goal: To build a competitive car one step at a time as fast as no one else can. Year after year. Among other things, we designed and build a new aerodynamic package and reduced the weight of our car.

Info
The formula student team of the UAS Diepholz – Deefholt Dynamics – is an interdisciplinary engineering team of 48 people. The race car is designed and manufactured in 6 - 7 months with a limited budget. A major challenge is the university’s requirement of a comparably low voltage of 120 V. This year’s car – PHWT-10e – has major changes compared to its predecessor.

Info
Fadeless and dynamic. This is Deefholt Dynamics from Northern Germany. Since 2010 our team has participated in the Formula Student Electric. Every year, we are eager to build a progressive car. With a new motor and an active cooling concept, our car is focused on endurance. 41 students with competences in mechatronics, electrical and mechanical engineering have worked on the FHWT-06e to optimize the performance and agility. Based on weight reduction we changed to 10 inch wheels. The connection between the tires and the frame is a double wishbone suspension. The new motor offers us higher performance and better efficiency, but also requires higher voltage. We have two accumulator containers with 200 cells in total, which deliver a voltage of 370V. In order to establish a modular and reliable system, the components are connected via CAN bus. A wireless connection allows the team to monitor the vehicle status, keep track of important parameters and help optimize future designs.

Info
Deefholt goes dynamic isn’t just a slogan, it’s an attitude! Starting the 5th time for the competition and the 3rd time with an electric car, we are proud of our achievements, but not willing to relax. Our team in 2012 consists of 32 students bringing in all their competences from mechanical, electrical, industrial engineering and mechatronics. The aim: Another weight reduction. In comparison to the former frame we achieved a reduction of 4.5 kilograms. In addition, the BMS is 5 kilograms lighter, although we even added new functions. Every year we create something new. In 2012 we will start with a self-developed drive control unit, which isn’t just smaller and lighter, but fulfills all the functions we need. It will control the two new DC motors with an actual power output of 18 kW per motor and a nominal torque of 42 Nm. Two planetary gears transmit the power directly to our new rims with self-developed wheel hub and central locking. We are looking forward to the event!

Info
Dynamically is how we’ll start; with new energy and a new team-name at the FSE-Event. Our Deefholt Dynamics Team (formerly: FHWT Racing Team) consists of 42 students from mechanical, mechatronic, electrical and industrial engineering. It is our goal to build an electric car that weighs less than 300kg and accelerates from 0km/h to 80km/h within 4 seconds. The race car is based on a tubular frame made of 25CrMo4 steel. The wheel carriers are milled aluminium parts and the wishbones are carbon tubes with aluminium fittings. The rear-wheel drive is powered by two DC motors, which activate the drive mechanism with a chain drive system. The race car’s energy source consists of 28 LiPo cells, located behind the driver’s seat. We are proud of our self-developed battery management system which measures the voltage of every cell, the temperature of every second cell and supplies the driver with information about BMS failures and critical cell conditions.

Info
The FHWT Racing Team is proud to present its new electric FHWT-03e-Racer. This electric FHWT-03e-Racer, based on its predecessor, the combustion engine FHWT-02, is totally in keeping with modern energy concepts. This year's team motto is to create a new driving experience, to revolutionize the driving characteristics like acceleration and cruising range while reducing environmental pollution. In addition, the two technical highlights, the water-cooled electric motor and the frequency converter, both in-house student developments, contribute towards achieving this ambitious goal. The motor is characterized by its ideal construction form, low weight, best possible power adjustment and high efficiency as is found in comparable electric motors. Moreover, the water-cooled frequency converter is, due to the light-weight compact construction, unique in its performance category. This year, an unprecedented 37 students from all FHWT-faculties are united for one reason - to score at Hockenheim.
