For the 2020 season, the team prepared a mechanically optimized version of the FSE.08 monopost. An all-carbon monocoque from the 2019 season was used for the new electric formula. The aeropacket was redesigned and the cooling of engines and power electronics was also completely redesigned. The battery cooling system also remained unchanged. All mechanical changes on the monopost promise higher reliability in the longest Endurance discipline.
The electronics of the formula have also undergone significant changes. The most significant shift is functional telemetry or rubber surface temperature measurement. All electronics were thoroughly overhauled and the electronics in the battery were completely redesigned.
In the 2020 season, the team constructed the historically first autonomous electric formula in the Czech Republic. The self-steering monopost was created using the mechanical design of the FSE.07 monopost, which, however, underwent a complete reconstruction from the electrical point of view. The newly formed group in the team had to deal with many new problems such as sensing and recognizing the surroundings, calculating the ideal distance, the steering itself or the emergency braking system.
Surrounding is detected by 3 stereo cameras together with LiDAR. The main computing unit of DV.01 became a small computer from NVIDIA. Inside this small unit is a surprisingly powerful unit capable of driving an entire car. Xavier contains a powerful graphics chip that is used to process data from cameras using neural networks (YOLO v3). The turning of the wheels is realized by means of a power steering located directly in the vertical steering rod, which is able to precisely control the direction of travel of the formula thanks to a set of sensors monitoring the current turning of the wheels. The change to commercial converters was also a big change.
For the 2019 season, the team has prepared a completely new monopost from a mechanical point of view. FSE.08 has a new monocoque, which allowed the installation of an optimized battery with even better cooling. This promises faster times in the longest Endurance discipline. The monocoque was further better aerodynamically optimized and provided space for a diffuser. Together with the new rear wing, the pressure balance has been improved. Of course, the pressure is increased again and the aerodynamic efficiency is improved. The wheel group and axles also underwent a big change. Undoubtedly, the biggest is the change of tires to the Hoosier brand and rims to magnesium OZ Racing.
The electric group focused on improving the telemetry associated with tuning traction control and adding accurate measurements of the inertial point of the monopost. All the control units were also miniaturized. Another major task was to increase the reliability of the wiring harnesses.
The seventh generation of the Formula One car was designed with an emphasis on reliability and improved driving performance. The requirements for the sixth generation changes were based on the results of the previous monopost tests. From the test data, we were able to improve the performance of the formula on the track.
Enhanced engines, battery and controls, along with altered composite full-moonlight, won a double win this year. This year, our team has moved our team closer to perfect understanding of our concepts.
The year 2016 has certainly shown the direction of the development of the only Czech electric formula. The concept, which includes a composite all-wheel drive, independent all-wheel drive and proprietary design electronics, has proven to be fully competitive, so FSE.06 will be developed with the emphasis on fine-tuning even the latest detail.
In this season, the emphasis is on simulating the driving characteristics of the monopost and the subsequent use to improve them. It will surely help to optimize a more efficient active air duplicator, overhauling drive components, and using axle stabilizers.
The experience gained in the field of composite structures also enables the final development of our own carbon 10 "rims.
After extensive changes to the fourth generation of the FSE, the new generation 5 will be built especially to optimize and increase reliability of innovations and systems of the previous monopost.
The akupack will undergo more significant changes, the higher capacity of which will allow it to take full advantage of the power of all four engines. After great success with parts made of carbon composites in the 2015 season, the design of the fifth generation of the monopost is also in play, as is the design of the monocoque.
More information on the design of the newest monopost will be published during the design. Definitely watch us!
The eForce FEE Prague Formula team decided to take a strenuous step after successfully entering the world of Formula Student. The new car for the 2015 season will not only rely on the electric drive system of the rear axle but also the front axle.
The all-new FSE.04x monopost will be equipped with four engines, which will move the car a huge step forward in terms of handling, especially in adverse adhesion conditions. The Aeropaket was modified according to the requirements of the new version of the rules for 2015. Completely redesigned frame, new electronic systems - this is only a fraction of the innovations that the FSE.04x monopost brings.
The 2014 seasonal carriage carries the order number three. The FSE.03 (Formula Student Electric) is a logical outcome of the next year of development that the eForce Prague Formula team will try to make use of in three racing companies of the Formula Student International competition.
FSE.03 is conceptually based on its predecessor FSE.02, with changes in the frame area that has been truncated. Other mechanical adjustments boast redesigned control and increased share of composite parts. It is precisely the carbon fiber that carries the most visible change, which is a complete active air repel, which ensures faster cornering and a higher stability of the car during braking.
The FSE.03 monopost was replaced by 30 students who brought the car into the world during the year of development. In the 2014 season, eForce Prague Formula is waiting for three racing businesses across Europe.
The FSE.02 is characterized by a high torque of a pair of motors, multi-arm suspensions with unequally long A-arms and custom-made electronics.
Weight savings have reached 52kg and reduced the weight of the entire car to 278kg. This progress has been achieved by the use of a large number of composite parts.
The FSE.02 monopost was replaced by 30 students who brought the car into the world during the year of development. In the 2013 season, the brand new race car took part in four Formula Student competition races.
FSE.02 participated in a total of four Formula Student races in the Czech Republic, Hungary, Austria and Italy.
The FSE.01 was the first ever Formula Electric Student in the Czech Republic.
The development was attended by 30 students of the Czech Technical University in Prague for almost two years. The development began with the creation of the team under the title of CTU CarTech in 2010. After two years of development, FSE.01 set off for the first time at 2012, where it convinced its reliability and performance, despite its higher weight of 330 kilograms.
Monopost has participated in two Formula Formula races in Hungary and Italy.
