Communication of Cluster Using Can Bus

The paper deals with the communication between the infotainment elements and the drive component of the car using the CAN bus. In the introduction, there is briefly described the communication bus used in cars. It describes its basic features, benefits and utilization. The main task is graphically programmed and builds a dashboard that will resemble to a real dashboard from a Volkswagen Golf 5. Using the dashboard built in LabVIEW, it controls the real dashboard

Battery Charging Procedure Proposal Including Regeneration of Short-Circuited and Deeply Discharged LiFePO4 Traction Batteries

The presented paper discusses the most often damages applying for lithium traction and non-traction cells. The focus is therefore given on investigation of possibilities related to the recovery of such damaged lithium-ion batteries, more specifically after long-term short-circuit and deep discharge. For this purpose, initially, the short-circuit was applied to the selected type of traction LiFePO4 cell. Also, the deeply discharged cell was identified and observed. Both damaged cells would exhibit visible damage if electro-mechanical properties were measured. Individual types of damage require a different approach for battery regeneration to recover cells as much as possible. For this purpose, experimental set-up for automated system integrating proposed recovery methods were realized, while battery under test undergone a full-range of regeneration procedure. As a verification of the proposed regeneration algorithms, the test of delivered Ampere-hours (Ah) for various discharging currents was realized both for short-circuited as well as deeply discharged cells. Received results have been compared to the new/referenced cell, which undergoes the same test of delivered Ah. From the final evaluation is seen, that proposed procedure can recover damaged cell up to 80% of its full capacity if short-circuit was applied, or 70% if a deeply discharged cell is considered

Recovery Procedure for Deeply Discharged LiFePo4 Traction Battery

Presented paper deals with possibility of recovery of damaged traction batteries by deep discharge. For the test of proposed charging algorithm, new, unused cell was selected, the deeply discharged condition of which was caused by the self-discharge during the improper storage. The cell had significant damage of package in the central part. For the battery testing, experimental set-up was realized for automated recovering procedure and other tests of cells. For verification of the proposed algorithm, a recovered cell was compared to a reference/new cell by testing the delivered ampere-hours for various discharging current. The final evaluation shows that the proposed algorithm for recovery of the deeply discharged cell can recover up to 70% of the nominal cell capacity

Visualization of Skoda Instrument Cluster

Most signals in modern vehicles which are transmitted from sensors to control units or actuators are transmitted via bus. The most common automotive data bus is Controller Area Network(CAN). Some of transmitted signals are speed of the vehicle, engine speed and coolant temperature which are used for visualization of Skoda Octavia instrumental cluster. For this visualization, CAN BUS communication is filtered and processed, to obtain three message objects to observe required data. For data acquisition from bus is used modular system CompactRio with module for CAN BUS from National Instruments. The whole application is created in visual programming language LabVIEW using FPGA module
