  1. Calculatoare Incorporate – Curs11 ARM/MIPS EV Tendinte EV Avantaje Concepte esentiale New Beetle Electric Lab11 – Control Motor EV

  2. Automotive – 200x

  3. Pretul miscarii

  4. Automotive 201x

  5. De ce Electric Vehicle • Epuizarea resurselor bazate pe petrol • Poluare • Costuri ridicate • Existenta rezultate stiintifice aplicabile pentru: - motoare cu randament mare - baterii performante, - sisteme alimentare/incarcare, - computere pentru obtinere regimuri, functionare stabile si eficiente.

  6. Avantaje • Emisii poluante chimice - zero . Energia pentru incarcare poate fi generata in tehnologie green • Poluare fonica - zero . Aproape nu se aud in mers. • Eficiente - 85% din electricitatea consumata poate fi convertita in miscare. Vehicolele clasice au randament de max. 15-20%. • Costuri deplasare - costul “combustibilului” este de 15% din cel al benzinei . Benzina se va scumpi ! • Independenta - electricitatea necesara incarcarii bateriilor poate fi realizata acasa.

  7. Dezavantaje • Autonomie scazuta - cu un “plin” se parcurge 80-100 Km ( baterii LiIon) – nerocomandate pentru trasee lungi. ( Cu baterii recente – scumpe insa- se pot parcurge aprox. 300-400km) • Costuri mari pentru motor, controller si baterii. Exp: motor 2-4000$, controller 1500$, baterii 1-30 000 $; • Timpi mari alimentare – 2-6 ore incarcare baterii, • In viitor - scaderea preturilor pt. productia de masa , - dezvoltarea reteleor de PECO electric EXCELENT PENTRU URBAN VEHICLE!

  8. Solutie : conversie clasic-electric

  18. Baterii posibile 1. Li-Polymer battery. While still quite rare if scaled up to usable in EV size and up front expensive, at least it became available. Treated right, can be less expensive in a long run than lead acid batteries. Require sophisticated BMS (battery management system). 2. Li-Ion battery. Not as expensive and LiP battery above, but the next best thing. Technical requirements are the same as for LiP battery. Advantages (to me) are worth trying these. Require sophisticated BMS (battery management system). 3. NiNaCl Zebra battery. Expensive, looks like sold to OEM only, and limited selection (well matched to AC system requirements though). 4. NiZn battery - relatively new player on the market - comparable to NiMH and NiCd and (recently became) far less expensive. 5. NiMH battery. Not available for non-technical reasons and may never be available to you and to me. 6. NiCd battery. Realistically available from SAFT (France) or its subdivision ALCAD (Sweden). Expensive up front, but cheap over its long life time. 7.  PbA Gel Cell battery - quite a few choices. 8. PbA AGM sealed deep cycle battery - quite a few choices9. PbA flooded battery - many choices.

  19. Controller/invertor The power inverter. Manufacturer - Siemens AGCost - $3,800 iAvailable from Metric Mind Engineering The power AC inverter is the main part of the electrical system of the car, and its role is simple - to convert the battery energy to the form useable for the AC motor, and to deliver right amount of this energy per driver's demand. While it doesn't sound too complicated, to perform this task flawlessly the electronics gets quite complex, and it is especially true for AC drive systems. Functions: - Convert (invert) the DC battery voltage to the 3 phase AC voltage;- Adjust AC voltage amplitude and frequency based on the drive current demand and instant conditions like RPM and torque- Provide regenerative braking turning the traction motor into a generator for recuperating kinetic energy back to the battery pack; so it has to convert generated 3 phase AC voltage back to DC before feeding the batteries,
