The whirring of success as Formula E customer car completes test debut

Formula E’s new fully-electric race car, the Spark-Renault SRT_01E, has successfully completed its test debut at the La Ferté Gaucher circuit near Choisy-le-Roi, France.

Unveiled this year at the at the Frankfurt Motor Show, the new single-seater was driven by Lucas di Grassi who will be undertaking the early test and development work.

 

The car completed around 40 laps over two days with the initial task of checking all systems were functioning correctly. For the test, the car was fitted with a 50kw battery, a quarter of the maximum 200kw power (270bhp equivalent) the final car will produce.

The inaugural FIA Formula E Championship, the world’s first global electric race series, begins in September 2014.

  • A 50kW battery? A battery has a capacity, not a power. Or is this the maximum rate at which the battery can deliver power without overheating?

  • It's a 8kWh battery and the race battery will be 30kWh. I'm not sure where the kW figures are from, it might be Luca's comments at the end that are misleading the stories. The capacity != max current draw and I doubt they will increase linearly with each other.

  • This car is trying to look like a Formula One racing car. With this in mind, the average power used by this so-called 'racing' car would have to be something in the region of 175 bhp (about 150 kWs) during the race. This means its 30kWh battery would only last 12 minutes. I can't see racing car enthusiasts or sponsors paying money to watch a twelve-minute Grand Prix can you?

    This vehicle has no practical or commercial value whatsoever. It is merely a milk-cow devised by life-style enthusiasts to get the Government to pay for their hobby.

  • Check out the performance of electric class cars in the Formula Student competitions at Silverstone and Hockenheim this year. Students design and build these cars each year. A fantastic hands on, real life project for these young student engineers.

  • My thoughts same as above. the sentence:
    "For the test, the car was fitted with a 50kw battery, a quarter of the maximum 200kw power (270bhp equivalent) the final car will produce" is nonsense.

  • See below for a formal response from Formula E.

  • Excellent piece of kit, well done. Sounds all wrong though!

  • Hi all,

    We thought an official reply from Formula E might help clear this up. The battery all SRT_01E cars will use is 30kw but through various means it produces 200kw of power. So effectively the battery it tested with was an 8kw battery producing 50kw of power and therefore a quarter of the maximum power we will use.

    Hope that helps.

  • That official response doesn't make any more sense than the article. What's the battery's capacity in Wh? What's its maximum power delivery in W?
    What's the motor's maximum power?

  • Usually, the battery power (W) is the battery disharge capacity (Ah) multiplied by the nominal voltage. So, for example, a 2200mAh with 3.6V nominal voltage is said to have a 7.92W power.
