New mia electric city car uses Sevcon controller

5 July 2011

The three seat mia electric city car (earlier post) is powered by a Leroy Somer asynchronous motor which will be controlled by Sevcon’ Gen4 size 4 80V 350A motor control (earlier post).

The Mia, with 8 kWh battery packs from Evida, has a range of up to 130 km (81 miles) and is fully chargeable within 3 hours.

The size 4—one of four controllers in the Gen4 series ranging from size 2 to 8—was chosen to deliver smooth power transmission, improved efficiency and an extended range capability due to its ability to be closely characterized with the specific requirements of the mia.

Peugeot’s e-vivacity scooter, Vmoto’s E-max bike and Brammo’s Enertia street bike also use Sevcon Gen4 controllers. The mia will be manufactured in Cerizay, France, and has a scheduled annual production run of 12,000 vehicles a year.

Sales of the mia will initially focus on public and private fleet operators with sales to private customers starting in 2012.

Mia electric took over the electric cars divisions of French vehicle manufacturer Heuliez in July 2010. Heuliez has been designing and producing pure drive electric cars since 1984 and has manufactured more than 6,500 electric cars including Citroen AX Electric, Peugeot 106 Electric and Citroen Saxo Electric.

A range of 130 Km with a small 8 Kwh battery pack is very good efficiency. No ICE vehicle could do as much?.

Yea, I think there are some assumptions being made here, like only a single 8Kwh pack per vehicle. I don't think that's the case. 80 miles on 8 Kwh would make this vehicle over twice as efficient as the Tesla, which I do believe is currently the most efficient production car available, at around 250 Whr/mile. To expect this car which is admittedly 1000 lbs. lighter to get 100 Whr/mile seems unrealistic, that's what electric motorcycles do on average.

"The Evida 8 kWh lithium-iron-phosphate battery pack will provide the ultra-modern and light-weight vehicles with a range of between 80 and 90 km per charge in urban cycle"

That's 50-55 mile range.
Weighing in around the weight of the original Kübelsitzwagen,
. . . that still ranks Mia high on:
. . . ECONOMY, SIMPLICITY, FLEXIBILITY & EFFICIENCY!
