BMW introduced the i3 electric car upgraded sample 2017 model year.
BMW has expanded its family of “i” at the expense of a new modification of the hatchback i3, who received other batteries and can travel up to 300 kilometers.
When this car is available to the system to increase the power reserve, which suggests the presence of two-cylinder petrol engine to maintain a constant battery charge. In this case, you can drive for 150 miles.
Interestingly, for the installation of batteries of greater capacity the engineers had to make the design any significant changes. The company noted that the upgrade was provided at the design stage, the BMW i3.
Here, it seems a little disingenuous. What changes you need to make, if the size of panel with battery remained the same? Weight green piatigorski increased, by the way, slightly, about 45 pounds, and is now at 1245 kg.
The best part is that the owners of the “first” hatchback i3 will not feel offended. BMW offers a program for modernization of vehicle: any customer who wants to increase range, can do: the batteries of the first generation surcharge will change to battery the new sample. The program is already available in some markets.
Along with the updated BMW i3, the Bavarian company introduced a charging station the BMW i Wallbox, which later will have a few new modifications. A handy thing that allows you to charge the car faster than usual, but all in good time.
The high-voltage battery of the BMW i3 consists of eight modules with 12 cumulative cells in each. The vendor is Samsung SDI. The company increased the capacity from 60 to 94.
This required to optimize the cell structure, to increase the volume of the electrolyte and active materials. Along with this was improved electronics, new algorithms for motor control, voltage curve of a battery under load has become more efficient.
Measures allowed to increase the mileage on a single charge from 190 to 300 kilometers. But the 300 figure is very optimistic, and honestly admit that in real conditions, in poor weather conditions or with the included climate control, a power reserve will be about 200 kilometers. At i3 (60 Ah) is about 120 km In this parameter leads Chevrolet Bolt: for passport data he’s strong enough for a 320-kilometer forced March.
However, in a new BMW called the BMW i3 (94 Ah) best offer in the segment for energy consumption: per 100 km hatchback consumes 12.6 kWh (NEDC cycle).
System increase power reserve, as we have said, involves the installation over the rear axle of an internal combustion engine with a volume of 650 cm3. His maximum return is equal to 38 HP, which is enough for the generator to be included after the level of energy in the battery reaches a certain minimum.
The Luggage compartment of a hatchback is not affected: it is 260 liters, and with folded rear couch – all 1 100 liters.
All versions of the BMW i3 is equipped with a single-stage transmission, which transmits torque at speeds up to 150 km/h Faster than the hatchback will not go, as is equipped with a limiter.
The BMW i3 has received a quick charge function, which “digests” the alternating current with power up to 11 kW. The new system is expected more powerful, as battery capacity was increased. To recharge batteries you need at least three hours.
From the usual outlets i3 (94 Ah) will saturate in less than 10 hours. Let’s remind, that hatchback with the previous version of battery (60 Ah) required about 8 hours.
i3 “friends” and with a direct current power of 50 kW. At the stations the Express charging the battery you can “fill” up to 80% within only 40 minutes.
BMW i Wallbox is a device with which you can quickly charge the car both at home and in the Parking lot. From wall station has support for single-phase and three-phase current (up to 22 kW). Charging electrodata occurs in less than 3 hours.
