The BMW i3 or upgraded lithium-ion batteries to have more capacity

Since its first launch in 2013, BMW's i3 has undergone minor incremental upgrades and updates of large battery cores. According to foreign media reports, there are rumors that the pure electric car will upgrade the battery core again, and its range may exceed 200 miles.

Over the years, to improve vehicle range, BMW has worked with its battery battery supplier, Samsung SDI, to verify that the energy density of the cell core in its existing battery pack can achieve longer range.

The last BMW i3 battery core upgrade took place in 2016, when the battery core capacity was upgraded from 60h to 94h, and the entire battery package was upgraded from 22 kilowatt-hours(kWh) to 33 kilowatt-hours.

Now equipped with a new battery core with a capacity of 120 Ah, the total battery pack energy will reach 42 kilowatt-hours.

According to BimmerToday, BMW is intensively preparing for the debut of the BMW i3 with a battery capacity of 120 Ah. Lithium-ion batteries have larger capacity and longer range. According to the new European Driving Cycle(NEDC), this more powerful battery pack will allow its range to exceed 350 kilometers.

It is not yet clear how the BMW i3 with a battery capacity of 120 Ah can reach 350 km NEDC. However, if the BMW i3 is equipped with a 42-kilowatt-hour battery pack, it is reasonable to achieve a range of 350 kilometers(217 miles) under NEDC conditions.

However, it would be surprising if the actual range of driving could be close to 200 miles when full of electricity. At present, the BMW i3 can reach 114 miles in cash and, more realistically, the new battery pack will have an electric range of about 150 miles.

Currently, BMW is developing a new generation of electric powertrain technology, which it hopes will be launched on ix3 for the first time in 2020. The car will be reequipped with a new electric power system architecture such as BMW's new battery pack and motor, rather than just a new battery core.
