What type of battery does the BMW i3 use?
2 Answers
BMW i3 uses lithium-ion batteries, which are a type of secondary battery (rechargeable battery) that primarily relies on the movement of lithium ions between the positive and negative electrodes to function. The BMW i3 is a pure electric compact car under the BMW brand, featuring an advanced electric drive system. This system is very similar to the all-electric drive system of the BMW 1 Series ActiveE, with a maximum output power of 167 horsepower, delivering power to the rear wheels. In terms of body dimensions, the BMW i3 measures 3999mm in length, 1775mm in width, and 1578mm in height. Inside the vehicle, the interior design of the BMW i3 closely resembles that of the MINI Clubman, emphasizing the practicality of the vehicle.
The BMW i3 primarily uses lithium-ion batteries, specifically the lithium nickel cobalt manganese oxide (NCM) ternary type. I particularly appreciate this battery's high energy density, as a single charge can provide a range of around 200 kilometers, making it very practical for urban commuting. The battery is composed of multiple modules, with Samsung SDI being the main supplier. The entire system supports fast charging, allowing it to reach 80% charge in just half an hour, which is very convenient for daily use. The downside is that after some time, aging issues become noticeable, and replacement costs are high. BMW has considered heat dissipation optimization and recycling mechanisms in its design, but users often complain about significant depreciation in the second-hand market. It is recommended to assess the battery's health before purchasing. The new version has improved battery capacity, and overall durability is quite good.
