BMW's technical data lists the 60 Ah battery at 21.6 kWh gross and 18.8 kWh net, at 360 volts, with a 7.4 kW on-board charger and 50 kW DC charging through a CCS port. The optional range extender is a 647 cc two-cylinder gasoline engine that drives a generator and does not power the wheels.

Manufacturer spec

Low

BMW describes the battery as eight modules of 12 cells each, cooled by the air-conditioning refrigerant, with the fluid also able to warm the pack through a heat exchanger.

Manufacturer

Low

BMW made DC fast charging standard on the i3 for model year 2015. It was an option on the 2014 car.

Manufacturer

Low

NHTSA 17V-088 (February 2017) covers 2014-2017 i3 cars with the range extender. The fuel tank vent line may rub against the 12-volt battery cable's sleeve and leak fuel vapor. Dealers inspect the line, replace it as necessary and add a clip, free of charge. This is not a high-voltage battery recall.

NHTSA recall

Low

BMW's warranty covers the high-voltage battery against defects for 8 years or 100,000 miles and against excessive capacity loss for the same period, defined as a net capacity below 70 percent of its original value at a BMW center's check. On range-extender cars registered in California-emission states the traction battery is covered for 10 years or 150,000 miles.

OEM warranty

How this pack ages (industry context)

Industry fleet aggregates: 2.3% average annual capacity loss across 22,700 EVs / 21 models (Geotab, 2026), and 95% range retention at 5 years on average across 30,000+ vehicles (Recurrent, 2026).

OEM warranty floor on this pack: 8 yr / 100k mi to 70% capacity.

Public per-pack degradation curves are not available for most models. Individual results vary materially with climate, charging behavior, and DC fast-charge frequency.

19V599000 Aug 14, 2019 HYBRID PROPULSION SYSTEM

BMW of North America, LLC (BMW) is recalling certain 2019 i3 BEV, i3 REx, and i8 vehicles. A circuit board problem within the Electric Motor Electronics (EME) module may shutdown the supply of high-voltage electrical power.

Consequence: A shut down of high-voltage electrical power would result in a loss of propulsion, increasing the risk of a crash.
