2022 BMW i7 in final development phase – Extreme load and temperature testing

Set to debut next year, the all-electric 2022 BMW i7 is currently in its final phase of development – being tested in extreme-load and extreme-temperature conditions.

Previously tested in Sweden for extreme cold temperatures, the BMW i7 is now undergoing endurance test in the hot regions of various countries and continents.

This serves in particular to test and safeguard all components of the electric drive system.

During so-called hot-region testing on tracks and public roads all over the world, the all-wheel-drive system and the high-voltage battery are exposed to maximum stress from high temperatures, unpaved roads, dust and large differences in altitude.

Among the tests conducted on the BMW i7, as mentioned by BMW, are:

Driving for tens of thousands of kilometers, including long-distance and high-speed driving as well as stop-and-go traffic in scorching heat. (Endurance testing)
Driving in hot regions with particularly large differences in altitude. (to test temperature behaviour of the electric motors and the torque control)
Mountain driving in trailer mode.(maximum load testing)
Downhill driving with fully-charged high-voltage storage system (to test energy management and power electronics)
Performance test of the air-conditioning and other on-board electronics
Temperature resistance of the materials used in the interior

The tests were supported by sensitive on-board measurement technology, experienced test engineers register every reaction of the electric motors, the high-voltage battery, drive control and the integrated cooling system as well as the charging technology and energy management to weather and road-related influences.

The BMW i7 will make its debut in 2022 together with the new BMW 7 series. According to BMW, it will be the world’s only purely electrically powered luxury sedan.
