ADELANTO, Calif. — This is the third article in a four-part series on regenerative braking characterization by Marco Victorero, Test Engineer, Braking Systems in Applus IDIADA.

Review part 1 here

Review part 2 here

The objective of this article is to present new advanced testing procedures for regenerative braking. The two first parts of the article introduced the work and presented the methodology –test procedure, instrumentation, post-processing formulae, etc.– for the vehicles whose regenerative system was characterized in terms of durability and performance testing. This 3rd part will focus on the results for the brake durabilities: Vehicle 1 completed a short Los Angeles City Traffic (LACT) test, while Vehicle 2 data was gathered across a Mojácar durability.
