Regenmeter

Regenmeter is a term used to describe either a hardware instrument or a software-based metric that measures regenerative energy in systems designed to reclaim energy during operation. It is commonly associated with electric and hybrid propulsion, where energy is recovered during braking, as well as with other energy recovery systems in industrial machinery or test environments. The term is not universally standardized, and its exact implementation can vary by manufacturer or application.

What it measures

A regenmeter typically tracks the amount and rate of energy recovered by regeneration. Key outputs may include

How it works

In practice, a regenmeter relies on sensors that monitor electrical parameters such as current and voltage,

Applications and use

Regenmeters are used in electric and hybrid vehicles to quantify regenerative braking performance, in rail systems
