Why to test the battery

Preserve the performance of your battery

The traction batteries of electric or hybrid vehicles degrade over time. Factors such as storage time, temperature, charging habits, number of superchargers, and even driving style have an impact on battery performance and wear.

Increase the value of your electric vehicle

The value of a used electric vehicle is strongly linked to the state of health of its battery, the cost of which can be up to 20,000 euros to repair. It is therefore essential before making a purchase to know the remaining energy capacity and predict its future wear.

Anticipate your battery life

Based on our experience in electric vehicles, our tools allow us to test and simulate different use cases. We then model the battery of your electric vehicle, we calculate its state of health and we can predict its remaining life.

An innovative methodology to test your battery

My Battery Health uses an innovative diagnostic method, based on long experience and an increased understanding of battery aging mechanisms. Our analysis software uses data from manufacturers, and the latest vehicle information.

My Battery Health is the story of three engineers who have been immersed in the world of computing and electric vehicles for years.

They were among the first French drivers of Tesla, the iconic precursor manufacturer of electric cars. The three founders quickly identified the need to have reliable and secure indicators for the maintenance of their environmentally friendly vehicle. They looked at a solution to predict and optimize battery life.

That’s when My Battery Health was born in 2020.

Drawing on their experience in electric vehicles, their tool makes it possible to test and simulate different use cases, to optimize the operating strategy and to predict the remaining life of the batteries.
