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.

Test the battery

Who's this application for

Les particuliers qui souhaitent vendre ou acheter une voiture électrique d’occasion. Vous pouvez sur un rapport facile à comprendre, vérifier et comparer l’autonomie de la batterie ainsi que les performances de tous les modèles électriques et hybride du marché. Vous retrouverez dans notre rapport l'historique de tous les tests de batterie effectués, présenté sous forme d'un graphique permettant de mieux visualiser la courbe d'usure et anticiper le futur.

Les conducteurs de voiture électrique qui peuvent ainsi vérifier ou suivre l’usure de la batterie de traction de leurs véhicules. Un simple test peut rassurer sur l’état de santé de la batterie ou au contraire alerter et prévenir d’une panne à venir.

Afin de mieux valoriser les véhicules, Les professionnels de la revente de véhicules, les réparateurs ou les loueurs de voitures électriques et hybrides peuvent souscrire à la version « pro » de l'application et bénéficier d’un service sur-mesure. Nous proposons un espace web dédié ou vous retrouvez l’intégralité des rapports effectués, classés par date, marque ou modèle. Le rapport de santé est imprimable et vérifiable par les futurs acheteurs à l’aide d’un QR code présent sur le document.

Ce rapport d’état de santé du véhicule vous permet de vous démarquer de la concurrence, de rassurer les futurs acheteurs, et de donner la meilleure valeur possible aux véhicules électriques ou hybrides. 

Il permet également de contrôler régulièrement l’évolution d’un pack, et d’anticiper les pannes à venir. L’immobilisation d’un véhicule électrique pour un changement de batterie de traction peut engendrer des coûts supplémentaires importants, et une anticipation peut éviter une panne grave du bloc batterie.

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.
