We are extremely proud of our strategic partnership with Generational, the pioneering UK-based innovator in electric vehicle battery health certification. Launched in 2023, Generational’s proprietary testing technology delivers fast, accurate State of Health (SoH) assessments and real-world range predictions by plugging directly into an EV’s OBD port—empowering dealers, fleets, and buyers with transparent, third-party-backed certificates that build unmatched confidence in used EVs. Backed by the UK’s Advanced Propulsion Centre and trusted by industry leaders like us here at Lease Cars Direct. This collaboration aligns perfectly with our commitment to sustainable mobility, allowing us to offer customers the peace of mind they deserve as we drive the transition to a greener automotive future together.

What is a Battery SOH Certificate?

The certificate includes a complete report on the electric car battery:

The SOH (State of Health) of the battery

Other important indicators to help you understand your battery’s health

Theoretical autonomies under different driving conditions

The certificate provides you with essential information when purchasing an electric vehicle.

What Does The SOH % Mean?

As an electric vehicle ages, its range decreases. This decrease is due to the chemical and physical degradation of the traction battery (i.e., the electric-vehicle battery, which powers the motor). This phenomenon, known as aging, depends heavily on the specific conditions in which the vehicle is used and stored, and is therefore unique to each car.

The ‘Generational‘ battery test certificate indicates the State of Health of your electric-vehicle battery at a given time.
