The battery: 50% of your EV value

The value of an EV battery

An electric vehicle's battery represents up to 50% of your vehicle's value. It is a "financial" asset just like the rest of the electric vehicle, and it requires specific care.

Asset ownership

This asset may sit on the balance sheet of a leasing company, an OEM captive, a corporate, or be owned directly by an individual just like the electric vehicle itself.
Like the electric vehicle, the battery requires proper maintenance to preserve its financial value.

Battery lifespan and depreciation

The battery is an energy reserve and an asset with a finite lifespan. Once its charge cycles are exhausted or its recharge capacity falls below a certain threshold, it must be replaced, repurposed to a second life, or recycled.

Diagnosis and value

A reliable, independent battery state-of-health diagnosis is essential, especially before resale. Cara7 helps preserve and maximize the resale value of the battery and the electric vehicle.

Market asymmetry

Transparency and information symmetry between the two parties (buyer and seller) are key elements in a used vehicle transaction. This was beautifully demonstrated by George Akerlof, PhD in economics, Berkeley professor and 2001 Nobel Prize in Economics, with his theory of market asymmetry, illustrated by the used car market.

Cara7 provides a digital vehicle passport — a dynamic NFT that notarizes the vehicle's history in an immutable, tamper-proof and enforceable way, based on certified-source data.

Value premium for EVs

Your vehicle will earn a premium on the used market. This is even more true for EVs, where close to 50% of the value sits in the battery.
