The Battery: 50% of the EV's Value

The Value of the
EV Battery

The battery of an electric vehicle makes up to 50% of the vehicle's value. It is a "financial" asset, just like the vehicle itself, and requires proper care.

Asset
Ownership

This asset can be owned by a leasing company, an OEM’s finance company, a business, or an individual. Like the EV, the battery needs proper care to maintain its financial value.

Battery Lifespan and
Depreciation

The battery is an energy reserve and an asset with a limited lifespan. Once its charge cycles are exceeded, or recharge capacity drops below a certain point, it must be replaced or repurposed for secondary uses or recycling.

Diagnostics
and Value

A reliable, independent diagnosis of the battery’s condition is crucial, especially before resale. Cara7 helps preserve and maximize the resale value of the battery and EV.

Market
Asymmetry

Transparency and information symmetry between the two parties (buyer and seller) are key elements during a used vehicle transaction. This was demonstrated by George Akerlof, Nobel Prize winner, through his theory of market asymmetry in the used car market.
