Battery State of Health (SoH) API: Now Available for EV Industry Players

Bib batteries' API delivers battery State of Health remotely, without hardware, at scale. Battery SoH is now a standardized, traceable, API-ready signal that plugs directly into the existing workflows of every player who needs reliable battery health data to make decisions.

How the Battery State of Health (SoH) API Works

The API computes battery State of Health remotely from vehicle data. No OBD dongle. No physical inspection. No manual process.

The SoH result is standardized, traceable, and delivered instantly. It is designed to integrate into existing B2B platforms without friction.

Who Uses Battery SoH Data and Why

Battery health data is useful wherever a decision depends on the real condition of an EV battery. For example :

• Leasing companies use it to assess residual value at end of contract. Instead of estimating battery health, they get a measured SoH score tied to the specific vehicle.
• Marketplaces use it to certify vehicles before listing. Battery State of Health becomes part of the listing, not an afterthought.
• Garages and dealerships use it to add battery health to inspection reports. A standardized SoH result sits alongside the rest of the vehicle check.
• Insurers and guarantors use it to price risk on EV batteries. Reliable battery SoH data makes underwriting more accurate.

Why Remote Battery Health Testing Matters for EV Valuation

Battery State of Health is the most important variable in EV valuation. A used EV with 95% SoH and one with 72% SoH are not the same asset.

Remote SoH testing at scale closes that gap : it turns battery health into a signal that flows automatically into pricing engines, inspection tools, CRM platforms and risk models.
