MOBI Battery State of Health (SOH)

2022: Electric vehicle battery standard approved

In May 2022, the MOBI blockchain alliance approved the first battery standard for electric vehicles. It was named Battery State of Health. The standard will allow users to find out the current state of the batteries and assess the vehicle's range, as well as data will help with the disposal and reuse of the battery, and can also be used by insurance companies.

20 companies took part in the development of the standard, including automobile BMW, Ford, GM and Honda. In addition to some manufacturers, the final version of the document was considered by employees of Accenture, Hitachi and DENSO. All parties agree that as soon as the battery capacity is reduced to 80% of the original value, its service life comes to an end. Although the battery can be perceived as a single unit, in reality it consists of many components and elements, and each of them also has a state of health. This is particularly important when it comes to recycling and reuse.

The battery state describes the difference between a fully charged battery and the same battery in use. The charge is associated with the remaining amount of electricity available in the cell. It is defined as the ratio of the remaining battery charge to the maximum charge that the battery can provide. The standard describes the state of battery health and the difference between the user's battery and the new battery, and also takes into account the aging of the cell.

{{quote 'MOBI and our members expect this first SOH battery standard and MOBI's battery initiative to promote a greener, more sustainable global battery value chain and accelerate our shared goal of a sustainable, low-carbon transportation future, "said MOBI Director and Founder Tram Vo. }} The Battery State of Health (SOH) standard is part of the MOBI initiative, which aims to create a framework for compliance with both California's CARB regulations and the European battery directive. The consortium has several working groups, and one of them focuses on integrating a public key certificate with enhanced authentication of the authenticated object into the network. The car's battery can store excess energy generated by home solar panels, allowing peer-to-peer electricity trading.^[1]
