Abstract:

Efficient battery second use strategies paves way for extracting additional services and revenue from the battery in a post-vehicle application. The total lifetime value of the battery can be increased, and the cost of the battery can be reduced to both the primary and secondary users. Availability of onboard diagnostics data and accurate assessments methods for automotive and second use battery degradation becomes crucial. However, accuracy of battery health monitoring techniques, market adoption, lack of efficient repurposing methods, lack of battery monitoring standards and policy gaps act as major barriers for developing an efficient reuse ecosystem. Identification of suitable method of reuse largely depends on the application to which the battery is redeployed. The next article in this series would focus on major second-life applications of EV batteries and a brief overview of key companies and the application they cater to. Further a possible way forward for developing an efficient reuse ecosystem would be briefed.
