1. A system for monitoring a plurality of electric vehicle batteries, the system comprising:
- a battery monitoring server, communicably linked to the plurality of batteries via battery readers via a wide area network, and configured to receive data from the battery readers, the battery monitoring server being configured to, for each of the plurality of batteries, perform battery monitoring actions based on the received data, wherein the battery monitoring actions include;
detecting, based on received data, a first lifecycle change point based on degradation in battery capacity of the battery below a first threshold battery capacity;
generating in response to detecting the first lifecycle change point, a notification that the battery is to be repurposed from a present use to an alternative use apart from its respective electric vehicledetecting a second lifecycle change point based on degradation in battery capacity of the battery below a second threshold battery capacity during the alternative use of the battery, wherein the second threshold battery capacity is lower than the first battery capacity; and
generating, in response to detecting the second lifecycle change point, a notification that the battery is to be recycled.

Abstract
The disclosed invention provides a system and apparatus for monitoring battery status and usage to facilitate battery protection, battery repurposing and battery maintenance. Wireless interrogation of a battery'"'"'s location and key attributes provides efficiencies to manage the total lifecycle of an electric vehicle battery, whether installed in a vehicle or in an environment external to the vehicle environment. A wireless battery tether, combined with a wireless battery reader, a wireless battery gateway and a centralized battery monitoring server allows management of the high-voltage battery through its lifecycle.

8. A method for monitor, via a battery monitoring server, battery life associated with a plurality of electric vehicle batteries, the method comprising, for each of the plurality of batteries:
-
receiving data from a battery reader connected to the battery; detecting, based on received data, a first lifecycle change point based on degradation in battery capacity of the battery below a first threshold battery capacity; generating. in response to detecting the first lifecycle change point, a notification that the battery is to be repurposed from a present use to an alternative use apart from its respective electric vehicle; detecting a second lifecycle change point based on degradation in battery capacity of the battery below a second threshold battery capacity during the alternative use of the battery wherein the second threshold battery capacity is lower than the first battery capacity; and generating, in response to detecting the second lifecycle change point, a notification that the battery is to be recycled.
