Abstract

A system and method for management of an energy storage system for a vehicle is disclosed. The energy storage system may comprise a battery system for a vehicle such as an electric vehicle or hybrid-electric vehicle. Vehicles may be in a group of fleet. The management system may be configured to use data and information available from data sources over a network or by instrumentation/sensors for vehicle systems. Data and information could be used in a system to manage the configuration and operation of the energy storage system and components, manage/control inventory and use/life-cycle of components, and/or aggregated/analyzed in analytics function for systems and components. Predictive control of the battery system may be implemented through a management system using data sources external to the vehicle. Inventive concepts and features of the systems and methods are indicated in the specification and FIGURES.

Claims

1-213. -213. (canceled)

214. A method of predictive management of a battery system in a vehicle comprising vehicle systems including the battery system comprising the steps of:

(a) obtaining data relating to the vehicle in data categories from data sources;

(b) determining a duty for the vehicle;

(c) determining a configuration of the battery system;

(d) evaluating data to predict anticipated conditions of operation for performance of the duty;

(e) operating the vehicle and vehicle systems according to data from data sources, predicted conditions of operation and considerations including at least predetermined objectives;

(f) monitoring conditions of operation of the vehicle in performance of the duty to obtain data from data sources;

(g) using data from data sources based on predicted conditions of operation to perform the duty to configure and manage the battery system; and

(h) modifying the actual duty to be performed by the vehicle, by at least one of setting a new destination for the vehicle, modifying an objective to be carried out by the vehicle, or modifying a route of the vehicle to a predetermined destination, in response to (A) predicted conditions of operation to perform the duty, prior to modification of the duty and (B) monitored conditions of operation of the vehicle in performance of the duty, prior to modification of the duty.

215. The method of claim 214 wherein the battery system comprises at least one battery module.

216. The method of claim 214 further comprising providing a management plan for operation of the vehicle.

218. The method of claim 214 wherein a computing system implements predictive management of the battery system through an operating program using data from data sources.

219. The method of claim 214 further comprising assessing the status of vehicle systems including the battery system.

220. The method of claim 214 further comprising modifying the duty to be performed based on obtained data related to environmental conditions along a route of the vehicle.

222. The method of claim 214 further comprising obtaining data over a network.

348. The method of claim 214 wherein data categories comprise (a) data sources from external sources to the vehicle and (b) data sources from vehicle systems.

349. The method of claim 214 wherein the data sources comprise data relating to operating conditions for the vehicle in performance of the duty.

350. The method of claim 214 wherein the data sources comprise data relating to

(a) duty or route of the vehicle;

(b) operator of the vehicle;

(c) type of the vehicle;

(d) configuration of vehicle systems;

(e) operating conditions of the vehicle in the duty; and

(f) environmental conditions of the vehicle in the duty.
