Introduction:

 Sustainability and climate change mitigation requires global net-zero emissions by 2050. This transition demands tripling wind and solar capacity, phasing out coal power and expanding power transmission infrastructure. To meet these targets, zero-emission vehicles and heat pumps must capture 50% of market share by 2030. Current technology enables this transition, but rapid deployment of infrastructure remains essential.

Global System Integrators (GSIs) like HCLTech, in collaboration with Hyperscalers like AWS, are now pivotal in orchestrating intelligent EV ecosystems. By leveraging HCLTech’s deep automative vertical expertise and AWS’s scalable AI/ML and IoT stack, OEMs can rapidly bridge infrastructure and intelligence gaps – transforming EV adoption from hardware challenge to a software-defined experience.

Electric vehicle (EV) adoption faces specific challenges and new EVs will reach 300-mile ranges and achieve price parity with combustion engines by 2026. To accelerate adoption, the charging infrastructure requires two key improvements: reducing charging times from current 30-minute averages to under 10 minutes and increasing charging station density from current 1:14 ratio (charging stations to gas stations) to 1:3 by 2030.

The need:

The expanding electric vehicle market faces a persistent challenge: charging confidence. Current data shows a stark infrastructure gap, with only 46,000 EV charging stations compared to 150,000 gas stations across the United States. This disparity creates two distinct challenges for drivers: operational planning and psychological barriers.

EV owners must actively manage their charging needs through pre-trip planning and real-time monitoring. The scattered charging network, combined with varying charging speeds and inconsistent station reliability, creates practical hurdles for daily operation. While most EV owners completing regular commutes rarely encounter charging issues, long-distance travel requires additional preparation. Real-time charging apps and integrated vehicle navigation systems now help address these challenges by providing live station availability and route planning features.

 Solution:

The GenAI EV Assist combines artificial intelligence and Internet of Things (IoT) technology to transform the electric vehicle experience. This system delivers personalized charging recommendations, efficiency optimization and emergency assistance through real-time data analysis. By integrating advanced navigation features with vehicle-to-everything (V2X) communication, it provides drivers with comprehensive support that builds confidence in electric mobility. What differentiates this approach is the ability to orchestrate cross-domain data-from telematics, user behavior and infrastructure-to cloud-native AI services. HCLTech’s GenAI accelerators on AWS Bedrock can fine-tune LLMs using proprietary EV datasets, enabling ultra-contextual driver assistance that adapts to regional infrastructure and driving patterns.

 Below solution components integrate together with data exchange to enable required insights for the users: 

1. IoT, custom data signals and voice commands processing and transmission: 
   1. Vehicle sensors data is collected at edge (vehicle controller) level – Vehicle Database (DBC) | Global Positioning System (GPS) | Last Known State (LKS) | Custom sensors Data 
   2. Capability to understand voice commands from user, process them and transmit necessary commands to cloud 
2. Driving efficiency recommendations: 
   1. Embedded Machine Learning (ML) model analyses the vehicle data to assess the driving style and suggests adjustments in speed, eco-mode and route to enable maximize battery efficiency, with access from knowledge base (multiple sources like research papers/OEM manuals) 
   2. Provides this information to GenAI engine which in turn provides real-time feedback to the driver on their driving behavior and its impact on the remaining battery life 
3. Charging assistance based on low battery alerts: 
   1. The system continuously monitors the battery status of the EV 
   2. Capability to alert the driver when the battery level drops below a certain threshold, providing real-time updates
   3. Identifies the nearest available charging stations based on the vehicle's GPS coordinates 
   4. Provides detailed information such as location, charging characteristics and estimated recharge time 
   5. Provides multiple point of interest options like parks/restaurants/malls nearby within a walkable range of the charging station to enable effective time utilization 
4. Automated towing service: 
   1. Monitors the battery level and detects when it is critically low and identifies situations where the vehicle is unlikely to reach any nearby charging station 
   2. Connects the driver with nearby towing providers 
   3. Flexible raising respective towing requests with the towing providers by sharing contact details, estimated response time and associated fees for recommended optimal choice 
5. Weather-based updates: 
   1. Monitors the location’s weather 
   2. In case of severe weather updates, alerts the driver on effects on EV batteries and recommendations on changes to driving style 
6. Processing engine: 
   1. Synchronized harmony between driver-vehicle-infra 
   2. Collects and integrates data from various sources such as vehicle sensors, GPS and external charging station databases 
   3. Ensures a synchronized flow of information between the driver, vehicle and infrastructure through IoT-cloud infrastructure 
   4. Processes the integrated data over the cloud to provide comprehensive and correlated information set to the driver 
7. Automatic information to driver: 
   1. Delivers real-time audio and textual notifications to the driver 
   2. Includes tips for efficient driving and alerts about battery status 
   3. Ability to integrate with the vehicle's infotainment system for a seamless user experience 
   4. Ensures that the driver receives relevant information automatically without needing to manually search for it, thus leading to a drastic reduction in driver anxiety and improving confidence on EV

Technical architecture:

 AWS services used in the solution:

1. AWS IoT FleetWise: This is the core of vehicle data ingestion and management. It facilitates the secure collection, processing and organization of data streaming from connected vehicles. The diagram shows it operating at the edge (within the vehicle gateway) and in the cloud. The edge component (Edge Agent) preprocesses data (Vehicle DBC/GPS/LKS/custom signals) before sending it to the cloud for further analysis and storage 
2. AWS IoT Core: This managed cloud service acts as a central hub for receiving, processing and routing messages from the connected vehicles. It handles communication between the FleetWise edge agent and other AWS services in the cloud 
3. Amazon Timestream: A time-series database optimized for storing and querying massive amounts of time-stamped data. Here, it's used to store the vehicle telemetry data collected by FleetWise for analysis and reporting
