Telematics in EV Charging Explained


October 19, 2023

Did you know that effective EV fleet management can result in a 55% reduction in energy costs?

This remarkable achievement is made possible with the integration of telematics and smart charging solutions.

Technology such as on-board diagnostics and GPS, combined with telematics systems, help to provide valuable data about the state of vehicles and charging processes. In this way, telematics combined with smart charging software help to ensure:

  • fleet readiness, 
  • operational efficiency, 
  • and cost-effectiveness.

In this article, we’re going to show how combining the power of smart charging software with telematics can be a game-changer for EV fleet charging. 

Role of Telematics in EV Fleet Management

Telematics plays a pivotal role in fleet management. Telematics systems collect and manage vehicle information using onboard diagnostics and GPS technology. The data is sent to a cloud server and made available to relevant people, such as fleet managers. 

The data collected by telematics often includes valuable information about:

  • vehicle location, 
  • speed, 
  • idling time, 
  • harsh acceleration or braking, 
  • fuel consumption, 
  • vehicle faults, 
  • and more. 

The insights derived from telematics data boosts operational efficiency, improves safety, and lowers costs.

The Shift Towards OEM-Specific Telematics

A recent trend in the automotive industry is the shift towards OEM (Original Equipment Manufacturer)-specific telematics, rather than third-party systems. More and more vehicle manufacturers recognize the immense value of telematics data. They are starting to implement proprietary telematics systems which allow them to see and store data in their own cloud. These OEM telematics systems often provide more vehicle-specific data and greater integration and functionality, although they may also limit the options for third-party service providers.

Transitioning to EV Fleets

As fleets transition to electric vehicles, the data captured by telematics is becoming more and more important. Information about driving and distance requirements can be used to determine which ICE vehicles are best suited for replacement with EVs.

Parameters such as driving distance, fuel used, and dwell time informs infrastructure planning, ensuring the right number and type of charging stations are installed at optimal locations.

Telematics data helps fleet managers to:

  • optimize charging schedules, 
  • ensure vehicle readiness, 
  • maintain hardware uptime, 
  • and facilitate maintenance. 

Telematics also collects data that can be used to calculate the total cost of ownership of EVs, e.g. energy costs, maintenance costs, and the lifespan of vehicles.

After the transition to EVs has taken place, telematics systems are still important. They enable real-time monitoring of the state of charge, helping prevent potential issues like charger downtime or vehicles running out of charge. They also provide insights into energy usage patterns, helping to cut costs.

Overcoming Fleet Management Challenges with Telematics

Managing a fleet, particularly an electric one, comes with its own set of challenges, especially when it comes to optimizing charging operations. 

Challenge #1: Vehicle readiness 

Problem: Maintaining vehicle readiness is complex given longer EV charging times, compared to ICE vehicle refueling.

Solution: Telematics can provide fleet managers with real-time information on the state of charge of each vehicle in the fleet. This lets you identify vehicles that need to be charged and schedule them accordingly. Notifications about low battery states or completed charging can be sent to fleet managers via email, SMS, or other communication platforms, ensuring quick actions can be taken to maintain vehicle readiness.

Challenge #2: Asset downtime

Problem: Asset downtime, both of vehicles and chargers, directly impacts fleet efficiency and performance. Inefficient depot operations can prevent vehicles or chargers from being utilized to their full potential.

Solution: Telematics can help in minimizing the downtime of both vehicles and chargers. By tracking the usage and operational status of these assets, issues can be identified and addressed promptly. For example, if a charger is malfunctioning, the system can notify the relevant parties to take immediate action.

Challenge #3: Inefficient depot operations

Problem: The problems can range from underutilization of vehicles and chargers to poor scheduling of charging times, leading to vehicles not being ready when required or chargers being unnecessarily occupied.

Solution: With telematics, fleet managers can gain insights into how vehicles and chargers are being used. This can help in identifying inefficiencies in depot operations, such as a fully charged vehicle not being utilized or a charger being occupied by a fully charged vehicle. With these insights, operations can be optimized to ensure maximum utilization of assets.

Challenge #4: High energy costs

Problem: High energy costs can affect the cost-effectiveness of the entire fleet.

Solution: One of the major benefits of telematics is the ability to monitor and control energy usage. Analyzing data on energy consumption patterns, in combination with a smart charging software system, means that charging can be scheduled during off-peak hours when energy rates are lower. This can significantly reduce the energy costs associated with running an EV fleet.

Combining Smart Charging and Telematics

Ampcontrol is a pioneering cloud-based charge management software that collects and analyzes data from various sources. Charging optimization can be enabled by bringing in data such as charger diagnostics and energy tariffs, and combining it with telematics data, such as vehicle state of charge, range estimation, energy consumption and more. 

Using Ampcontrol’s powerful algorithms with external and telematics data can help to:

  • provide optimal charging schedules, 
  • ensure high charger uptime, 
  • and keep energy costs to a minimum.

Non-Standardized Vehicle Data Communication Protocols in EVs

However, a primary challenge lies in the non-standardized vehicle data communication protocols in EVs. Different manufacturers use different systems, making it complicated to create a one-size-fits-all telematics solution.

However, the industry is addressing this issue with the creation of new standards and protocols. An example is the development of ISO 15/1/8, aimed at standardizing data communication in electric vehicles. This advancement would simplify the integration of telematics in EVs, enabling fleet managers to unlock the full potential of telematics regardless of the vehicle's make or model.
