EA Elektro-Automatik, a leading manufacturer of DC programmable power supplies, bidirectional power supplies and regenerative electronic loads, announced a compact, automated battery cycler and test system that will enable manufacturers to better test EV batteries as the industry evolves to higher power battery technologies.
“As consumers demand EV batteries with higher storage capacities, producers need test systems with higher power capability. In addition, the new hydrogen fuel cells coming onto the market will require even more”
The 10300 Series ATE system offers industry-leading power density: 300 kW in a single 42U-high rack that consumes only 6.5 square feet of production-floor space, one-third the space of the leading brand. Users may parallel racks for up to 3.84 MW of testing capability. This advance is a significant advantage for the industry, where production floor space is at a premium or just unavailable.
The new series offers an unbeaten 2000 VDC capacity for testing high-voltage battery packs, a level of test performance that is out of range for most competitive systems. In addition, each rack can supply and sink up to 2,400 A per rack, and the system offers up to 30,720 A total capacity. This facilitates battery pulse testing, which may require exponentially higher current than the battery AH rating.
Until now, the only way to get this performance was to build and maintain an expensive custom system. In contrast, the off-the-shelf 10300 Series is a complete COTS turnkey solution. In addition to battery cycling, tests include drive cycle simulations and insulation resistance. The test system can control an environmental chamber and communicate with a battery management system through the CAN bus interface.
Included drag-and-drop system software enables quick and easy test setup and execution. Many other suppliers charge extra for software, which may require coding to update tests.
Significantly, the new battery test system is priced about the same as competing systems that offer lower capacities and far less than the cost of integrating a custom test solution.
“As consumers demand EV batteries with higher storage capacities, producers need test systems with higher power capability. In addition, the new hydrogen fuel cells coming onto the market will require even more,” said Eric Turner, Americas Director of EA Elektro-Automatik. “Voltage levels as a result are increasing; in some cases, power grid batteries need to be tested now at 1500 volts,” he added. “The introduction of the 10300 Series now means there is a production battery test system that is finally capable of meeting emerging voltage and power demands.”
Cool, Efficient, Fast Operation
The 10300 Series ATE test system is based on EA Elektro-Automatik’s bidirectional power supply featuring SiC-based switching that provides cool, efficient, and fast operation.
The system returns absorbed power to the grid with up to 96.5% efficiency, which can save thousands of dollars per year in air conditioning costs compared to other systems.
System slew rates are at least twice as fast as other systems, enabling more precise testing.
Fast data acquisition rates up to 1.5 kHz capture events that other test systems miss.
True Autoranging Smooths Testing
In addition, the system’s bidirectional power supplies have true autoranging output for both sourcing and sinking. True autoranging allows a wider range of voltage and current, plus the ability to deliver and absorb full-rated power down to 1/3 of the maximum rated voltage. Unlike a system that does not have true autoranging, the 10300 Series system can perform a cycling test without requiring interruption to allow the system to change range as battery pack voltage ramps up or down.

The Mobility House (the company), a global provider of electric vehicle charging technologies and solutions, has released the first-of-its-kind technical guide to automated load management (ALM), a technology that will be increasingly essential to powering the electric vehicle (EV) transition. The report draws on The Mobility House’s experience and data from managing more than 1200 smart charging sites worldwide, including more than 100 “oversubscribed” sites, the term used for sites where ALM is used to install electric vehicle supply equipment (EVSE) nameplate capacity that exceeds the site’s utility connection. This is the essential purpose and value of ALM – to reduce or eliminate the need for upgrades by controlling charging load within a set limit.
ALM is essential for the U.S. to meet its ambitious electrification goals. U.S. electrical distribution utilities are now experiencing the very beginning of what will be an unprecedented amount of grid upgrade requests, particularly as Medium- and Heavy Duty fleets are incentivized to electrify by state mandates and recent federal legislation. Due to a mismatch between EV installation and grid construction timeframes, as well as grid component and labor shortages, utility distribution upgrades are becoming a major bottleneck to fleet electrification.
ALM technology is now widely used for EV charging applications in Europe and increasingly in the U.S. and is accounted for in every edition of the National Electrical Code, which governs permitting in the U.S., since 2014. However, there has been no publicly available technical guide to which fleets, utilities, electricians, engineers and other stakeholders could refer, until now. This guide will help establish a common baseline understanding of the capabilities of ALM, the appropriate use cases for its deployment, and the regulatory and procedural frameworks stakeholders can refer to, establishing new collaborative and mutually beneficial EV energization processes.
The Technical Guide touches on the well-documented challenges faced by utilities and stakeholders that need upgrades to distribution level grid infrastructure at Medium- and Heavy Duty fleet charging sites that previously didn’t have significant energy demand. The report explores various options to provide sufficient power on a constrained site without ALM, and compares those to scenarios in which ALM is used. The paper discusses how ALM is considered in the National Electrical Code (NEC), explores case studies from the U.S. and E.U., and proposes a recommended process for securing approvals from your local authority having jurisdiction (AHJ).////
BMW Group, Ford Motor Company and American Honda Motor Co., Inc. today announced that they have entered into an agreement to create ChargeScape, LLC, a new equally-owned company that will create a single, cost-effective platform connecting electric utilities, automakers and interested electric vehicle customers. Benefiting both EV customers and the electric utility industry in the U.S. and Canada, ChargeScape will unlock entirely new value that EVs can provide to the electric grid, while enabling EV customers to earn financial benefits through a variety of managed charging and energy-sharing services never before possible with traditional gasoline-powered vehicles. The closing of the transaction and subsequent formation of ChargeScape is pending regulatory approvals, with the company expected to be operational early next year.
Building on years of OVGIP cross-industry collaboration, ChargeScape’s single platform will eliminate the need for individual integrations between each automotive brand and each electric utility. ChargeScape’s platform will give electric utilities access to EV battery energy across a wide pool of EVs. Participating EV customers will have the potential to earn financial benefits by charging at “grid-friendly” times through flexible and managed schedules. Electric vehicle customers will also eventually have the opportunity for even more significant impact by sharing the energy stored in their EV batteries with the grid during times of peak demand through vehicle-to-grid (V2G) applications.
ChargeScape will enable the smart use of plugged-in EV batteries by securely providing energy data to electric utilities and system operators like aggregated demand response, alignment of charging and EV battery utilization with off-peak, low-cost hours and the availability of high renewable energy. Due to the efficient integration with participating automakers and the anticipation of high levels of EV customer enrollment, these energy services are expected to be a cost-efficient, operational benefit for electric utilities.
The development of this project comes at a time when electric vehicle sales and infrastructure growth are ramping up quickly, bringing new opportunities to address challenges for the electric grid. More EVs on the road means increased electricity demand on utilities to charge them. ChargeScape aims to provide energy management services to help support grid resiliency while looking ahead to the future of V2G capabilities that will benefit both EV customers and electric utilities.
Additionally, ChargeScape will play a role in helping to decarbonize the grid. The company’s efforts will reduce EV customers’ personal carbon footprints by utilizing electricity that comes from more readily available renewable energy sources, such as wind or solar. While seamless integration between EV customers and utilities will be key to energy management success, participating EV customers will always remain in control of their charging and energy decisions.
“Electric grid reliability and sustainability are the foundation for an EV powered future,” said Thomas Ruemenapp, Vice President, Engineering, BMW of North America, LLC. “ChargeScape aims to accelerate the expansion of smart charging and vehicle-to-everything solutions all over the country, while increasing customer benefits, supporting the stability of the grid and helping to maximize renewable energy usage. We’re proud to be a founding member of ChargeScape and are looking forward to the opportunities this collaboration will create.”
“Electric vehicles are unlocking entirely new benefits for customers that can save them money while supporting grid resiliency and increase the use of clean, renewable energy,” said Bill Crider, global head of charging and energy services, Ford Motor Company. “ChargeScape will help accelerate the true potential of the EV revolution by providing significant benefits to both utilities and EV customers through smart vehicle-to-grid services.”
“As Honda seeks to achieve our global goal of carbon neutrality, we are counting on this platform to create new value for our customers by connecting EVs to electric utilities, strengthening grid resources and reducing CO2 emissions,” said Jay Joseph, vice president of Sustainability & Business Development, American Honda Motor Co., Inc. “With automakers accelerating toward the electrified future, we must find solutions like ChargeScape that enable all stakeholders to work together for the good of our customers, society and our industry by enabling greater use of renewable energy for and from mobility.”
Benefits of Working Together
ChargeScape, along with the work done to date through OVGIP, will bring managed charging benefits to more EV customers and can eliminate marketing and outreach costs for utilities trying to reach their individual customer bases. BMW Group, Ford Motor Company and American Honda have direct, multi-channel communication with their EV customers, solving a central problem for utilities that typically do not know or have an easy and cost-effective way to identify the EV customers in their service territory.
Additionally, by leveraging automaker telematics, ChargeScape intends to provide managed charge scheduling through vehicle connectivity without requiring Wi-Fi-enabled charging stations. This will support the many EV customers who do not use “smart” chargers at home, as their EVs would otherwise be unreachable for grid services.
The three founding members welcome other automakers to join in and fully unlock opportunities provided by ChargeScape’s grid service offerings once the company is fully operational./
