units may experience shutdowns on pressure due to frozen coolant lines, which shortens the useable lifespan of the equipment.
• Cold supply air that is contained will be forced to ow through the battery racks, where it will absorb heat energy and then be transported directly back to the cooling units. For a traditional, uncontained, raised- oor BESS with perforated oor tiles, more than 50 percent
of the cold air supplied from the cooling unit(s) will bypass directly back to the cooling unit(s) as a result of any open paths and/or leakage points that exist.
• Contained hot air returns guarantee an unobstructed path back to the cooling unit(s), which improves system e ciencies.
• Cooling system energy savings will increase and maintenance/ replacement costs will decrease by being able to use a lead-lag operation logic with cooling units that become redundant.
• Provide a stable environment for the use of economizer cooling or “free cooling” technologies that work
by delivering and trading outdoor air into the system that is cooler than the temperature of the indoor air. When the economizer mode
is operational, the cooling system compressors do not work to reject heat to the outdoors, resulting in lower overall operating costs and longer equipment life.
• Can work with almost all stored energy installation con gurations and is compatible with re detection/ suppression systems, lighting, and other ancillary subsystems.

Quick EV charger with
modular technology
Circontrol’s new DC quick charging station, Raption
50, includes modular technology, which allows bigger uptime and increases exibility, without sacri cing a stylish and modern design. is third-generation quick charger increases its uptime and the availability for users thanks to its functioning modular power technology with four individual power packs delivering 12.5kW each.
e Raption series also o ers exibility through scalable power, so if a local power network doesn’t support rapid charging or if a user only needs to draw 25kW of power,
it may adjust the supply. Designed specially to be placed where vehicles need to be ready to continue their journey in less than half an hour, such as fuel stations, road-side rest areas, or airports, the new unit completes an 80% charge in 30 minutes with simultaneous charging for two EVs at 50kW DC and 43kW AC. e Raption 50 Series
has a sophisticated and slim enclosure but is robust and ensures high durability. Another key attribute of the new Raption 50 is its usability. It includes a user friendly and fast 8" touchscreen daily readable with multiple language options, an inbuilt light for better visibility at night, and/ or secure charging connector holsters that can only be unlocked from the charging station with a veri ed RFID card or with the backend authenticate protocol, reducing damage to the equipment through improper use or vandalism. In addition, the Raption 50 emits no audible high frequency noise and the height of connectors/ display has been adapted for disabled.

Testing-based verification tool
for battery lifetime
DNV GL has created Battery XT, a testing-based veri cation of battery lifetime for Li-on batteries. e independent veri cation tool compiles battery life cycle data and predicts battery degradation under di erent conditions and duty cycles, providing renewables stakeholders with an objective way to compare the value and reliability of types and brands of energy storage technology. Battery XT o ers an independent third- party testing and veri cation of product warrantees and performance guarantees before making a purchasing decision. Battery XT, which can also provide consulting on battery size and chemistry selection, aims to reduce risk and inform purchases and planning for energy storage asset management. e independent veri cation enables the industry to test at a low cost, helping stakeholders save time and money by eliminating the need to address individual, customized testing protocols for each vendor. DNV GL o ers an interactive online demo to illustrate the way Battery XT works. Viewers
can try three scenarios—fast charge electric ferry, hybrid genset, and solar+frequency by entering sample information such as system size, temperature, and initial state of change, and then running a simulator to show how the factors apply. e full service o ered on a per project basis is able to tailor even the most complex duty cycle to the customer and their battery.

EMF meter for extremely low frequencies
Extech Instruments’ EMF510 is a single-axis electromagnetic eld (EMF) meter optimized for measuring extremely low frequencies (ELF). e compact new meter makes it easy to measure EMFs in the 30 to 300Hz frequency range, making it useful for applications from utilities to product development and engineering. e EMF510 features an informative, oversized dual display indicating both EMF reading levels and the selected EMF range. Users can measure EMF/
ELF levels in either milliGauss (mG) or microTesla (μT) units in two ranges up to 2000mG (200μT) with +/-5% accuracy. Useful data functions include data hold, as well
as minimum and maximum readings. A bright backlight adds versatility for testing in dark job sites. e auto-power- o function preserves battery life and can be disabled for extended monitoring. e pocket-sized EMF510 is always ready for testing by utilities of EMFs found in the generation, transmission and distribution of electricity, with power lines and substations, as notable examples. Product development and electrical engineers can use the EMF510 to quickly assess EMF levels generated by electrical components such as motors and blowers. Homeowners can use the meter to measure EMFs in household wiring and appliances from vacuums and hair dryers, to electric and hybrid vehicles.
A wrist strap is useful for toting while a tripod mount lets users set up the meter with consistent placement to avoid variability in routine measurements (using an optional tripod, TR100). e EMF510 is backed by Extech’s one-year warranty and comes with three AAA batteries.

Simple energy storage quoting tool
for solar dealers
JLM Energy’s Simple Quoting and Design tool, or SQUAD is a straightforward way for solar dealers to provide residential quotes on solar plus JLM’s MicroStorage product Phazr. Phazr pairs each solar panel with a battery pack for a streamlined approach to solar plus storage. SQUAD 1.0 brings time-of-use shifting solutions to California residents, where time-of-use pricing has recently changed in San Diego Gas & Electric Territory
in a way that reduces the value of standalone solar.
is means homeowners can save their solar power in batteries for hours later in the day when the utility is charging higher rates and people are generally using more electricity. SQUAD is designed to be used at the kitchen table with the homeowner. e sales person plugs in answers to customer lifestyle questions, enabling SQUAD to calculate the ideal combination of solar plus storage along with system pricing. SQUAD generates a sleek, one-page summary of system cost
and savings as a leave behind at the conclusion of the in-home consultation. SQUAD uses JLM’s proprietary software Measurz to perform powerful calculations behind the simple user interface. Future versions will include demand shaving and self-supply algorithms. JLM Energy | www.jlmei.com
