Ametherm to Showcase NTC Thermistors for Li-Ion Batteries and Green Energy Applications at The Battery Show 2018


Highlights to include probe assembly with ring lug, inrush current limiters for input energy up to 1200 J


CARSON CITY, Nev. — August 22, 2018 — Ametherm today announced its product lineup for The Battery Show 2018, taking place September 11-13 at the Suburban Collection Showplace in Novi, Michigan. At booth 2050, the company will highlight its leading NTC thermistor solutions for Li-ion batteries and green energy applications, including its PANR 103395-342 probe assembly with ring lug for high-accuracy temperature compensation and measurement, and MM35-DIN Series and MS35 Series of inrush current limiters for reliable high-power circuit protection.


“Whether they’re being used for energy storage in solar plants or to power electric vehicles, batteries are a cornerstone of green energy, and their performance relies on accurate and reliable NTC thermistors,” said Mehdi Samii, vice president of engineering at Ametherm. “Sensors like our PANR 103395-342 help prolong Li-ion battery life and increase safety during the charging cycle, while our MM35-DIN Series and MS35 Series provide protection against inrush current at turn on in high-power renewable energy applications. We can’t wait for these solutions to make their Battery Show debut.”


For Li-ion battery power applications, the ring lug of Ametherm’s PANR 103395-342 probe assembly provides easy and secure mounting to battery terminals. The device is extremely accurate and experiences minimal drift from its initial electrical values to provide a high-stability replacement for thermocouples in electric vehicle batteries and off-grid energy storage. The temperature probe features a 4000 VAC dielectric withstand voltage, resistance at + 25 °C of 10 kΩ, beta of 3950 °K, and dissipation constant of 8 mW/°C.


Ametherm’s MM35-DIN Series of NTC thermistors are designed to withstand high input energy of 1200 J and steady-state currents from 50A to 80A at 680V. Offered in DIN-rail-mountable packages, these inrush current limiters are ideal for high-power industrial and green energy applications, including variable frequency motor drives, wind turbines, large inverters, single- and three-phase motors, and transformers. The MM35-DIN Series features resistance at 25 °C from 0.2 Ω to 1.5 Ω, with maximum power of 38.4 W.


The rugged MS35 Series of NTC thermistors are optimized for high-power applications, such as wind turbines, solar power inverters, EV battery chargers, and electric vehicles. Designed to withstand high input energy from 500 J to 900 J and steady-state currents from 10A to 50A, these devices offer resistance at 25 °C from 0.5 Ω to 20 Ω and thermal time constants from 65 s to 240 s. Featuring a diameter of 38 mm and thickness less than 10 mm, these thermistors do the same job as a power resistor and relay, but in a smaller, single-part alternative that saves valuable circuit board space.


The Battery Show is a leading global industry event that covers today’s emerging advanced battery technology for the automotive, portable electronics, medical technology, military and telecommunications, and utility and renewable energy support sectors.
