C.E. Niehoff & Co. is a privately held U.S. company and leader in the design and manufacture of heavy-duty brushless alternators. Our alternators are designed with the most demanding applications in mind to minimize downtime and maximize your operating efficiencies.
Featured Product
Lithium-Ion Charging
With ever-changing current and future power demands, C.E. Niehoff & Co. (CEN) has developed charging solutions to meet these challenges. We offer solutions for most alternate battery chemistries, including lithium-ion, where specific characteristics are required to perform at a high standard.
Our patented Li-ion charging algorithm features a proprietary current limiting technique rather than directly lowering voltage. We do this to offset the risk of alternator shutdown during battery open circuit voltage (OCV). Furthermore, the system also provides transportability state of charge (SOC) management, and batteryless management is maintained by implementing voltage filters*.
Data drives performance in almost every application, and CEN solutions gather critical information needed for Li-ion charging. For example, utilizing either J1939 or Smart Battery Sensor* to communicate with the battery, our units keep track of battery terminal voltage, current, maximum charging current vs. temperature/SOC, optional battery SOC and battery “contactor” state.

*In military applications, the batteries must comply with MIL-PRF-32565 Rev B or later to use CEN’s Plug and Play charging solutions for up to 16 Li-Ion batteries connected in parallel.

Made in the U.S.A.
All of our products are designed in house and proudly manufactured on our campus in Evanston, Illinois. We look forward to the opportunity to serve you with the same philosophy and commitment to quality which has become the foundation of our business.
Made for You
Models are customized for niche markets with a wide range of output capabilities and a variety of market specific features. Units are designed to withstand chaff, dust and corrosive agents of agriculture, construction, marine and mining environments. Our brushless design eliminates internal arcing making it ideal for operation in volatile environments. The high efficiency of our unique design requires less engine horsepower and fuel to produce the high output required in the emergency vehicle, rail, transit, and military markets.
