Automotive & EV Battery Testing
More flexible testing technology for electric vehicles
Battery-powered consumer vehicles have gotten a lot of press lately, but that’s not the whole story. Manufacturers are working equally hard on electrifying commercial and industrial vehicles, and automotive electronics continues to evolve. Automotive electronics used to be focused on entertainment, navigation and comfort systems. Now the focus is on electric drive trains and energy management systems, and this means that test engineers have to be concerned with higher power and higher voltages. Perhaps the biggest challenge that automotive test engineers face is how to keep up with the changing test requirements, while at the same time, avoid buying new test equipment every few months.
To do this, they need flexible test equipment. EA Elektro-Automatik’s line of DC power supplies, electronic loads, and bidirectional power supplies all have features that allow them to test today’s designs and still meet future needs. EA’s PSI, EL, ELR, and PSB product series can output up to 2000 V, have true autoranging, and on-board arbitrary waveform and function generators. These features allow EA instruments to produce or sink power as needed to simulate real-world conditions and test any power device in an electric vehicle.

Fuel Cells, Batteries, and Battery Management System Testing
EA Advantages
Reliability is a key concern for automotive engineers and especially for designers of commercial and industrial EVs. With that in mind, it is imperative that batteries and fuel cells are tested by simulating real world conditions. Starts, stops, rush hour traffic in 100 degree heat with air conditioning set on high are all situations the EV will encounter on the road, and automotive test standards require the ability to recreate these conditions.
The built-in function and arbitrary waveform generator in EA’s DC power supplies, electronic loads, and bidirectional DC supplies simplifies the process of simulating real-world driving conditions. EA’s instruments also have built-in battery test functionality that can automatically charge or discharge a battery. The bidirectional capability of EA’s PSB series can accurately simulate a battery to test battery management systems without having to wait for a battery to charge or discharge to a specific state of charge.
