A quick calculation: To estimate a battery’s internal resistance, you can use a simple voltage-drop method when the open-circuit voltage, loaded voltage, and current draw are known. For example, if a ...

Ametek’s EM Test offers the VDS 200Q Series, a four-quadrant voltage drop simulator that can source and sink current using a programmed voltage in both positive and negative polarities. Ametek's EM ...

Electrical equipment that operates below its voltage rating can overheat or power down. Here's how to determine your load's operating voltage. Voltage drop across switchgear and feeder and branch ...

Measuring rise time for a power source. Voltage vs. time signals measurements via a scope. A practical setup for battery testing. I was recently asked a question about a dc power supply, aka a voltage ...

Battery management encompasses two main functions: 1. Charging adapter, and 2. Battery fuel gauging and protection on the battery side. The block diagram in Figure 1 depicts the overall system. In ...

In hybrid vehicles, a high-voltage battery serves as the primary power source for the electric motor. These components and the electronics that govern them work with the car's internal combustion ...

As a fundamental concept of electronic design, voltage drop ranks highly as one to understand well. I particularly appreciate when industry folks come up with creative ways to get the point across.

Tesla replaced the lead-acid low-voltage battery in its vehicles with a Li-ion counterpart in 2021. However, these batteries used NMC chemistry, thus having a higher voltage of 16 volts. The newer ...

GM has issued a product recall for the 2022 BrightDrop Zevo 600 all-electric delivery van due to an issue related to improper sealing for the vehicle battery pack. The problem: the high-voltage ...
