How to implement battery monitoring in a deployable product?

Nov , 27 2021

Standalone ohmic battery monitoring systems designed for data center application are not suited for a genset environment. Although ohmic monitors work, they are expensive (estimated at $2,000 for a 24-volt system), time-consuming to install, and require trained personnel to interpret their data output. To achieve widespread adoption in the genset market any battery monitoring technology will need ...

What are the recharge cycles phases of a Lead acid battery?

Nov , 27 2021

The fastest generally accepted way to charge a conventional (lead‐acid or NiCd) battery is with a constant voltage, a current limited battery charger that is capable of both “boost” and “float” output voltages. “Boost” charging applies a higher than normal voltage to the battery early in the charge cycle to charge the battery as quickly as possible. Later, once the battery is charged, charging vol...

What is Thermal runaway and what is its impact on cell chemistry?

Jan , 06 2022

One of the main causes of danger for lithium-ion cells is related to the phenomenon of thermal runaway. This is a healing reaction of the battery in use, caused by the nature of the materials used in the chemistry of the battery. Thermal runaway is mainly caused by the solicitation of batteries under specific conditions, such as overload under adverse climatic conditions. The result of a thermal r...

Three Big Reasons You Should Pair a Home Battery with Solar

Jan , 10 2022

As residential solar installations increase across the country, homeowners are realizing that investing in solar alone won’t benefit them in the long run. The reason is because most solar energy is produced between 9 a.m. and 3 p.m. while (pre COVID-19) you’re probably at work or school. When you return home and start using your electronics and appliances, it’s likely that there isn't enough solar...

3 Reasons to Choose Energy Storage over a Generator during Fire & Hurricane Season: Reason-3

Jan , 10 2022

Past 2 years will stand out in the history books as years that forced us to radically rethink (and adjust) the status quo. As we go into summer, the stability of our utility grid will be put to the test when many of us are spending most of our time at home. Fire season will begin shortly in different places, with utilities sending out messages about public safety power shutoffs. On the...

High Frequency / High Ripple Resonant Chargers: Good or Bad? (part-2)

Jun , 13 2022

Battery charging is a complex electrochemical process, in which the discharged electric energy is replenished from the electric power grid. This is accomplished using a battery charger, which is an electrical/electronic device that converts the incoming AC line voltage into a regulated DC voltage to meet the charging needs of the respective battery. In a series of articles we are going to explain ...

Explore and analyze the thermal power of Li- ion cells and battery packs (part-3)

Jul , 04 2022

1. Influence of ambient temperature: The following figure shows the battery temperature rise curve (average temperature of 5 sampling points) during 1C charge and discharge process of 55Ah battery at ambient temperatures of 20°C, 27°C and 40°C. From the figure, we can It can be seen that the charging time of the battery at 20°C is 74min and the discharge time is...

Power Factor and Harmonic Analysis in PWM converter

Aug , 15 2022

Most of the power conversion applications consist of an AC to DC conversion stage and this DC output is then used for further stages. An AC to DC converter is an integral part of most of the electronic equipment as most of these equipment are DC powered [1]. Generally to convert AC to DC a diode bridge rectifier is used. To reduce the ripple in the output voltage a suitable filter capacitor is use...
