How to calculate Solar Payback?

Aug , 31 2021

Solar energy is a rapidly growing industry, thanks to the dramatic drop in prices for solar energy systems in the past decade. In most cases it is more cost effective to implement a solar energy system than to buy electricity from the local utility company. Solar provides predictably priced electricity for 20-30 years, making it easy for businesses to forecast operational expenses. In top of that,...

Lithium battery cycle data analysis with constant voltage charging current and capacity decay curve

Oct , 29 2021

Generally, cycle life testing will generate a lot of data, which can obtain a lot of information. What analysis and processing can we do with these cycle data? The following summarizes some of the data processing, continuation from last week’s article. 1. Constant voltage charging current and time Lithium-ion batteries are usually discharged at different currents during use, and often cannot under...

Implementing a useful battery assessment system at low cost

Nov , 22 2021

In the battery system industry, some companies provide charger and battery systems to smaller, mission-critical applications; for some years, it has been clear that reducing the impact of battery failure is the best way to increase the user’s overall system reliability. In contrast to power electronics that can achieve MTBF in the range of 1 million hours, all VRLA batteries will fail between “now...

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 the right duration of Phase 2 of a charging cycle?

Nov , 27 2021

The duration of Phase 1 is determined by the battery’s depth of discharge, the ratio of charger ampacity to battery capacity, and whether there are parasitic DC loads connected to the system. Although the duration of Phase 1 does vary, we are not concerned with this variation since, once the battery capacity, charger output, and DC loads are installed, we have no means to change the duration of Ph...

What is Dynamic Boost and how does it works?

Dec , 03 2021

As with the current‐controlled automatic boost system, Dynamic Boost includes no pre‐programmed boost timer. Unlike the current‐controlled automatic boost system, however, Dynamic Boost automatically adjusts boost duration to take into account differing parasitic DC loads and other variables discussed above. The principle behind Dynamic Boost is simple and straightforward. Refer back to Figure 1. ...

Why flooded SLI batteries in GENSET applications fail sooner and more suddenly than in vehicle applications?

Dec , 06 2021

Continuous float charging flooded SLI batteries accelerates the deterioration of polyethylene plate separators to a life shorter than that which battery designers intended. When subjected to continuous float charging, the dominant and earliest failure mode tends to be premature failure of the polyethylene separator. Separator failure typically results in short circuits that prevent the battery fro...
