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. ...

Shortcomings of automatic boost timers (Method C) and current‐sensing automatic systems (Method D)
Nov , 27 2021
In the automatic timer control scheme, the duration of the boost charger is pre‐programmed into the charger’s control system. Chargers equipped with automatic boost timers may, under very specific circumstances, provide just the right duration of boost charging. Under all other circumstances, however, such as a different depth of discharge, or when the connected DC load changes, the pre‐programmed...

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 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...

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 type of Battery assessment is suited for GENSET applications?
Nov , 27 2021
Lead-acid battery monitoring technology has matured to the point where the IEEE issued a standard (IEEE 1491) in 2005 to describe the various battery health assessment methods. Most large data centers, for example, spend tens of thousands of dollars for battery monitoring equipment designed to predict whether their UPS batteries will work. Data centers with downtime costs of six figures per minute...

Assuming zero manufacturing defects, what are the chief causes of battery failure for a generator start application?
Nov , 22 2021
Assuming zero manufacturing defects, there are three chief causes of battery failure: Failure to start is the most significant avoidable cause of diesel generator malfunction. Over 80% of failures to start are caused by battery problems. Genset customers invest significant amounts of money purchasing and maintaining generators. Yet the Achilles heel of these large, costly machines is a commodity p...

Genset failure to start: The big problem no one talks about
Nov , 22 2021
Failure to start is the most significant avoidable cause of diesel generator malfunction. Over 80% of failures to start are caused by battery problems. Genset customers invest significant amounts of money purchasing and maintaining generators. Yet the Achilles heel of these large, costly machines is a commodity product little changed since its invention in the late 1800s. Today most gensets do not...

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...
