Why small, low-cost batteries are generally a poor match for highly capable ohmic battery monitoring products?

Nov , 18 2021

The answer isn’t just cost. There are some contrasts between the differing performance expectations and resource environments of two categories of stationary battery system users. It proposes some simple requirements for battery monitoring at cost-constrained sites with modest-sized stationary battery systems and proposes a solution to providing battery health assessment at such sites. Operators o...

Why high performance battery monitoring solutions suit sophisticated users?

Nov , 18 2021

The battery monitoring industry has made a strong case that today’s ohmic battery monitoring systems are effective at discovering battery weakness well in advance of complete failure. Such systems are employed to increase a user’s certainty that stationary batteries will deliver their rated output when needed, thus preventing application downtime. The need for uptime at a credit card processing si...

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...

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...

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...

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...
