Battery Safety – The CE Mark
Thursday, 23 June 2022
In the development of battery packs, the focus is often only on technical development. However, this alone does not go far enough. After all, new batteries require various certifications so that they can be placed on the market in compliance with the law. Worldwide, there is a multitude of different rules and regulations concerning the

IEC certification – A common denominator for all continents
Monday, 30 May 2022
The standards of the International Electrotechnical Commission (IEC) are among the most important groups of standards for the certification and safety of electronic products. They include both cells and batteries and span primary cells, secondary cells, battery packs and portable device batteries. In addition to the requirements for the devices and central rules for the

UL certification – the key to the US market
Tuesday, 24 May 2022
The standards in the North American market are set by Underwriter Laboratories (UL). UL is an independent US private company, one of the oldest testing institutes in the world, which published the first standard in 1903. Unlike the IEC/CB method, which does not use a test mark, UL has a test mark and a database

Insights into the daily tasks of a project manager: The first steps in battery development projects
Tuesday, 01 March 2022
In the consumer sector, the decision for the right battery is made quickly. There are standard batteries which fit in consumer applications. However, in the industrial or medical technology sector, the situation is different. For these applications, “off-the-shelf” batteries are often not suitable. There are special requirements concerning safety or space. The solution: individually developed

What is the difference between a Protection Circuit Module (PCM) and a Battery Management System (BMS)?
Tuesday, 16 November 2021
When developing battery packs, the question arises as to which safety system the pack should be equipped with. Is a Protection Circuit Module (PCM) sufficient? Or should a Battery Management System (BMS) be integrated? What are the differences between the mechanisms? And what advantages and functions does which protection mechanism offer? The answer here, as

What actually happens when lithium batteries are over-charged or deep discharged?
Thursday, 14 October 2021
Charging Process: Lithium-batteries are charged with constant current until a voltage of 4.2 V is reached at the cells. Next, the voltage is kept constant, and charging continues for a certain time. The charger then switches off further charging either after a preset time or when a minimum current is reached. In the rare event

What special features are there to consider when designing-in a lithium polymer cell?
Thursday, 02 September 2021
What special features are there to consider when designing-in a lithium polymer cell? An important point, according to battery expert Dr Jürgen Heydecke, is certainly the so-called “swelling”, the natural swelling of a lithium polymer cell in a fully charged state and over cycles. A fully charged cell is thicker than a discharged one. During

The Right Battery for Locking Cylinders and Locking Systems
Wednesday, 25 November 2020
Electronic locking cylinders have long since replaced mechanical locks in many companies. Not the key, but the transponder or key card is granting access to the company building. In private homes, too, the trend is moving towards the electronic lock. Depending on the product and manufacturer, door locks can even be opened by cell phone.
