Stricter standards for battery tests reduce fire risk

VDE calls for more security for electric vehicles Stricter standards for battery tests reduce fire risk Electric bikes so far, without adequate security checks Frankfurt (ots) - Electric cars can be safer if the testing and approval criteria will be tightened considerably. In particular, the risk of fire in a serious accident is not covered by the currently available tests adequately studied. This was underlined by Wilfried Jäger, Chairman of the Board of the VDE Institute, to the opening of a new battery and environmental test center in Offenbach. Hunter called for new or expanded safety standards not only for cars but for bikes with an electric auxiliary propulsion. Modern lithium-ion batteries have a very high energy density and therefore must be operated in a certain temperature range. Failed to cool in a battery, for example by a short circuit to an accident, threatening the entire overheated battery, in the worst case a fire. The current standards are far from those cases not sufficient. Especially critical is the deviation of actual accidents from those currently prescribed tests. So usually only Quetschtests be carried out where the battery is being slowly squeezed together with a defined force to half. In a real

GE starts mass production of sodium-nickel battery

The U.S. technology giant General Electric has invested 100 million U.S. dollars in a new factory in upstate New York. The plant in Schenectady will employ up to 450 people and new kinds of batteries, which are based on a sodium-nickel-Chemistry, Technology Review reported in its online edition. The current memory should be more durable than conventional lead acid batteries. Main purpose, buffer solutions: Electricity from renewable sources like wind or solar power will thus be cached, to stand by in times of low production.

ADAC test automotive batteries

Manufacturers also sometimes need help starting /
Posttest were: Exide Premium 722 and EA Banner Power Bull
Munich (ots) - After a disastrous test result last year, the ADAC has
now re-tested starter batteries. Two of last year with "poor" rated
batteries have now been improved and have reached the verdict in
post-test "good". Since battery problems are the most common cause of
breakdown, according to the ADAC, manufacturers should not neglect the
quality of spare parts. Especially in winter, the reliability of
automotive batteries for car drivers is essential.
The Exide Premium 722 and the EA banner Power Bull could convince the
posttest. It looked at the startup performance of the batteries. In
addition, the force donors were subjected to technical examination,
which includes, among other things, water consumption and discharge.
Furthermore, the durability (cycle life and corrosion) tested.
Dissatisfied ADAC is still named the starter batteries with respect to
the manufacture date. The date of the turnkey delivery and the
freshness date should be clearly marked and traceable. Also a
recommendation of the inspection intervals should be visible. If
necessary, the battery should also have an indication of the warranty
period and of the coverage.

CTEK Charger for automotive batteries wins Comparison

If at low temperatures, the automotive battery weakens, usually must
be replaced or recharged. There are good chargers for under 100 €, but
it should be left entirely approve of the fingers.
With "highly recommended" the battery charger CTEK MXS has been chosen
by 5.0 Kunzer test winner. It reached GTÜ comparison 452 of 500
maximum possible points, followed by Bosch C3 with 418 points.
Stuttgart / DüsseldorfDas morning organs in cold weather and the lousy
non-starting of the engine knows almost every driver: the nasty
surprise of a dead battery. It is not necessarily due to poor quality
or age of the battery - and it is usually four years - but often
traveled to the city too much short-haul traffic.
To recharge, each battery takes its time, either on an extended tour,
or at the local outlet. It provides the appropriate battery charger
accessories trade that cost less than 100 €. Eight of them, buttoning
the Society for Technical Supervision (GTÜ) before now.
Winner with the title "Highly recommended" was the CTEK MXS 5.0 of
Kunzer, which is commercially available. The MXS 5.0 GTÜ achieved in
comparison 452 of 500 maximum possible points, followed by Bosch C3
with 418 points. The squares were followed (score in brackets) M + S
Intelli 2 (378), Cartrend MP 3800 (368), Saito Pro Charger XL (362),
AEG LP Plus (334), ProTech M42 (310) and far behind the Cartrend 6A
with only 158 points.

Auto - Technology: The car battery checked before winter

Munich (dpa / tnm) - engines last longer, but some car battery makes
tuckered after four years. As pointed out, the ADAC in Munich before
the winter, and recommends a technical review in a specialist
workshop.
Especially older batteries often failed at the first frost in service.
Be first indication if the donor strength even at mild temperatures
have difficulty to operate the starter, the experts explain the ADAC
in Munich. They therefore recommend that before the winter to a
technical review of the car battery in a specialist workshop.

industrial batteries applications

Industrial Applications of Batteries looks at both the applications and the batteries and covers the relevant scientific and technological features. Presenting large batteries for stationary applications, e.g. energy storage, and also batteries for hybrid vehicles or different tools. The important aerospace field is covered both in connection with satellites and space missions. Examples of applications include, telecommunications, uninterruptible power supplies, systems for safety/alarms, car accessories, toll collection, asset tracking systems, medical equipment, and oil drilling.
The first chapter on applications deals with electric and hybrid vehicles. Four chapters are devoted to stationary applications, i.e. energy storage (from the electric grid or solar/wind energy), load levelling, telecommunications, uninterruptible power supplies,
