BASF Schwarzheide has installed a 1MW 5.8MWh sodium-sulphur battery to increase the amount of energy it can use from the solar park at its manufacturing site in Lusatia Germany, where it produces electric vehicle battery materials. “The stationary energy storage system is another step towards increased sustainability in battery production for electric vehicles,” said company v-p of battery metals Daniel ...

Weidmuller has announced a series of battery connectors and battery connector cable assemblies. They are “engineered to handle high currents” and “designed to withstand harsh environmental conditions”, according to the company. Connectors for cables from 16 to 95mm2 are available, with contacts made from copper alloy finished with silver and, approved according to UL 4128. Predicted mechanical connection life, without ...

The choice of battery for an application is critical. It affects the bill of materials and product lifetime cost, says Björn Rosqvist. Consider a battery-powered remote sensor. The cost of its battery is usually small compared with the overall product cost, but then think about the cost of replacing that battery. For wireless sensors deployed in remote areas, used for ...

NGK Insulators has teamed up with Rohm to produce a complete energy storage evaluation kit for IoT devices including shelf-edge labels. Called REFLVBMS001-EVK-001, it measures 56 x 32 x 1.6mm and the components, including the battery, stand a maximum of 1mm above the PCB. It can accept power at 4.5 to 5.5V, and outputs up to 500mA at one of ...

Custom lithium battery pack maker Alexander Battery Technologies has installed “the world’s most advanced laser welding machine”, it said, at its factory in Peterlee, UK. “The EV Flex laser welder uses machine vision and configurable optics to produce micrometer-accurate welds between the terminals on a battery cell and busbar,” according to the company. “Employing optical laser depth detection, the EV ...

Littelfuse has invented an AEC-Q200-qualified temperature monitoring tape for electric vehicle batteries. Branded TTape, it detects local over-heating via thermally sensitive spots spaced along its length, all connected in series. The spots are positive temperature coefficient thermistors. “Distinguishing itself from NTCs [negative temperature coefficient thermistors], the profound advantage of localised cell overheating detection ensures quicker alerts to the battery management ...

Microsoft and the US Pacific Northwest National Laboratory (PNNL) have teamed up in a multi-year project to explore material science using AI and super-computing, and discovered a promising solid electrolyte for lithium-ion and sodium-ion batteries as a proof-of-concept. The multi-step process used to search for possible electrolytes reduced a list of 32 million inorganic materials to 18 in 80 hours, ...

For grid-scale energy storage, the search is on for durable batteries made from low-cost materials. Aqueous zinc-iron batteries are one suggestion, where storage is though the reversible plating and stripping of zinc at the anode. One of the problems associated with this chemistry (dendrite growth is another) is hydrogen gas generation from parasitic side-reactions that decompose water – which gradually ...

E-peas has created a power IC that can mediate between two energy harvesters, a 5V charger, a power store and a load. AEM13920 can work from any combination of two sources including: photo-voltaic cells, thermo-electric generators, RF energy harvesters or kinetic pulsed sources. “For instance, a remote control could have separate PV cells on its front and rear, to maintain ...

Yamaichi Electronics has added optional CPA (connector position assurance) to its automotive Y-Lock Pullforce board-to-cable connectors for battery management and cell contacting. Found in Y-Lock Version 4, the CPA is located on the stiffener side and latches with the connector when actuated. “The FFC-FPC can only be released after the CPA has been unlocked,” according to the company. “The v4 ...
