Wax works well for conducting heat

Researchers in the US and China have developed an economic but efficient battery thermal management strategy using paraffin wax (writes Nick Flaherty). The 3D, interconnected, thermally conductive boron nitride network greatly improves thermal conductivity compared to random distribution. “We designed a 3D network of boron nitride, and systematically studied its effect on the thermal management […]

AGRO explains importance of EMC-shielded cable glands

Like most small parts in complex vehicle systems, the glands that support, seal and protect the interfaces between HV cables and the components they link rarely receive the attention that the critical nature of the functions they fulfil perhaps ought to command (writes Peter Donaldson). AGRO’s EVolution EMC cable glands are a case in point, […]

Green-G ecarry

We investigate this custom-built EV for collecting refuse in the narrow streets of older town and cities The dangers of excess CO2, NOX and other greenhouse gases from refuse and freight trucks in populated urban centres makes it imperative to electrify such traditionally diesel-hungry vehicles.

Components keep their cool in 3D

A feasibility study has examined the use of over-moulding to create 3D electronic components with high thermal conductivity (writes Nick Flaherty). The project, at Sobaplast in Germany, uses the Keratherm MT 103 and MT 320 injection moulding materials from Kerafol on circuit board samples at temperatures that did not compromise the components on the board […]

Battery Show Europe 2021

Fire department Peter Donaldson reports with highlights of this show, at which ways of containing thermal runaway were at the fore If there was one theme that shone out from conversations at the Battery Show Europe and the co-located Electric & Hybrid Vehicle Technology Expo, which took place in Stuttgart late last year, it was […]

Cool SiC inverters move

Researchers at the US National Renewable Energy Laboratory (NREL) have been working with heavy-duty equipment maker John Deere on a new thermal management system for SiC inverters (writes Nick Flaherty). Equipment such as trucks and construction machines account for 39% of greenhouse gas emissions in the transportation sector, so there has been a focus on […]

Webasto swappable batteries power Staad electrified excavators

With many European cities now insisting that machinery such as excavators used on construction sites must not produce harmful emissions, the pressure on the industry to electrify them is growing (writes Peter Donaldson). In 2020, Staad, the Dutch importer of Doosan machinery, formed its Electric Construction Equipment (ECE) division to convert excavators and now offers […]

Dow launches conformal coating for harsh environments

Dow has unveiled a new conformal coating it calls Dowsil CC-2588. It is an abrasion-resistant silicone-based material that protects PCBs and electronic components against high humidity and corrosion. The coating is virtually odourless and cures at room temperature. It can be sprayed on in a single pass and dries to a film thickness of 50-200 […]

Tesla Octovalve analysis

It’s not often that we get the opportunity to dig into the details of an important EV subsystem from the point of view of an independent engineering team, but that is what Cory Steuben of Munro & Associates provided at the recent Battery Show and EV Tech online event (writes Peter Donaldson). The subsystem was the Tesla Model Y’s heat pump, in particular...
