Charging

Electric vehicle chargers installed in the UK after the end of 2027, along with heat pumps and grid-connected domestic storage batteries, will have to be remotely controllable by power companies. This is according to the UK government’s response to its 2024 public consultation on ‘energy smart appliances’ (ESAs), which has just been published. “The government will, subject to Parliamentary approval, ...

Vishay Intertechnology is aiming at industrial, medical and consumer wireless charging up to 30W with a range of transmit and receive powdered iron wireless charging coils, optimised for relative humidity up to 90%. Operation is at up to +105°C, and the company is claiming smaller footprints than its previous-generation devices. “The high moisture resistance of the devices results from their ...

Laurent Cordonnier has joined Breathe Battery Technologies as chief financial officer. Breathe is a supplier of adaptive charging software for batteries, with Volvo Cars as its most recent customer. Testing, said Breathe, indicates that its algorithms will reduce electric Volvo charge time by 15-30% between 10 to 80% state-of-charge, while maintaining the same energy density and range. Cordonnier has joined Breathe ...

Omron is aiming at electric vehicle chargers and solar photovoltaic installations by adding a low contact resistance model to its two-pole single-throw G7L-2A-X series of PCB-mount relays. G7L-2A-X-SI has 10mΩ maximum contact resistance, compared with 100mΩ maximum for existing members of the family. Nominal rating is 30A at 600Vdc, or 25A at 1000Vdc (but see below). Versions with 12V (190mA ...

Advanced Linear Devices has introduced an IC that will balance four supercapacitors connected in series – to help prevent any of them being damaged by over-volting as they charge. Like other balance ICs in the company’s range, it does not use op-amps and a voltage reference. Instead it has four precision-trimmed mosfets that act as shunt regulators when connected gate-to-drain. ...

Onsemi has announced three silicon carbide power modules for 800V 11 – 22kW on-board charging and high-voltage dc-dc converiosn in electric vehicles  – all in transfer moulded packaging, claimed to be a first. “Our modules employ the latest SiC technology to minimise losses and overall system volume, allowing designers to meet charging efficiency and space goals,”, claimed Onsemi general manager ...

Researchers at Stanford University have modelled over-night home charging of electric vehicles and predict that it is not the correct strategy, for the Western US at least. Simulation is based on a model, revealed in March, for charging demand that can be applied to different human populations under different conditions. In a demonstration, they have now applied it to the ...

Penn State university is claiming to be able to charge a Li-ion electric vehicle battery in 10 minutes

Cheltenham-based design company Duku has developed a pop-up electric vehicle charge point, claiming it to be a world first. Six of them are on trial in Oxford. A pop-up design was adopted to reduce street clutter, but the amount of historical architecture and utilities under Oxford pavements meant minimal available underground space. “It’s an absolute mess below the pavement in many ...

AMS has developed a pair of chips that can transfer charging current and data simultaneously over the same pair of wires – intended as an interface for wireless earbud charging. The interface, branded Pow:Com, supplies 5V at up to 150mA for charging and data at 1kbit/s. AS3442 is aimed at the charger cradle (WL-CSP16 package). It includes: Pow:Com interface to AS3447 I2C ...
