Supercapacitor applications

Although batteries and supercapacitors both store electrical energy, they do so in very different ways that bestow them with complementary characteristics. In a nutshell, batteries store energy chemically and offer high energy density (measured in Wh/litre) while supercapacitors store energy in electric fields and offer high power density, measured in kW/litre.

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, […]


Battery swapping, and the alternatives

Whether you drive a single battery EV or operate a fleet of them, ensuring there is enough energy in the battery to complete the job in hand is bound to be a major concern (writes Peter Donaldson). The fact that there are different ways of charging, and that many vehicles can use more than one […]


Design unveiled for 800V inverter from Texas Instruments

Texas Instruments has developed a reference design for an 800 V, 11 kW three-level, three-phase inverter using gallium nitride (writes Nick Flaherty). The inverter uses a 6.6 kW active neutral-point clamped (ANPC) inverter design with a 600 V LMG3422R030 GaN FET. This enables a switching frequency of 100 kHz to reduce the size of the […]
