Modular plug-and-play rectifier

OmniOn Power has developed a modular 30 kW rectifier in a 19 in rack format to build EV fast chargers (writes Nick Flaherty). The EV100H3NK and EV101H3N1K AC-DC variants of the rectifier design have efficiencies of up to 96% and integrate CAN automotive comms protocols. Up to 12 rectifiers can be used in parallel in a 19 in rack to build fast-charging 360 kW systems quickly and easily.

Lotus launches EV charging solutions

Lotus has launched its own EV charging solutions including an ultra-fast DC charger, power cabinet and a modular unit for charging up to four vehicles at once. The EV charging solutions include a liquid-cooled all-in-one DC charger that offers charging of up to 450 kW. For example, with the Lotus Eletre R, it can add up to 88.5 miles or 142 km of range after about 5 minutes of charge. A 10-80% charge can be achieved in 20 minutes to give a range extension of 74 miles or 120 km from a 5 minute charge.

CSM’s new HV breakout module

As an extension of the HV Breakout Module (HV BM) product portfolio, CSM GmbH presents the HV Breakout Module 3.1 OBC for worldwide analyses of the AC charging processes of electric and hybrid vehicles. For this reason, the module is designed for currents of up to 88 Arms (±125 A). Due to the integrated star connection, one- to three-phase measurements are possible with this HV-safe (per EN 61010) measurement module. A high sampling rate also provides precise measurements during switch-on and switch-off processes.

StoreDot warns industry over extreme fast charging battery technology

Extreme fast charging (XFC) battery technology developer StoreDot is reiterating its policy of supplying chemistries that ensure minimal battery degradation over an EV’s lifetime. Its announcement is in response to recent industry claims touting fast charge times and extended ranges, which it says often overlook the potential long-term impact on battery health and the resulting degradation in vehicle driving range.

Thyristors save space in charger

Littelfuse has developed a reference design for a 2 MW bidirectional fast charger for commercial vehicles (writes Nick Flaherty). Rather than using MOSFETs, the 12-pulse thyristor stack can support a 2 MW output in a smaller volume with just forced-air cooling. Five 70 kW modules using thyristors that are stacked to provide 350 kW occupy 0.175m³, excluding any pumps and radiators needed for cooling the circuit. For a dual 350 kW charger, the minimum space consumed is a cube with 1.5 m sides and a volume of 3.4m³.
