Plug-Side Chat: Erratic Charging Providers and Single Points of Failure

ChargePoint recently took most of their California Energy Commission funded sites offline with no forewarning. This essentially shutdown EV travel on I-5 for nearly the entire length of California. Several owners were stuck spending hours using Level 2 AC charging in order to salvage their trips.

This is concerning for two reasons. First, we need charging providers to communicate any planned outages or upgrades ahead of time. Second, we need to ensure that these routes are supported by more than just a single charging provider.

Yosta Livepor 100 Review – Yosta go down the single battery road

The Yosta Livepor 100 is a bit of departure from the normal dual batter lightweight mods that Yosta have released in the past. The Yosta Livepor 100 is a single 18650/20/21700 based mod that instead of the usually injected plastic shell…has a metal shell instead.

High Efficiency Bridgeless Single Power Conversion Battery Charger for Light Electric Vehicles

High Efficiency Bridgeless Single Power Conversion Battery Charger for Light Electric Vehicles

Charging batteries of light electric vehicles require chargers with high efficiency and a high power factor. To meet this need, this paper presents a bridgeless single-power-conversion battery charger composed of an isolated step-up ac-dc converter with a series-resonance circuit. The bridgeless configuration reduces the conduction losses associated with the input diode rectifier, and the series-resonance circuit reduces the reverse-recovery losses of the output diodes by providing zero-current switching. In addition, direct and series-resonance current injections enable bidirectional core excitation by the transformer, thereby allowing high-power capability. The control algorithm derived from feedback linearization is also developed, which allows the proposed charger to correct the power factor and regulate the output power in a single-stage power conversion. This simple circuit structure leads to high efficiency and a high power factor. The theoretical concepts of the proposed charger are verified experimentally using a 1.7-kW prototype.
