Designed for both commercial and residential use Prism is a new customisable Electric Vehicle (EV) charging station created by Cartender. Starter kits are now available from $245 offering a “definitive open solution for EV charging”, say its creators.
“Prism is the first commercial charging station that offers full, hassle-free control over the entire charging process. Prism offers a higher quality-to-price ratio than other products currently available on the market. And, most importantly, it is the only device of its kind that benefits from the flexibility of an open architecture.”
“Our goal is to give you full control over the process of charging electric vehicles. Prism includes a user-friendly interface, which you can access through your browser or using a mobile app. It provides access to all of the settings you might need to manage the charging process and monitor related information. It also displays usage data and offers real-time control over charging schedule and power. Prism can communicate with other devices and software using standard protocols such as MQTT and OCPP 1.6, or by means of a simple hub-and-spoke configuration.”
Prism offers a wealth of features and is perfect if you currently :
– Have an electric vehicle that lacks the ability to set its own charge limits? Program Prism to stop charging at 75% or whatever fraction of “full” you deem optimal.
– Need an easy way to reconfigure your charger? Record knocking command sequences to trigger customized behavior. Knock on Prism four times to set a charge limit of 80%, for example, or knock once and revert to 100%. Even if you’re wearing gloves and your hands are full of groceries.
– Want your vehicle to draw power only if the rest of your household energy consumption is below a certain threshold? Or to charge only from what you generate through photovoltaics? These are just a few of the ways you can customize Prism.
