OpenEVSE supports charging station based timers. If you are handy you can re-use the cables from the Blink, alternatively ready to go OpenEVSE charging stations are now available. OpenEVSE Deluxe Kit OpenEVSE 40A Advanced

The J1772 spec requires the vehicle to stop pulling current within 100ms on a proximity event, disconnection of power is not required until the pilot signal moves from State C (6v) to State B (9v) or is lost completely. On a proximity event some EVs like the Leaf keep the pilot at State C and...

Maybe one day the rest of the closed charging station market will catch up with SmartEVSE and OpenEVSE. Adaptive Smart Charging is absolutely the future of both home and large scale deployments and the key to reducing infrastructure cost. All versions of OpenEVSE support locking type 2 with a...

I am sorry to hear you moved away from OpenEVSE. OpenEVSE is in fact designed for the international markets and does support locking of a Type 2 socket (with an inexpensive driver board) and proximity pilot for IEC cable ampacity detection. OpenEVSE outputs the commands for Lock/Unlock on the...

Here is another example... OpenEVSE has a Temperature Monitoring and Throttling feature, if the internal temperature of the charging station gets too hot the charge rate is reduced. If the temperature continues to rise the charge rate will drop several times before completely shutting down...

The SAE J1772 specification requires vehicles to respond to a pilot change within 5 seconds. A while back I did an experiment to dynamically change the charge rate based on the output of a solar array. The Model S responded appropriately to pilot changes. At a below 1.2Kw Production OpenEVSE...

It looks like the hjespers/teslams does not have a method to reduce charging current so I do not think it will work. I have been logging the data from my Eagle Gateway on the OpenEVSE Energy Monitoring Portal. The Graph Below depicts total usage and production (5.8kw Solar) from the main...

My 2012 is at 94,500...

Current allocation starts out at 50%/50% but is continuously measured and reallocated as current is available. For example a Volt capable of 16A and a Tesla with twin chargers.... First Vehicle to plug in - would get 80A. Second vehicle plugs in - would change pilots to 40A/40A. After...

I downloaded the python library Eagle_Http_API and wrote the following code:

The Wattzilla Powershare uses a single 100A circuit to share between 2 80A outputs. The 2 controllers internally are tied together with a serial link to coordinate current allocation and report back usage. Liquid Sky certified their products through UL with the OpenEVSE RAPI communication...

I have all the mechanics working in python... I also have a Rainforest Eagle Gateway reading my main meter. Pull data from the Eagle with EAGLE-HTTP-API Read current draw from 2x OpenEVSE Charging stations via WiFi Send OpenEVSE RAPI commands via WiFi to dynamicly change pilot It is not...

There are several similar efforts to this going on in the OpenEVSE community. At Caltech in Pasadena there are 50+ stations going in, these stations share a pool of available energy and dynamically allocate capacity as needed...

I have had so many issues with mine pano since 2012. My first visit to a SC was on Day 5 of ownership beacuse the pano was getting stuck. I have also had lots of creeks, squeeks, shuddering and whistleing noise. The headliner cutout around the edge is also sloppy and uneven (looks like it was...

Alert... Set suspension to VERY HIGH when approching/exiting the Needles Supercharger. The driveway does not look bad but the geometry is perfect, ripped my lower bumper and defuser right off. All the screwtabs shered off. I was able to press the lower bumper back on to make it home. The...
