    Warning: Rainbow easter egg on charge port may be harmful to your EVSE

    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...

    Smart EVSE (Open Source)

    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...

    Smart EVSE (Open Source)

    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...

    Feature Request: Charging Multiple Tesla's Simultaneously

    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...

    Feature Request: Charging Multiple Tesla's Simultaneously

    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...

    Feature Request: Charging Multiple Tesla's Simultaneously

    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...

    Feature Request: Charging Multiple Tesla's Simultaneously

    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...

    Feature Request: Charging Multiple Tesla's Simultaneously

    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 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...

    Liquid Sky used the same contactor for the Wattzilla (80A UL listed Charging station based on OpenEVSE components) with a similar driver board. The reason beacuse the contactor is small, cheap and opens super fast... You should be able to drive relay without another board, just modify the value...

    In-development: Inexpensive Custom BMS for Tesla Battery Modules

    These days, I do all my prototyping SMT. Soldering through hole is too tedious. I use solder paste, template, tweasers and an electric skillett. Once you get it figured out small parts are a breeze and boards go together very fast. I built the first ~200 OpenEVSE boards 5 - 10 at a time with...

    Upper Rear Link Build (Reduces rear camber to improve tire wear)

    I was very supprised as well, I did not expect to sell 1000s but at least a couple sets a week... I figured folks wouldn't mind spending a few hundres dollars to save a few thousand. It took almost a year to sell the 18 sets from the first batch and I had to cutting the price to below cost...

    My HPWC almost melted down!!!

    Normal heating (like shown in the graph) is okay, it is the run away heating that is very dangerous. The goal with OpenEVSE testing is to find reasonable set points to reduce current (and heat) when tempratures get to component ratings to ensure no instability. An event like the OP had with...

    My HPWC almost melted down!!!

    This is an area af great interest in the Open Source EVSE community. We are doing a lot of research it temprature monotoring and throtteling. We have implemented several temprature thresholds to reduce current by 25%/50%/75% then shutdown if temps continue to rise. Here is an image of temps...

    First Annual OpenEVSE Steampunk Contest

    OpenEVSE would like to announce the first Annual Steampunk Charging Station Build Off.

    Model S nor responding very well to pilot increases I put the Model S on my OpenEVSE setup to dynamically adjust the pilot based on solar output. Yesterday, I had the Leaf on as the pilot ramped down and it worked great. This morning I put the Tesla on and it started at 9A then ramped up...
