OpenEVSE history and specifics

What I haven't figured out yet is what type of batteries the OpenEVSE is able to charge (i.e. does it allow charging nickel-iron (NiFe) batteries, deep-cycle batteries, nickel cadmium batteries, ... ? This is an important distinction, since the different types of batteries need different charge rates (voltage and amperage and duration needs to be different).

Since it was intented for the Nissan Leaf (see https://store.openevse.com/pages/about-us ), I think its mainly just useful for charging lithium ion batteries, but I don't know. If the charge rate (voltage and amps, and duration) can be set, it could be suited to charge any battery.

Perhaps more details can be found at http://www.mynissanleaf.com/

OpenEVSE is not a charger itself, it is just a charging access point. The charger is in the car. The only thing that the OpenEVSE does is safely provides the AC power from your electric circuit (i.e. at home) to the car. The on-board charger in the car (usually 10-22kW) will take the AC, talk to the OpenEVSE to see how much power it can safely take, rectify and charge the battery according to the car specifics. OpenEVSE doesn't care. It will also monitor the power and total energy used, can also control when and how fast to charge using simple protocol with the car. OpenEVSE will tell the car to stop charging, disconnect the power, or stop charging and disconnect things, if various fault conditions are detected, or prescribed amount or time passed. It is just a fancy AC switch with some safety features. 2A02:168:F609:0:EB6D:CD88:6E1C:CE80 (talk) 13:52, 3 February 2020 (UTC)[reply]
