The Calex / [https://greenwattpower.com/product/1300-watt-evc-li-ion-charger-series/ GreenWattPower EVC-116-1300] and [https://greenwattpower.com/product/720-evc-li-ion-charger-series/ EVC-116-720] are used as onboard chargers for modern Zero models (2014 onwards except for the 2014FX) and are CANBus-controllable which eliminates the CCU board.

;Design
: The board is a solid-state switching power supply with a CAN interface.
: The aluminum enclosure is well-sealed with over two dozen fasteners.
: The enclosure is filled with a solid rubbery [[Potting|potting]] material.

;Reliability
: Certain model years (MY14 and MY15) have had onboard charger faults after 900-1200 miles and require replacement under warrantee.
: MY16 onward (and MY13 which used Meanwell units) appear to have a lower defect rate.
: This appears to be a third-party quality issue with Calex that was reportedly resolved by early 2016, but this is not proven perfectly yet.
: 720W chargers used on X models appear to be more reliable than 1300W chargers used on S models.

;Design Revision
: In response to the 2014-2015 reliability difficulties, it seems that the internal board was mainly reworked for lower risk of overheating.
: One observation is that the size of the board changed from about ⅓ of the volume of the enclosure to the full area of the enclosure.
: Newer revisions seem to have a cube-shaped clip-on ferrite bead EMI filter on the AC input cable (per [http://electricmotorcycleforum.com/boards/index.php?topic=9049.msg77958#msg77958 this EMF thread]).

;Repair
: Because of the solid rubbery potting, repair of anything beyond the connectors is almost totally impractical, especially given the cost of replacement.
: The board is designed for blind [[Calex Charger Replacement|replacement]].
