CPIM1000 Integrated Meter Guide

RISK OF SHOCK. Before working with this equipment, disconnect the power to the CPIM1000 Integrated Meter. Follow standard practice and local code to de-energize the applicable circuit and lock out/tag out the disconnect before proceeding. Use a multimeter to test that power is off. Keep power off for this circuit until the work scope is completed. FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN SERIOUS INJURY OR LOSS OF LIFE.
You must be a licensed electrician and complete online training to become a ChargePoint certified installer, and to get a login for ChargePoint. If you do not complete this training, you will be unable to complete the installation process.
To complete online training and become a certified installer, refer to ChargePoint University at: https://www.chargepoint.com/partners/training-certification.
Do not use power tools during installation or servicing. Over-torquing can damage the equipment.
Do not install or service the charging station in inclement weather. If you work in snow, rain, or wind, you must use a weather-proof shelter that covers all boxes and components.
The CPIM1000 is not repairable in the field and does not contain any user-serviceable parts. In case of any error, the CPIM1000 opens internal relays and interrupts the flow of energy.

CPIM1000 Integrated Meter

The CPIM1000 Integrated Meter is a multifunctional meter intended for use in the field of e-mobility. It uses a backlit LCD to communicate cumulative active energy and two LED pulse outputs to communicate energy steps. The CPIM1000 contains two AC meters, each with its own measuring unit measuring active energy. Accordingly, the display shows two cumulative energies and there is one pulse LED on each side, left and right. The complete device is supplied by the L1-N Input on the right side (top view). If this supply is not provided, the built-in relays remain open and a current flow is not possible.

Installation

The CPIM1000 Integrated Meter is built into CP6000 charging stations. The meter slides downward into the station pedestal housing and connects to a power plate. The meter connects to the power plate with plug-in connectors. User seals must be applied on the connection surface from the power plate to the meter. The left and right side output connectors with attached cables are plugged in and secured. User seals must also be applied on the output connector screws.

Metering Logic

CPIM1000 Integrated Meter current is measured using a current transformer and is transmitted through an A/D converter to a micro controller. Voltage is measured using a ground referenced measurement before it is transformed to a micro controller.

The sample rate is 3.90625 kHz and the energy update rate is 2x mains rate (100 Hz or EU, 120 Hz for US). At sample rate, V*I is accumulated, at energy update rate, the accumulated V*I values are converted to energy.

Fault Detection

In "meter mode" the operating faults have no affect on operations. The only faults that will prevent operation are those that occur on start up:

  • Failure to exit boot loader, generally caused by a bad code image loaded into flash. The LCD displays "-CHARGEPOIN+".

  • Initializing, caused by a MCP3914 failure. The unit will not transfer energy.

If these failures do occur, the meter must be disconnected from the main power supply by a certified ChargePoint technician. The hardware needs to be replaced.

Data Protection

The energy data is computed and stored inside the STM32G4xx micro controller. The micro controller does not provide a mechanism for accessing this data other than via the meter firmware. The meter firmware does not provide a mechanism for updating the energy data from an external interface. The meter firmware can be updated during production or if the seal is removed, but a secure boot mechanism is used to prevent unsigned and unauthorized firmware.

Components of the CP6000 have self destructive tamper proof labels applied by the manufacturer in several locations (a) and (b). Components of the CP6000 also have self destructive tamper proof labels applied by users in some locations (c) (optional).
