SPECIFICATIONS

The DCC – Electric Vehicle Energy Management System (EVEMS) is a safety device with programmable controller that can protect an electrical distribution circuit in relation with its main breaker. It will prevent overloading the electrical distribution circuit by turning off momentarily the power to the charging station when the demand exceeds 80% of the main breaker rating.

CHARACTERISTICS

CONDITIONS FOR APPLICATION
The DCC-10 is an Energy Management System specially designed to allow the connection of an EV Charger, in a house or dwelling, to an electrical panel that is at full capacity and would otherwise need to have an expensive service upgrade.
MAIN POWER SUPPLY (CB)
The DCC – Electric Vehicle Energy Management System (EVEMS) can be powered by a 240/208V AC single phase source.

The following options are offered by each DCC model:

SECONDARY LOAD SUPPLY (EVC)
The DCC – EVEMS will provide power to a charging station through a 30A, 40A, 50A or 60A 240/208V AC circuit breaker, L1, L2 and ground.
The DCC is equipped with a Square D circuit breaker (QU0230, QU0240, QU0250 or QU0260).

TRIP PERCENTAGE (TP)
The DCC – EVEMS is factory set to turn off the charging station if the total consumption of a service exceeds 80%. For a different configuration, see the “TP” configuration details on page 10 of this manual.

POWER OUTAGE
In the event of a power outage, the DCC – EVEMS automatically restore the power supply to the vehicle charging station when power returns.

RECOVERY TIME (RT)
Following a power cut to the electric vehicle supply equipment (EVSE), a 15 minutes delay is initiated to monitor the total consumption of the electrical power system. Power to the vehicle will then be restored if the total load consumption is lower than 80% of the main circuit breaker rating during a period exceeding the 15 minutes’ recovery time.

CONTROL BY A THIRD PARTY SYSTEM (EMS)
The DCC control board has a dry contact type input (black terminal) to be connected to a building energy management system.

When the contact is:
– Open, the DCC cuts the power to the charging station.
– Closed, the DCC supplies power to the charging station, provided that the main power supply of the DCC is under the only configured current.
The dry contact type output, which reproduces the state of the dry contact input, allows several DCCs to be cascaded on a single control signal.

TYPICAL INSTALLATION

NOTES
NEMA 3R enclosure allows for outdoor installation.

3. Ensure that the mounting is according with the information’s on the enclosure.
4. Fix the DCC with the anchors provided for the type of surface.
5. Check that the DCC is adequately fixed to the wall or ceiling.

STEP 4: CONDUCTOR CONNEXIONS
Consult the diagram on page 10 for all details on the cable connections configuration. This diagram is also found under the DCC cover.

Current transformers (CT) installation and connections

1. Open the CT.
2. Install the CT around the main power cable of the panel.
3. Check the correct polarity on the CTs.
4. Connect the CT cables provided for this purpose to the terminal blocks (green terminal) on the DCC-10 control board.

EXTENSION OF CURRENT TRANSFORMERS’S WIRE
The DCC comes with 20 feet of wire. It is possible to extend the wiring supplied with the current transformers.
Additional wire must be 300V rated, minimum 18 AWG (1mm), 4 conductors shielded twisted (ex: FT4 SHIELD. 4C FAS #18 or equivalent).

STEP 5:
DIP SWITCH PROGRAMMING FOR MAIN POWER SUPPLY

1. Identify the set-up section on the DCC.
2.  Set up the section as per the layout corresponding to the main power supply :

Main power supply

Models| 60A| 70A| 80A| 90A| 100A| 125A| 150A| 200A
---|---|---|---|---|---|---|---|---
DCC-10-30A| | | | | | | |
DCC-10-40A| | | | | | | |
DCC-10-50A| | | | | | | |
DCC-10-60A| | | | | | | |
| | | | | | | |

Note: DCCs do not support configurations in which the charger circuit (EVC value) is greater than half the capacity of the electrical input (CB value). This is why, for example, the combination CB=100A, EVC=60A prevents the DCC from being switched on (flashing red light).
However, it is possible to safely operate the DCC for a 60A charging circuit on a 100A main electrical input using the following configuration that provides a 60% load shedding threshold of 125A, i.e. 75A:

STEP 6 (OPTIONAL): CONNECTION TO A THIRD PARTY ENERGY MANAGEMENT SYSTEM
If a third-party system is to control the DCC, see step 6 at the end of this manual.

If the DCC is not used with a third party system, do not remove the jumper connecting the two terminals of the EMS IN input to create a closed contact.

APPLICATION

Electric vehicle recovery time
Following a power cut to the electric vehicle supply equipment (EVSE), a 15 minutes delay is initiated to monitor the total consumption of the electrical system. Power to the vehicle will then be restored if the power required by the total of the loads is less than 80% of the main circuit breaker and if the control input for the energy management system is in the closed state (closed contact).

Electric vehicle charging time
It is recommended to schedule the charging vehicle program during hours of low electrical consumption to minimize interruptions to the electric charging station.

MAINTENANCE

Do not use any cleaning solvents to clean the DCC.

LIGHTS CODE

| The charging station is energized.
---|---
| The charging station is energized. The total load exceeds 80%. If the loads exceed 80% for a predetermined period, the charging station will be de- energized.
| The charging station is not energized. The total loads exceed 80%. The resumption time will start when the total load is lower than 80%.
| The charging station is not energized. The total load is lower than 80% and the recovery time is in progress. Each flash mean two (2) minutes before the resumption of power to the charging station. (ex: 3 flashes = 6 minutes before power to the charging station). During that period, if the total load exceeds 80%, the recovery time will restart from the beginning.
| Malfunction:
| 1. Check all connections and voltage.
2. Check the DIP switch configuration settings.
3. Check if the current transformers (CT) are properly connected and interlocked.
4. Check if the connection for the current transformers are properly connected to the PCB electronics.
5. If the problem persists, send pictures of the installation at support@rve.ca and then call 1 833-717-1355.
| No power. Check the power source.

STEP 6 (OPTIONAL): CONNECTION TO A THIRD PARTY ENERGY MANAGEMENT SYSTEM

1. If a third-party system is to control the DCC, connect the “EMS IN” input (black terminal) to the “dry contact” output of the third-party energy management system.
2. If required, connect the output (EMS OUT) to the next DCC to be controlled. The recommended cable for the control signal is a twisted copper pair, 18 gauge minimum and 14 gauge if multi-stranded.
3. For the Cristal Controls LS-100 control panel (external power management system recommended), the configuration on the Outputs tab of the configuration software should be as follows:

DCC-9-40)
Min OFF (sec)| 900 sec. This is the minimum amount of time a charger must remain off.
Delay ON| 300 sec. This is the time between the successive activation of two outputs and corresponds to the start-up time of the charger.
Delay OFF| 2 sec.
Cycle delay| 7200 sec (2 hours)
