Charger BMS GCAN Installation Guide
1 – SAFETY PRECAUTIONS – READ BEFORE USING
The following safety precautions must be read and observed.
• The ground support equipment (GSE) controller area network (CAN) (GCAN) board is designed with
the safety of the user as the highest priority.
• The GCAN board design is such that the installer can safely install it.
• Installation must comply with all local codes.
• The GCAN board supports safe operation of basic charging functions by a user.
1.1 – Symbol Usage
Take special note of the information in this manual marked with the following symbol.
DANGER
Indicates information about safety practices which, if not followed, may result in death or
serious injury.
2 – GENERAL INFORMATION
2.1 – Document Purpose
The GCAN Installation Guide is intended to provide a production technician with the information and guidance
necessary to install the GCAN board safely onto the GSE control board.
2.2 – GCAN Board
2.2.1 – Description
The ground support equipment (GSE) controller area network (CAN) (GCAN) board is an add-on circuit board that
can be added to the 08067 GSE control board. (All boards are in the power station of the chargers.) The GCAN
board is conformal-coated1similarly to the 08067 GSE control board.
2.2.2 – Purpose
The GCAN board enables the charger communication (comm) lines to get charger information from the battery
information management system (BMS)2via he IPC charger CAN communication protocol. If the GCAN board
detects CAN communication, the charger switches into CAN control mode. If the GCAN board does not detect
CAN communication, the charger uses BMID control mode. This allows the charger to be fully backwards
compatible with existing batteries at the customer site.
1Conformal coating material is a thin polymeric lm that conforms to the contours of a printed circuit board to protect the board
components (Wikipedia).
2BMS controls the charging process and the charger.
3The GCAN board supports both the IPC charger CAN communication protocol and the Chinese recommended national standard
(GB/T) communication protocol.

Charger BMS GCAN Installation Guide
2.2.3 – Scope
The GCAN board can be used in all GSE chargers, which include DVS300, DVS330, DVS400, MVS, and the
power station.
2.2.4 – Use Case
If a customer plugs a charger into a truck, then the charger automatically detects whether the truck is using
CAN communication and begins charging using the IPC Charger CAN communication protocol.
2.2.5 – Equipment
Equipment Description Quantity Part Number Notes
GCAN package 1 29974
The GCAN package contains the GCAN board 29974 and a ribbon cable (Figure 1).

2.3 – GSE Charger Decal
A GCAN decal (sticker) indicating that the GSE charger is CAN compatible is adhered to the front-panel door
of the charger, on the bottom-right corner near the screws (Figure 2).

3 – GCAN BOARD INSTALLATION PROCESS
A technician should install the GCAN board. Installation must comply with the provisions of all local electrical codes
in the country of installation. The following sections walk technicians through a ve-step installation process.
Step 1
3.1 – Updating the Charger Software Version
3.1.1 – Update the charger software to version 1.015 or later, using the charger tools software. Contact your
local PosiCharge service representative for a copy of the latest software version.
Step 2
3.2 – Powering OFF the GSE Charger
3.2.1 – Power OFF the GSE Charger before installation.
DANGER – RISK OF SHOCK
DANGER – ELECTRIC SHOCK CAN KILL
The GSE charger needs to be powered OFF during installation. Do not restore power to
the charger until the installation is complete. Failure to follow these instructions could result
in shock or electrocution.
• Touching live electrical parts can cause fatal shocks or severe burns.
• The battery terminals are always electrically live, and the output circuit is live
whenever the battery is connected or being charged.
• The input power circuitry and internal circuits are live whenever input power is ON.
• An incorrectly installed or improperly grounded charger is a hazard.
Step 1 – Updating the Charger Software Version
Step 2 – Powering OFF the GSE Charger
Step 3 – Installing the GCAN Board
Step 4 – Conguring the DIP Switches
Step 5 – Powering the GSE Charger Back ON

Step 3
3.3 – Installing the GCAN Board
3.3.1 – Remove the P6 and P7 connectors from the BMID A and BMID B ports on the GSE control board 08067
(Figure 3).

3.3.2 – Connect the GCAN board connectors on the board back (Figure 4) to the BMID A and BMID B ports on
the GSE control board as shown below and on the next page (Figures 4 – 7).

3.3.3 – Connect the GCAN board ribbon cable connector to the GCAN board ribbon cable port (Figure
8, A) and the P25 ribbon cable connector to the P25 ribbon cable port (to the 5VDC6supply) (Figure 8,
B) on the GSE control board.

3.3.4 – Connect the P6 and P7 cables on the GSE control board to the corresponding ports on the
GCAN board (Figure 9).
Figure 9 P6 and P7 Cables on the GSE Control Board Connected
to the Corresponding Ports on the GCAN Board
The GCAN board is placed between the comm cables and the GSE control board. If the charger is powered
ON, the GCAN board detects when a BMS charger using CAN communication is connected to the comm lines.
The GCAN board uses CAN protocols to get charging information from the BMS. The GCAN board then uses
SG commands to pass that information to the GSE control board.
