Page 4: Introduction
In addition, there are warnings to let you know that error conditions are approaching. One of the important safety features of the EMS is ground fault detection. When an inadvertent connection is made between the battery pack and the vehicle chassis, it is detected and a warning is shown on the screen. - Page 5 M A N U A L microprocessor that is capable of outputting composite video. A CAN interface option is available to display the EMS information on a CAN display. Many options in the EMS are programmable and can be customized for your car.

Page 19: Video Display
M A N U A L Video Display The EMS has at least two pages of information it can display. The first is a summary page which has information for the entire system and then one or more detail pages. - Page 20 E M S O P E R A T I O N A N D I N S T A L L A T I O N M A N U A L gives a precise reading. The graph is green when the voltage is above 3.0V per of maximum, and it changes to red when it is below.
- Page 21 E M S O P E R A T I O N A N D I N S T A L L A T I O N M A N U A L Maximum Cell Voltage is the maximum of the readings of the individual cell voltages. This value is updated after each scan of the individual cells, every 1-2 seconds.

Page 23: Alarms And Warnings
E M S O P E R A T I O N A N D I N S T A L L A T I O N M A N U A L Alarms and Warnings To protect the battery pack, there are a number of alarms and warnings. These are based on Voltage, Current, Temperature and connection ground fault. -

200 mA to drive a relay. In this way, these outputs can signal an alarm when there is an error condition or have the voltage go away when there is an error condition. When power is removed from the EMS computer, the outputs will not supply power. -
Page 25: Battery Balancing
E M S O P E R A T I O N A N D I N S T A L L A T I O N M A N U A L The alarm outputs are located as shown below: Battery Balancing When the cell voltage rises above a predetermined threshold (see specifications for this value), a small current is drawn from it. -
Page 26: Capacity Algorithm
Because the EMS is keeping track of all current in or out of the battery, it must powered at all times. When the EMS first powers up, it sets the capacity to 50% so it will not read correctly until after the first complete charge. -
Page 27: Can Interface
Section 8. CAN Interface A CAN BUS interface is available as an option for the EMS computer. The CAN BUS Interface transmits all the summary information on the main page, alarm status, and the information on the detail page about the sense boards continuously over the BUS, so that a display device can present the data in graphical form. - Page 28 E M S O P E R A T I O N A N D I N S T A L L A T I O N M A N U A L The signals available on the interface are as follows: 12V the 12V input CAN H the normally high CAN signal in the differential pair CAN L the normally low CAN signal in the differential pair...
