Engine Control
Engine control is turned on if the “Auto Start” function is enabled from the remote control by pressing
and holding the two enable keys for three seconds (see illustration of remote on page 4).
Engine control is based on the battery SOC estimated from the battery monitoring module, the battery
charging current, and some predefined parameters that are outlined in Table 2. These engine control
parameters can be configured via Vanner‟s CAN interface software. Please reference the Vanner
CAN Interface User Manual which is available at http://www.vanner.com/vp/manuals.htm.

Description
1
SOC_EngineOn
SOC setpoint to turn on engine
2
SOC_EngineOff
SOC setpoint to turn off engine
3
SOC_LoadOff
SOC setpoint to turn off all loads
4
TopOffChargeEnable
Top off charge enable control
5
TopOffChargeCycles
Number of charge/discharge cycles to top off charge
6
AltMaxVoltage
Maximum alternator voltage
7
FastIdleCurrent
Charging current setpoint for fast idle control
When “Auto Start” is enabled, the engine control logic is as follows;
 If battery SOCach < SOC_EngineOn then start engine.
 If battery SOC > SOC_EngineOff then stop engine.
 Every TopOffChargeCycles charge/discharge cycle allows a top off charge (100% SOC, or 2
hours beyond SOC_EngineOff) if TopOffChargeEnable is enabled.
 If the average charge current is less than FastIdleCurrent and alternator voltage is 0.5V lower
than AltMaxVoltage then fast idle is enabled.
 If alternator is > 0.5V below AltMaxVoltage at full voltage and charge current is lower than
FastIdleCurrent then fast idle is disabled unless that results in low charge current.
When Auto Start is enabled, the time to turn on the engine is also estimated by the battery monitoring
subroutine. The number of charge/discharge cycles before the next top off charge is also updated.
Load Control Parameters
Table 3 lists several load control parameters that can be configured via Vanner‟s CAN interface
software. Please reference the Vanner CAN Interface User Manual which is available at
