The NovaCarts system is used to control, charge and discharge vehicle traction batteries. The compact device is operated on a three-phase industrial supply network and can be used flexibly due to its construction on rollers. When charging a battery, power is taken from the mains, when discharging, the power withdrawn from the battery is fedback into the mains.
Vehicle traction batteries that gradually discharge slightly due to longer storage periods can be recharged to defined State-of-Charge (SOC) values in a controlled manner with the aid of the charging and discharging device (extension of service life). In order to minimize transport risks, the batteries can also be discharged to a required SOC (e.g. for air freight).
In order to charge or discharge a battery, the battery control unit is supplied with voltage and the necessary CAN messages. This is done with the help of the so-called rest bus simulation, which must match the respective traction battery.
