Page 16: Setup A System
The modules can be connected in “x1” or “z2” direction for Easy Blade. For Easy Block “x3” and or “y3” directions are possible via two module connectors, shown below in black. Place the module connectors inside the recess of two modules (see below picture). - Page 17 The modules can be connected in z1 (Easy Blade) and z3 (Easy Block) directions. You can stack the batteries via the design features on the bottom and on the top of each module. (see below picture).

Page 19: Configuration Of A System
Technical details: Batteries which are not configured will not have a valid Node ID and will also not send any messages on the CAN bus. When configuring the system by pushing the button for at least 5s, the batteries will determine the master of the system dependent on the highest serial number of the batteries. -

10 Charging Charge algorithm is controlled by the battery itself. Either a VARTA-approved charger can be used or also a customized charger which follows the CANopen standard and the VARTA ASB charger specification, which is available on request for custom developments. Charging will not start without CAN communication. - Page 23 Error Description 1 ERROR_NR_OVER_TEMP_LADEN_ZELLEN 2 ERROR_NR_UNDER_TEMP_LADEN_ZELLEN 3 ERROR_NR_OVER_TEMP_LADEN_FET 4 ERROR_NR_OVER_TEMP_ENTLADEN_ZELLEN 5 ERROR_NR_UNDER_TEMP_ENTLADEN_ZELLEN 6 ERROR_NR_OVER_TEMP_ENTLADEN_FET 7 ERROR_NR_OVER_TEMP_CLAMP 8 ERROR_NR_OVER_VOLTAGE 9 ERROR_NR_UNDER_VOLTAGE 10 ERROR_NR_DEEP_LOW_VOLTAGE 11 ERROR_NR_CELL_DISBALANCE 12 ERROR_NR_AKKU_PACK_SPN_MIN_ERROR 13 ERROR_NR_AKKU_PACK_SPN_MAX_ALARM 14 ERROR_NR_AKKU_PACK_FUSED_SPN_DIFF_ERROR 15 ERROR_NR_AKKU_PWR_SPN_DIFF_ERROR 16 ERROR_NR_AKKU_PWR_SPN_MIN_ERROR 17 ERROR_NR_AKKU_PWR_SPN_MAX_ERROR 18 ERROR_NR_AKKU_NETZ_SPN_MIN_ERROR 19 ERROR_NR_AKKU_NETZ_SPN_MAX_ALARM 20 ERROR_NR_AKKU_REKUPERATIOM_SPN_MAX_ALARM 21 ERROR_NR_I_CHARGE_SC 22 ERROR_NR_I_CHARGE_OCC_1...

Page 28: Can-Communication
Charge rate: What are impacts of 0.7C or higher on Cycle life? Easy Blade – cycle life will be significantly reduced and we would not recommend this product for daily fast-charge use case. Use of 1C charge rate for every cycle will reduce cycle life by 75%. -
Page 29: Tpdo/Sdo
Additional signals via a separate plug connection are required for communication. Does Varta provide some software tool to inspect the battery's state? Recommended Standard CANopen SW for Debugging / Read out CAN Objects is CANopen Device Explorer from Emotas (https://www.emotas.de/produkte/canopen-device-explorer) -

Master Remaining Capacity: this is relative to what value? Is it in mAh or some kind of percentage/ratio? The Master Remaining Capacity is in mAh unit. FCC / RC = SOC TPDO9: What are the conditions for the TPDO9 to be transmitted by the master battery? The battery will send the PDO9 as soon it recognizes a heartbeat from Node ID 100dez (charger) and when the charger is configured by the battery via SDO read/write requests. -
Page 31: Mechanical
Higher charge rates on a continuous basis will reduce the cycle life. For the Easy Blade, regular charge rates >0.7C will reduce cycle life significantly. For the Easy Block, the cell technology is not so affected. It should be avoided where possible to store the batteries when empty for an extended period;... -

Does the design feature that allows connection in height also provide a mechanical lock like the module connectors do? No, they don’t lock in the same way, it is more for stability. Do you sell copper bus bars for parallel connection of batteries? No, but this should be possible to organize with our distributors of the ASB range. - Page 33 Contact details The Netherlands Belgium UK & Ireland Elektrostraat 17 Zuiderlaan 14 bus 10 St. Mary’s House, Church Lane NL-7483 PG Haaksbergen B-1731 Zellik Carlton Le Moorland Lincoln LN5 9HS +31 (0)53 573 33 33 +32 (0)2 462 01 00 +44 (0)1522 789 555 F: +31 (0)53 573 33 30 +32 (0)2 462 01 25...
