SLA Features
The SLAP2X9 (Sense Line Assembly Plus) is an electronic module intended to monitor battery module cell group voltages and module temperatures from the High Voltage battery bus in addition to activate cell balancing to improve battery cells’ life. All cell voltages and module temperatures are reported directly to the VICM3 on a regular periodic basis via Wireless communication through the BRFM. The SLAP2X9 implements a Cell Monitoring Unit board that uses a Pinnacle IC (ADRF8800), this is an IC that provides wireless communication between the Battery Cell Monitoring chip and the Battery Management System Controller. SLAP2X9 operates in the frequency range 2.405 GHz – 2.480 GHz (ISM band) by using Wireless battery management technology.
Duty Cycle
SLAP2X9 can send 3 packets per 100ms + 3 packets (health reports) every
minute. With a path stability of 80%, this means (30*60+3)/0.8 = 2253.75
transmissions per minute or 37.5625 transmissions per second.
The max TX length is 1.016 ms
37.5625 TX per second with each TX being 1.016 ms = on for 38.1ms every second
= 3.81% of Duty Cycle. The 27% Duty Cycle belongs to the Dual BRFM (FCC ID:
NT8-BRFM/IC: 3043A-BRFM).

measurement shall vary by no more than +/- 2.0dB from the golden sample. Tx
output power shall vary by no more than +/-2.5dB from the golden sample. Radio
frequency reference shall be within ± 20PPM from desired
frequency (2.44GHz, channel 7).

Digital (discrete state) Output
Communication Bus
Note: This section assumes that production software is not mandatory;
the use of specialized software is acceptable.
Note: Software diagnostic timers should be reset to minimum detection values, to facilitate assertion of potential diagnostic flags during the RF exposure time (maximum 2 seconds).
Note: States/faults/issues shall be reported directly over the communication bus (i.e., Class 2, Controller Area Network (CAN), etc.) or indirectly if the communication bus is not available via the cycling of output(s) (e.g., PWM duty cycle change, telltale flash rate change, etc.)
Note: Unless otherwise specified in the EMC Test Plan, in order to ensure a refreshed value, all information related to data monitoring (such as analog input voltages, operating states, etc.) shall be via parameter requests (e.g., Parameter ID (PID)) and not via scheduled, or periodic, broadcast messages. This ensures bi-directional communications during immunity testing.
The following information shall also be included in the case of radio equipment intentionally emitting radio waves:
- Frequency band: 2.405 – 2.480 GHz
- Maximum radio-frequency power is transmitted in the frequency band(s) in which the radio equipment operates. Max output power = 10 dBm (U.S.A. and Canada)
FCC
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
- This device may not cause harmful interference, and
- The device must accept any interference received, including interference that may cause undesired operation.
- Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
RF exposure safety
This device complies with the FCC RF exposure limits and has been evaluated in
compliance with portable exposure conditions. The equipment must be installed
and operated and was evaluated with minimum distance of 5.67 cm of the human
body. This distance or greater is maintained by vehicle design and ensures
compliance by normal use of the vehicle. For a Class B digital device or
peripheral, the instructions furnished the user shall include the following or
similar statement, placed in a prominent location in the text of the manual:
- Hereby, Visteon Corporation, declares that this SLAP2X9 is in compliance with the essential requirements and other relevant provisions of Directive 2014/53/EU.
Note
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more
of the following measures:
- reorient or relocate the receiving antenna.
- increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
ISED CANADA
This device complies with Industry Canada License-exempt RSS standard(s).
