Loadwasher

connections to SC

• depending on the PCA assembly, it is possible to use either one, or both the connections to the SC.
• if both connections are made, no ECOs are needed to the SC, and power for the SC side of the PCA is provided from the SC without local support circuitry.

battery dataport

• in this case, no (significant) mods are required to the SC - the load-washer signal is read via the batt-temp signal
• assuming the battery measurement ECO has been made to the SC, this connection can also provide power to the SC side of the PCA
• disadvantage - several more devices need to be populated on the SC side of the PCA.

linear spring connection

• parts needs to be removed and a jumper wire added
• advantage is that the SC 3.0V ref powers the SC side of the PCA.
