Conformal coating
A thin polymer film — acrylic, silicone, polyurethane or parylene, tens of micrometres thick — sprayed, dipped or vapour-deposited over a circuit board so that it follows the components. It keeps condensation, dust and electrolyte vapour off BMS electronics at far less mass than potting, but gives no mechanical support.
- Also called
- PCB coating, parylene coating
Example
Data, communication and electronics: an example situation
2500 in a log might mean 25.00 °C, 2.5 V or raw counts. Units and scale must accompany the value.
Read Conformal coating alongside Battery management system in this context. The electronics and software that keep a battery inside its safe window: measuring every cell voltage and many temperatures, estimating SOC and SOH, balancing cells, computing current limits, controlling the contactors and reporting over the vehicle network.
Use in Lemonergy
