POWER-LINE COMMUNICATION (PLC)

PLC Tuning

Power-Line Communication (PLC) is used during charging of electric vehicles around the world and is a must-have in today’s electric vehicle (EV) market. PLC allows the charging station (aka electric vehicle supply equipment or EVSE) and the EV to negotiate charging sessions, allowing various charging profiles and potentially to negotiate payment. Pi Innovo’s M560 and M580 modules have PLC capability built in. Power-Line Communication (PLC) as depicted in ISO 15118-3 and DIN 70121 specifies power spectral density (PSD) limits of... View More

DV BATTERY MANAGEMENT UNIT (BMU) EMISSIONS ISSUE

DV BMU Emissions Test Issues

During development of our Battery Management Unit (BMU) we performed DV testing and found an issue in the radiated emissions test. Our schedule to meet the customers deadlines was tight so we did not perform pre-DV emissions scans which would have caught this failure earlier. We had to find a solution quickly to keep the BMU project on schedule so we needed to narrow down the root cause of the emissions failure, find a workable solution... View More
