Page 2: Important Notice
NXP sales and technical support services. 2 Introduction The RD-BESS1500BUN is an electrical transport protocol link (ETPL) based battery energy storage system (BESS) reference design bundle for 1500 V applications. This bundle has been designed for evaluation and development purposes. The RD-BESS1500BUN is composed of a hardware kit and several software packages. -
Page 3: Kit Content
• Links to the software and safety kits Note: A BESS startup interface is available on the RD-BESS1500BUN website to visualize cell voltage measurements at first startup. This interface is a GUI matching with a binary file that is preflashed on the BMU. -
Page 4: Getting To Know The Hardware
UM12117 NXP Semiconductors RD-BESS1500BUN user manual 4 Getting to know the hardware 4.1 Battery management unit The BMU is the control part of the BESS. The BMU processes the data, decides, and commands the system. The RD-BESSK358BMU is the BESS reference design BMU for 1500 V applications. This BMU kit includes a power supply and five cables to interface with other parts of the BESS. -
