Description

The EVHR1211-Y-00B is an evaluation board for lithium-ion batteries, which are typically used in emobility and uninterruptible power supply (UPS) applications. The EVB can also be used as a generalpower supply unit. The device regulates the output voltage to 58.8V if there is not a battery present. Thissolution is based on a PFC + LLC combo controller from a single integrated circuit (the HR1211).Instead of using costly, low-frequency filters, the EVHR1211-Y-00B offers excellent power factor levelswith active power factor correction (PFC). The design shows high power density with low overall cost. Inthe place of diodes, synchronous rectification (SR) reduces the voltage drop, and constant current (CC)and constant voltage (CV) control ensures the battery is charged properly.Lithium-ion batteries generally require a battery management system (BMS) to ensure that the batteryoperates within safe parameters. This charger can interact with a BMS through a relay signal. This helpsprevent high-current spikes in the output connection, which can trigger BMS protections.Electromagnetic compatibility (EMC) tests, harmonic emission tests, and no-load consumption tests wereutilized to ensure that this solution meets industry standards.
