그 이면의 의사결정을 읽어 보세요.
01Sensors feed BMU directly
high-speed ADC sampling is the BMU primary real-time input.
02Protection circuit sits between charger and cells
hardware-level trip is faster than firmware.
03Balancing circuit connects back to cells
passive balancing dissipates excess energy as heat.
Add a thermal management block (coolant pump, heater) fed from BMU for automotive BMS; add a state-of-health estimator for second-life battery systems.
