Abstract: The wireless management system for energy storage systems includes a plurality of smart cells arranged into a two-dimensional array and a plurality of distributed management units. The smart cells and management units communicate with each other wirelessly via capacitive coupling (not radio). The communication links have extremely short range (typically under 3 mm), are relatively directional, and are electronically-steerable in the plane of the array. The smart cells may also include at least one power resistor and switch for passive cell balancing. The circuitry in the smart cells is typically incorporated into a flexible sheet that wraps around the energy storage device like a label. This system is extremely reliable because it is massively redundant, fault tolerant, and eliminates the wires used in conventional monitoring systems.

Abstract: A smart junction box for a photovoltaic solar power module, and related method of operation. The junction box includes a plurality of active bypass circuits for protecting the solar cells from reverse bias, a novel power supply circuit in several embodiments that can operate with input voltages of either positive or negative polarity, a capacitor for storing and supplying energy, and a master control circuit. The master control circuit is able to enable/disable the power supply, force the bypass switches to open, and modulate the on-resistance of the bypass switches. The master control circuit performs these functions in a coordinated way to maintain the voltage across the capacitor within predetermined limits, thereby ensuring the internal circuitry is powered under all operating conditions including: full sunlight, partial shading, full shading, and safe mode for reducing the risk of electrical shock to firefighters.

Abstract: The invention comprises: a smart junction box with a safe mode for photovoltaic solar power modules; and the related method of operation. Power MOSFETs are used as active bypass diodes during the normal operation of the smart junction box, but in safe mode the power MOSFETs are turned on continuously, thereby reducing the output voltage to a safe level of approximately 200 mV. A Non Volatile Memory (NVM) keeps the module in the safe mode after power from the PV cells is interrupted by momentary shading or night. The smart junction box includes transmitter and receiver circuits for wirelessly communicating with other smart junction boxes. The smart junction box enters safe mode in response to receiving a shut-down signal, and exits safe mode in response to receiving a restart signal. The smart junction box acts as a signal repeater, thereby ensuring that the shut-down and restart signals propagate to all junction boxes in the solar array.
