System Features and Overview
CBC-EVAL-10 is a demonstration kit that provides
designers a platform to easily develop Energy
Harvesting (EH) solutions using the EnerChip
CBC3150
harvesting mode. The kit combines a small solar
panel, power management circuit, energy storage,
regulated output voltage, and input/output pins for
connection to commercially available microcontroller
(MCU) and radio boards. A 16-pin CBC51100 module
is included, providing the EH functions, battery
management, and 100µAh solid state rechargeable
energy storage. CBC-EVAL-10 is a practical, low
cost realization of an EH-based power system that
can provide many years of service without need of
battery maintenance.
CBC-EVAL-10 has the following elements:
The photovoltaic (PV) panel included in the CBC-
EVAL-10 converts ambient light energy into electrical
energy, which is fed into the CBC3150 device
residing on the CBC51100 module. The CBC3150
performs several important functions:
DS-72-20 Rev A
Energy harvesting circuitry that matches the
impedance of photovoltaic cells to ensure
maximum power transfer to system load and on-
board energy storage devices
Solid state energy storage with thousands of
charge-discharge cycles available
Integrated battery management that controls
battery charging and discharge cutoff, ensuring
maximum service life of on-board storage cells
Provision for additional energy storage (primary
or rechargeable batteries) with switchover
control circuit to meet application requirements
Regulated output voltage with user-configurable
voltage settings
Input/output headers for connection to system
components such as radios and microcontrollers
Decouples the load impedance from the PV cell
impedance to ensure maximum power conversion
efficiency from the PV transducer to the energy
storage and system load.

... Once the peak power point of the PV cell has been determined, the CBC3150 operating point can be adjusted to match the PV cell. This is done by adding a resistor divider R2 and R3 to the CBC-EVAL-10 module. As shipped, those resistors are not populated. Cut the solder trace in the R2 location prior to adding the resistor. ...

... The CHARGE/ line on the CBC-EVAL-10 has a 1.0MΩ pull-up resistor with a very slow rise time. Use an internal microcontroller pull-down resistor to force the CHARGE/ line low all of the time and then disable the pull-down resistor to check the state of the line. This will keep the CHARGE/ line from biasing the input at mid level for long periods of time, which could case large parasitic currents to flow ...

... This depends on many factors, including load power consumption, EnerChip state-of-charge, operating temperature, etc. The EnerChips on the CBC51100 module provide 100µAh of discharge capacity when fully charged. Q: How long will the CBC-EVAL-10 module last if I use it every day and input power is available most of the time? A: The CBC-EVAL-10 module should last at least 10 years. ...
