Classification: CPC G  H  Y | IPC G  H

Claim 45:
46. A circuit assembly for forming and testing a plurality of batteries, comprising:
a current transducer for connecting to a battery in series;
a voltage equalizer connected in parallel to the current transducer, wherein the voltage equalizer is connected to the current transducer through a battery;
a circuit board or an alternative means for receiving and connecting to the plurality of batteries and for receiving electrical components and for providing circuits among the electrical components and between the electrical components and the batteries;
a parallel test management device (PTMD) according to claim 43 for each battery, wherein each PTMD connects to its respective battery serially to form a PTMD-battery combination, wherein the current transducer or shunt of the PTMD is configured for measuring equalization current and all other current through a battery for precise measurement of and calculation of current and charge/discharge capacity through the battery;
circuits for connecting PTMD-battery combinations in parallel to form a parallel PTMD-battery group and for connecting the parallel PTMD-battery group to a BTS channel or to a regulated power source, wherein the BTS channel or the regulated power source provides programmed current, voltage or power, and wherein current is distributed to each battery in a balanced manner;
an equalizer power supply connected to the voltage equalizer,
a power supply port for receiving an electrical current from an outside source,
wherein the voltage equalizer is connected to the parallel PTMD-battery group; and
wherein the BTS channel or the regulator and the voltage equalizer power supply are connected to the power supply port,
wherein a BTS channel or the regulator is connected to each PTMD, wherein the BTS channel or the regulator provides a current and voltage source for charging and discharging the batteries, and
wherein the batteries are formed and tested by running current from the BTS channel or the regulator and from the equalizer through the plurality of batteries simultaneously.
