Patent ID: 11933860
Assignee: nan
Field: Measurement (Instruments)
Classification: CPC G  H  Y | IPC G  H

Claim 0:
1. A circuit assembly for forming and testing batteries comprising:
a battery testing system (BTS) having channels for testing multiple batteries simultaneously;
a parallel test management device (PTMD) for each battery, wherein each PTMD connects to its respective battery serially to form a PTMD-battery combination, the PTMD comprising:
a main relay or switch for connecting to a battery;
a current transducer or shunt connected in series with the main relay or switch, wherein each of the current transducer and the shunt is configured to measure current through the respective battery; and
an auxiliary relay connected in series with a current limiting resistor, wherein the auxiliary relay and the current limiting resistor are parallel to the main relay; and

circuits for connecting PTMD-battery combinations in parallel to form parallel PTMD-battery groups and for connecting the parallel PTMD-battery groups to a BTS channel,
wherein the BTS channel is configured to provide programmed current, voltage or power, wherein the BTS channel is configured to pass current through each battery in a parallel PTMD-battery group, wherein current is distributed to each battery in a balanced manner, and
wherein the BTS channel is configured to provide programmed current, voltage or power to multiple batteries simultaneously, thereby forming or testing multiple batteries with one BTS channel.
