Battery charge balancing circuit has positive temperature coefficient resistor as a defined current limiter, via which connection is made between two positive poles of successive batteries

摘要

The circuit has at least one electrical charging source (2,9) at least two batteries (1,8) connected in a parallel circuit with the electrical charging source and a positive temperature coefficient resistor (4) as a defined current limiter, via which the connection is made between two positive poles of successive batteries. An independent claim is also included a crane vehicle with two on-board electrical systems with batteries connected via a current limiter.
