Umladeelektronik

The innovation relates to a Umladeeiektonik according to the preamble of the main claim; An application of the innovation may be, for example, in the automotive industry.

The basic principle of the present invention relates to a system structure consisting of at least two accumulators of any voltage connected in series, which are charged by a common generator. One of the accumulators serves

for feeding the attached consumers, so that there are different loads for the accumulators; as a result, one of the accumulators can thus become empty while the other still has its full charge capacity.

The object of the present innovation is therefore to provide a circuit structure for a possible Veriustfreien transshipment of batteries.

This problem is solved by the means and measures specified in the protection claims; a block diagram also illustrates the circuit-basic structure of the innovation.

This basic structure consists in the two accumulators A connected in series₁ and A₂* which can be recharged via a common generator (G)

and of which an A₁ for supplying the respective consumer V is used. The most important object of an innovation is now the allocation of a low-loss, potential-free charging converter L in conjunction with a voltage control circuit to determine the respective state of charge of the accumulators h. and Ap- According to another combination of features

the charging converter consists of a clocked control unit with low-loss power amplifier and has control inputs for voltage monitoring with a so-called "greater - smaller - equal" evaluation, in logical conjunction with the control of the charging converter L as a function of the respective state of charge of the accumulators A, and A._?, The charging energy for the recharging of the connected to the consumer or consumers V accumulator A, ie from the accumulator A.₂ in which the current and voltage at the charge converter L are controlled in such a way that, after a certain time dependent on the capacity of the accumulators A and A, a charge balance is achieved between them.

If this so-called tie is reached, the charge controller automatically shuts off and only comes back into operation when a renewed charge difference between the two accumulators has arisen.
