b.
This international search report has been established taking into account the rectification of an obvious mistake authorized by or notified to this Authority under Rule 91 (Rule 43.6bis(a)).
c.
With regard to any nucleotide and/or amino acid sequence disclosed in the international application, the international search was carried out on the basis of a sequence listing:
2. Certain claims were found unsearchable
3. Unity of invention is lacking
This International Searching Authority found multiple inventions in this international application, as follows:
1. claims: 1-6, 8-14, 16-21
Evenly distributing temperature among parallel chargers
1.1. claims: 1, 2, 5, 6, 8-10, 13, 14, 16-18, 21
Basic details on the realization
1.2. claims: 3, 4, 11, 12, 19, 20
Packaging of the chargers
2. claims: 7, 15
Pre-regulator and thermal protection therefor
1.
As all required additional search fees were timely paid by the applicant, this international search report covers all searchable claims.
2.
As all searchable claims could be searched without effort justifying additional fees, this Authority did not invite payment of additional fees.
3.
As only some of the required additional search fees were timely paid by the applicant, this international search report covers only those claims for which fees were paid, specifically claims Nos.:
4.
No required additional search fees were timely paid by the applicant. Consequently, this international search report is restricted to the invention first mentioned in the claims; it is covered by claims Nos.: 1-6, 8-14, 16-21
Remark on Protest
The additional search fees were accompanied by the applicant’s protest and, where applicable, the payment of a protest fee.
The additional search fees were accompanied by the applicant’s protest but the applicable protest fee was not paid within the time limit specified in the invitation.

5. Abstract
The text is approved as submitted by the applicant.
The text has been established, according to Rule 38.2, by this Authority as it appears in Box No. IV. The applicant may, within one month from the date of mailing of this international search report, submit comments to this Authority.

A method for supplying power to a battery determines (1200) a first thermal budget for a first charging regulator. The method also determines (1202) a second thermal budget for a second charging regulator. The first charging regulator and the second charging regulator are coupled to the battery. The method further includes dynamically increasing (1204) a first charging regulator power output and substantially simultaneously decreasing a second charging regulator power output based on the first thermal budget and the second thermal budget.


6. Drawings
a.
The figure of the drawings to be published with the abstract is Figure No.     12    
as suggested by the applicant.
as selected by this Authority, because the applicant failed to suggest a figure.
as selected by this Authority, because this figure better characterizes the invention.
b.
none of the figures is to be published with the abstract.
