Abstract

The battery protection system in accordance with the invention comprises a case; switching means mounted in the case and having a first terminal for electrical connection to a charge source for a battery, and a second terminal for electrical connection to the battery; signal input means attached to the case to receive one or more signals from control means; a control board mounted in the case and connected between the switching means and the signal input means to control the operation of the switching means as a function of the said one or more signals; and a removable coating covering the switching means, the terminals and the control board in the case.

Claims

1. Battery protection system comprising:

a case;

switching means mounted in the case and having a first terminal for electrical connection to a charge source for a battery;

a second terminal for electrical connection to the battery;

signal input means attached to the case to receive one or more signals from a control means;

a control board mounted in the case and connected between the switching means and the signal input means to control the operation of the switching means as a function of the said one or more signals; and

a removable coating covering the switching means, the terminals and the control board in the case.

2. A battery protection system as described in claim 1, wherein the removable coating is a thermofusible adhesive.

3. A battery protection system as described in claim 1, wherein the switching means comprise a relay.

4. A battery protection system as described in claim 3, wherein the relay is a bistable relay having a default position that electrically connects the first terminal and the second terminal.

5. A battery protection system as described in claim 1, wherein the case has an opening adjacent to the switching means.

6. A battery protection system as described in claim 1, wherein, in operation, the switching means comprise a hot portion and a cold portion, said control board being arranged adjacently to the said cold portion, at a distance from said hot portion.

7. A battery protection system as described in claim 6, wherein the control board is connected to the switching means by electrical contacts that are situated at the level of the cold portion.

8. A battery protection system as described in claim 1:

wherein the switching means comprise a relay box; and

wherein the terminals projecting from the relay box, the relay box, the control board, and the said signal input means together form an assembly having a substantially rectangular shape.

9. A battery protection system as described in claim 1, wherein the control board includes board control means able to implement a process for battery management and/or battery diagnostics.
