SYSTEM FOR MONITORING OVER VOLTAGE PROTECTION OF BATTERY PACK AND METHOD THEREOF
First Claim
1. An over voltage protection (OVP) monitoring system, comprising:
- a battery pack connected to an external system, the battery pack including a battery;
a first memory to store a voltage value of the battery;
a second memory comprising a first sub-memory and a second sub-memory to store numbers of OVP operations of the battery;
a controller to store the voltage value of the battery in the first memory upon an occurrence of an OVP operation and to increment a number of OVP operations stored in either the first sub-memory or the second sub-memory according to the voltage value of the battery stored in the first memory; and
a signal generator to generate either a first alarm signal indicating a need to check the external system or a second alarm signal indicating a need to check the battery pack according to numbers of OVP operations stored in at least one of the first sub-memory and the second sub-memory of the second memory.

10. A method of monitoring over voltage protection (OVP) of a battery pack, comprising:
-
storing in a first memory a battery voltage value measured upon an occurrence of an OVP (Over Voltage Protection) operation in a battery of the battery pack; incrementing either a number of OVP operations stored in a first sub-memory of a second memory or a number of OVP operations stored in a second sub-memory of a second memory according to the battery voltage value stored in the first memory; and generating either a first alarm signal indicating a need to check an external system connected to the battery pack or a second alarm signal indicating a need to check the battery pack according to a number of OVP operations stored in at least one of the first sub-memory and the second sub-memory of the second memory. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
