Safety mechanisms for a rechargeable battery
A safety mechanism of a rechargeable battery for light electric vehicles. The rechargeable battery may include a housing containing a battery management system and at least one battery cell, and a communication system communicatively coupled to the battery management system, to communicate information received from the battery management system to a device external to the rechargeable battery. The rechargeable battery may include a housing formed of a first clamshell member and a second clamshell member. The rechargeable battery may include a first protrusion portion extending from an interior surface of the first clamshell member and a second protrusion portion extending from the interior surface of the second clamshell member toward the first protrusion portion such that the first and second protrusion portions physically contact one another when a force is applied to an external surface of the housing.
1. A rechargeable battery comprising:
a housing including a first clamshell member and a second clamshell member that are mutually engageable and, when engaged, define an interior having a battery management system and a plurality of battery cells contained therein;
a first protrusion portion extending from an interior surface of the first clamshell member toward an interior surface of the second clamshell member;
a second protrusion portion extending from the interior surface of the second clamshell member toward the interior surface of the first clamshell member,
wherein the first and second protrusion portions physically contact one another with a force applied to an external surface of the first clamshell member opposite the first protrusion portion; and
a communication system communicatively coupled to the battery management system,
wherein the communication system wirelessly communicates information received from the battery management system to an external device.
2. The rechargeable battery of claim 1 , further comprising:
one or more rib portions extending along the external surface of the first clamshell member.
3. The rechargeable battery of claim 1 , wherein the first protrusion portion is molded as a unitary part of the first clamshell member.
4. The rechargeable battery of claim 1 , wherein the communication system wirelessly communicates the information while the rechargeable battery is in a charging state.
5. The rechargeable battery of claim 1 , wherein the communication system wirelessly communicates the information to the external device while the battery management system is in an inactive state.
6. The rechargeable battery of claim 1 , wherein the battery management system determines whether the rechargeable battery is coupled to a light electric vehicle.
7. The rechargeable battery of claim 1 , wherein the communication system wirelessly communicates information received from the battery management system to the device external to the rechargeable battery using at least one of a near-field communication (NFC) protocol.
