Title: How to separate and combine high capacity batteries
Inventor: AN HEUI TAY
IPC: B60R16/04
Filed: 2021-01-22
Abstract: High-capacity batteries, which are composed of multiple packs, are robustly connected for high output. In a case in which wiring connection is disconnected for movement, there is a risk of accidents due to short circuits, and in case of incorrect reconnection, a fire may occur. The wiring is easily disconnected using connectors having determined polarities, and prevents miswiring. To prevent overcurrent caused by voltage differences, external voltage of each pack is compared with internal voltage, and if the voltage difference is within a set range, wiring connection is made. The battery pack (1) is composed of a plurality of battery cells. A connector (2) has a determined direction for connection of the same polarities. A voltage comparator (3) compares the external voltage and the internal voltage. A coupler (4) connects an internal power supply and an external load. A controller (5) operates the connector (4) to connect the internal power supply and the external load when the difference between the internal voltage and the external voltage is within a predetermined voltage range.
