Abstract

The disclosed embodiments a battery storage of self-management system provides unlimited parallel battery-powered. For example use in robot engine power batteries bank, solar photovoltaic batteries storage system and any device need storage energy system.

Description

A battery self-management system can provide unrestricted battery pack power supply for parallel application to robots Engine battery and solar photovoltaic battery pack

The disclosed embodiments are directed to a battery pack for any form of energy storage electronic device. More specifically, the disclosed embodiments relate to a battery pack for any form of energy storage electronic device, in which the voltage of a newly added group of parallel battery packs is different from the voltage of other battery packs, resulting in a low voltage battery pack. A battery pack that burns or has a high voltage is a prevention technique that reduces battery life due to excessive discharge.

A battery pack for an energy storage electronic device (such as an electric vehicle (BEV) / an electric motorcycle/electric bicycle battery pack/robot/solar energy storage battery pack, etc.) The charge in such a battery pack is usually managed by a circuit. Protection Circuit Module (PCM) and/or Battery Management Unit (BMU).

In particular, such battery packs are typically manufactured using the same production batch and thus share substantially the same battery cells, such as capacity, self-discharge rate, charge retention characteristics, and/or discharge profile characteristics. Therefore, when one or/and several battery packs are installed, the voltage and capacity have been balanced. In this case, another battery pack needs to be connected in parallel to increase the total capacity. However, the new battery packs are manufactured because they are not manufactured in the same production batch and have no common such as capacity, self-discharge rate, and electricity. A battery cell that is substantially different in characteristics of the charge retention feature and/or the discharge curve. When a new battery pack is added in parallel, the voltage is not the same as other battery packs. The high-voltage battery pack will discharge to the low-voltage battery pack, and the low-voltage battery pack will accept the high-voltage battery pack to charge it. If the current is too large, if there is no PCM or BMU protection, the newly added battery will burn out or affect the life of the battery pack, and the electronic circuit may be damaged.

Therefore, it is conventional to connect two or more battery packs in parallel to adjust the voltage, capacity, self-discharge rate, charge retention characteristics and/or discharge curve characteristics of the battery cells to be the same and then parallel.

Thus, the self-managing battery system technology of the embodiments disclosed herein can provide unlimited battery packs in parallel anytime and anywhere to increase the use of power supply capacity.

The disclosed embodiments provide a self-management technology for battery packs in an electronic device that can provide an unrestricted battery pack in parallel anytime, anywhere to increase the use of power supply capacity.

In some embodiments, when the external voltage of the battery pack is higher than the total voltage of the internal battery, the self-management system is automatically activated, and the internal charging circuit increases the charge to the battery pack until the same as the external voltage, and then the charge and discharge switch is turned on. Connect to an external power source.

In some embodiments, when the external voltage of the battery pack is lower than the internal battery total voltage, the self-management system is automatically activated, and the AFE battery balancer removes the charge from the battery pack until the same as the external voltage. The charge and discharge switch is turned on to connect to an external power source.

In some embodiments, when any battery voltage inside the battery pack is lower than UVP (Under Voltage Protect) and the external voltage of the battery pack is higher than the internal battery total voltage, the self-management system is automatically activated, and the battery pack is first Turn on the precharge switch to increase the charge of each string of batteries until the same as the external voltage, then turn off the precharge switch, and then open the charge and discharge switch to connect with the external power supply.

In some embodiments, when any battery voltage inside the battery pack is higher than OVP (Over Voltage Protect) and the external voltage of the battery pack is higher than the total voltage of the internal battery, the self-management system is automatically activated, and the AFE battery is balanced. The battery removes the charge from the battery pack until the voltages of the strings are the same, and the internal charging circuit begins to increase the battery pack charge until it is the same as the external voltage, then turns off the internal charging circuit, and the charge and discharge switch opens to connect with the external power source.

In some embodiments, when the external voltage of the battery pack is lower than the UVP (Under Voltage Protect) and the total voltage of the internal battery is added, the self-management system is automatically activated, and the AFE battery balancer removes the charge from the battery pack. Until the same as the external voltage, the charge and discharge switch does not open and is not connected to the external power supply, and the alarm signal is sent through the RF wireless communication and/or wired communication and the warning light is displayed.

In some embodiments, the external voltage of the battery pack is slightly higher than the OVP (Over Voltage Protect) and the internal battery total voltage, the self-management system is automatically activated, the charge and discharge switch is not opened, and the external power supply is not connected, and the RF is transmitted. Wireless communication and/or wired communication sends an alarm signal and displays an alarm light.
