Technologies described herein are directed to the prioritized delivery of energy to primary and accessory electrical components associated with a vehicle that is at least partially electrically powered, as well as to a power source of the vehicle itself. To operate accessory electrical components in parallel to delivering power to a vehicle battery, the embodiments described herein facilitate understanding dynamic energy available to the accessory electrical components as well as the vehicle battery, and then managing the usage of energy in a prioritized manner to optimize the whole system performance that is aligned with user priorities with regards to energy availability and energy needs.

Method for controlling and regulating a rechargeable battery having energy storage cells, control electronics, a voltage measurement device and a sensor device, wherein the sensor device and the energy storage cells are respectively connected to one another via at least one controllable switching element so that electrical energy can be conducted from the energy storage cells to the sensor device. The method includes: capturing a first voltage value of the first and second energy storage cells of the voltage measurement device, and adjusting the at least one switching element from a deactivation mode to an activation mode if the difference between the voltage value of the first energy storage cell and the voltage value of the second energy storage cell reaches a predetermined threshold value, in order to conduct electrical voltage from the energy storage cell with the higher voltage value to the sensor device.

A battery pack includes a housing having a positive terminal and a negative terminal. Battery cells are located within the housing and are selectively coupled to the positive terminal and coupled to the negative terminal. A battery management system is located within the housing and is configured to operate a first switch within the housing to selectively couple the battery cells and the positive terminal. A bleed circuit is electrically coupled between the positive terminal and the negative terminal. The bleed circuit includes a resistor and a second switch to selectively couple the positive terminal to the negative terminal. The battery management system is configured to open the first switch and close the second switch and measure a voltage drop across the resistor to detect a presence and type of voltage source connected to the positive terminal.

In a battery charging system (100), a charger (110) and a smart battery (160) enhance safety in recharging a cell (180) in the smart battery (160) by a power supply (130) of the charger (110). The smart battery (160) is communicable with the charger (110). If a communication failure occurs, the charger (110) disconnects the power supply (130) from the smart battery (160). The smart battery (160) and the charger (110) share the same symmetric encryption key for encrypting and decrypting message data, allowing one party to determine if the other part is an authentic one. When the smart battery (160) finds that the charger (110) is not authentic, or vice versa, the power supply (130) and the cell (180) are disconnected. When the smart battery (160) finds that a no-charging condition occurs due to abnormality in the cell (180), the smart battery (160) requests the charger (110) to stop charging, and also disconnects the cell (180) from the charger (110) even if the charger (110) fails to stop charging the smart battery (160).

An energy storage apparatus includes: an energy storage device; a substrate in which a through hole penetrating a main surface is formed; a through member that penetrates the through hole; and a lateral member disposed lateral to the substrate and covering a side surface of the substrate. The lateral member includes an opening through which at least one of two portions of the through member, the two portions sandwiching the through hole, is visually recognizable from the outside.

Embodiments of a device and methods to operating the same are described that can provide high level status information about a battery having multiple modular battery packs which may be arranged in different numbers and/or electrical configurations depending on the specific application. In some embodiments, a smart hub is in communication with battery packs within the battery and configured to selectively query low level status information associated with individual battery packs based on a stored pack configuration that can be updated by a user. The device allows more efficient provision of battery information during flexible assembly and connection of the battery packs.

An electrochemical cell capable of energy storage, includes: a housing that encloses an interior space, a composite body arranged in the interior space and formed from at least two electrodes and at least one separator, and an RFID transponder, the memory of which contains data about the cell.

A hybrid plug-in battery and hydrogen fuel engine vehicle with swappable modular hydrogen tanks and integrated with solar power generation system synergistically combines the advantages of electric vehicle, the solar powered electric vehicle, and the hydrogen fuel engine vehicle. This combination of battery electric vehicle and hydrogen fuel engine vehicle mitigates the issues of prolong charging time of battery electric vehicle and prohibitive high cost of fuel cell electric vehicle. This hybrid configuration of vehicle is able to take advantages of the electric vehicle charging station infrastructure and the hydrogen charging station infrastructure simultaneously. The introduction of the water electrolysis system into the new structure of the hybrid vehicle enables onboard hydrogen generation; has the advantage of conventional hybrid vehicle, but without using fossil fuel. The swappable hydrogen tanks comprise sensors and wireless communication electronic terminals to be shared by all vehicles.

Certain aspects relate to a battery pack for electric vertical take-off and landing aircraft. Exemplary battery pack includes a first pouch cell, a second pouch cell, at least a sensor, where the at least a sensor is configured to sense battery pack data and transmit the battery pack data to a data storage system, and a vent configured to vent the ejecta from the first pouch cell. In some embodiments, battery pack may be configured to power at least a propulsor component.

A current of a storage battery is appropriately controlled depending on the situation. In a battery controller, a battery information acquiring unit acquires information on the storage battery. A first allowable current calculating unit calculates a first allowable current of a battery module in accordance with a rated value of a component through which a current flows by charging or discharging of the battery module. A second allowable current calculating unit calculates a second allowable current of the battery module in accordance with an SOC of the battery module on the basis of the information acquired by the battery information acquiring unit. A third allowable current calculating unit calculates a third allowable current of the battery module in accordance with an SOH of the battery module on the basis of the information acquired by the battery information acquiring unit.
