Abstract: Electric powered forklifts or cleaning machine have attracted much attention in the last decade because of their very substantial benefits. The main issue facing the efficiency of Electric forklifts is the charging time needed for the battery pack. To achieve the Ultra-fast charging for the battery. An AC-DC or DC-DC converter is added inside the battery compartment. The converter enables the charger to supply high power and voltage as the converter step-down the voltage to the standard battery voltage. By using this method, the charging time will be reduced without using big or bulky cables.

Abstract: Fast chargers have recently become widespread due to their ability to reduce charging times. Because of the high power needed from the grid, these chargers need a very complicated infrastructure with high rated components like connectors, cables, and breakers which are not commonly found. Installing a used battery with the charger helps reduce power drawn from the grid as the battery supports the charger to supply the needed power to the load. Therefore, the user can enjoy fast charging without the need to invest in changing their infrastructure. The batteries can also supply power during peak periods when electricity prices are high, which will reduce the user peak demand, thereby reducing the electricity bill. The charger can also be upgraded with a converter to integrate solar panels into the system, where the solar panel supplies the power to the batteries as well as the grid.

Abstract: The ongoing electrification revolution, originating in the automotive industry, has now expanded into the marine sector. This transition from internal combustion engines to electric motors necessitates careful adjustments due to the unique characteristics of electric motors, notably their high starting force. In the context of watercraft, where structural modifications are undesirable, this disclosure introduces a drive system fixation unit. This unit effectively redirects the sterndrive force from the stern wall to the sturdy structural base of the watercraft, ensuring a seamless integration of electric propulsion without compromising the vessel's integrity.

Abstract: Disclosed herein are different charging stations, systems, and methods for recharging swappable or non-swappable batteries having differing states of health, impedance, age, etc. Swappable and non-swappable battery packs may be charged in parallel, but the amount of charge current supplied to each parallel battery pack is determined individually by the battery pack itself. Each battery may have its own maximum charge and/or discharge current limits set individually to avoid using a battery pack over its rating, provide voltage equalization, and control energy flow among the plurality of rechargeable battery packs. This also extends the operating lifetime of older battery packs. In a charging mode, a battery charger may set a floating voltage and each battery pack may take its own current to provide voltage equalization. Additionally, a battery pack can boost its own voltage to maintain the required voltage level by a particular load/application.
