Abstract:
A method and system for enhanced battery control improves the performance of a hybrid electric vehicle (HEV). The HEV includes an internal combustion engine, at least one motor operable as a generator and a battery. A hybrid control module determines various discharge and recharge allowances limiting operation of the battery with different operating conditions of the hybrid electric vehicle. It also determines various periods of time limiting operation of the battery with different operating conditions of the hybrid electric vehicle. The allowances and periods of time may be used as limits that are imposed on commands for the motor.
Abstract:
A battery starter pack comprises a housing having a base 2, a top 3, a rear 4, a front panel 5 and a pair of sides 6, 7. The sides 6, 7 extend forwardly and rearedly proud of the rear 4 and front 5 to define an area which protects various switches 25, 26, 27, 28 if the pack is toppled over. The starter pack incorporates a switching system to avoid accidental switching of the unit into a 24 volt setting while it is connected to equipment which is not designed to take a 24 volt charging supply.
Abstract:
In a machine for supplying electricity it is known to operate occasionally. In this invention we have several parts that are all connected to each other. The components that can be interchangeable would be the altinator or generator, both of which will accomplish the same results. The batteries, electric motor, male plug and belt, Inverter with (2) or more female recepticals and an altinator are all in the equasion.
Abstract:
The subject invention is about a portable battery jump starting device for stranded vehicle due to weaken starting battery. It is equipped with a pair of power cable connected to crocodile clips. The internal circuit of the subject invention is capable of detecting polarity at the point of connection to the external battery and is capable of compensating a wrong polarity connection. The subject invention offers automatic power on/off and a will guarantee a correction connection at any circumstance. Therefore it eliminates the risk of battery explosion due to human error.
Abstract:
To provide a method of controlling charge and discharge of a secondary battery for automatic guided vehicle that can decide the timing of refresh charge and discharge accurately and minimize the frequency of refresh charge and discharge. The method of controlling charge and discharge of a secondary battery for automatic guided vehicle comprises a first discharge step of making the secondary battery drive an automatic guided vehicle and discharge electricity with a predetermined amount; a voltage measurement step of measuring a discharge end voltage of the secondary battery at the completion of the first discharge step; and a charge step of performing a first charge step of charging the secondary battery incompletely at a first charging current value when the discharge end voltage is higher than a preset minimum voltage, and performing a second charge step of discharging the secondary battery fully and then charging the secondary battery fully at a second charging current value smaller than the first charging current value when the discharge end voltage equals the preset minimum voltage or less.
Abstract:
A portable jump starter/charger combination includes a housing and a jump starter battery enclosed within the housing for providing a first DC output. A battery charger is also enclosed within the housing and provides a second DC output. A function selector switch has a first input coupled to the first DC output of the jump starter battery, a second input coupled to the second DC output of the charger and an output coupled to battery cables. The function selector switch is operative to selectively connect one of the first and second inputs to the output of the function selector for either jump starting a vehicle with a dead battery or charging the dead battery through the pair of battery cables.
Abstract:
An onboard power supply system includes a power generator, a main battery, a sub-battery, and a control device. The main battery is charged by the power generator. The control device controls charge and discharge of the sub-battery according to at least one of a state of charge of the main battery and a state of power generation of the power generator.
Abstract:
A method and system for modeling or simulating an application environment so as to evaluate the effect of a selected battery and charger in the application environment. Sensors are used to gather data regarding the energy consumption needs of the application environment over time. Based on the energy needs and/or user-specified application environment parameters, such as a charge schedule, a battery size and type, and a charge return model, an energy transfer profile for the application environment is generated and outputted. The energy transfer profile provides an indication of the state of charge of the battery over time based upon the simulated discharging and charging of the battery in the application environment. The generation of the energy transfer profile takes into account the charging schedule and the incremental change in battery parameters over time.
Abstract:
A drive system for a battery-powered vehicle comprising an AC or DC motor comprises a rechargeable battery, a voltage boost circuit for enabling the motor to be provided with power at a voltage greater than that of the battery and for enabling the speed of the motor to be controlled, said boost circuit comprising contactors simultaneously movable to lie either at a first position when the battery is discharging to the motor, or at a second position when the battery is being recharged.
Abstract:
The charging system for a vehicle includes: a motor generator which operates as a generator to generate an alternating current when the motor generator is driven by an internal combustion engine, and operates as a motor when an alternating current is supplied thereto; a switching circuit for converting the alternating current generated by the motor generator into a direct current; a first accumulator accumulating therein the direct current converted by the switching circuit; a second accumulator accumulating therein the direct current converted by the switching circuit and having a smaller accumulation voltage than that of the first accumulator; a first opening/closing unit interposed between the first accumulator and the switching circuit; a second opening/closing unit interposed between the second accumulator and the switching circuit; and, a control unit for controlling the opening and closing of the first and second opening/closing units.
