摘要:
A method of testing a battery is provided the method may include: (a) applying a heavy load to the battery, (b) measuring the voltage V1 between the positive and negative terminals of the battery after a first time period under which the battery is subjected to the heavy load; (c) removing the heavy load, (d) waiting for a second length of time, (e) reading the voltage across the positive and negative terminals after the second length of time V2, (f) performing a cold cranking amps CCA test if the CCA test indicates a CCA value above a first threshold, then consider V2, if V2 is below the second threshold than skip to step g but if V2 is above a second threshold than determine if the V2 is above a third threshold, if V2 is above a third threshold than determine that the battery is good and skip steps g-h; but if V2 is below the third threshold then if a battery charge flag has been set, determine that the battery is bad and skip steps g and h, if the battery charge flag has not been set, determine that the battery is good but needs additional charging and skip steps g-h, if the CCA test indicates a CCA valve below the first threshold then move to step g, (g) determine if the battery charge flag has been set, if the battery charge flag has been set, then determine that the battery is bad, if the battery charge flag has not been set then move to step h; and (h) applying a charging current to the battery if the charging current is less than a fourth threshold amount then stop charging the battery and return to step a, if the charging current is greater than the fourth threshold amount, then charge the battery for a third length of time then stop charging the battery and return to step a.
摘要:
A single battery connection device that allows for connection both to a battery post and to a battery side terminal. Regardless of whether the device is connected to the battery post or side terminal, the device may be used as part of a four-point Kelvin connection to the battery. Also, a method of connecting to either to a battery post or to a battery side terminal using a single device.

An apparatus and method are provided that allow a scan tool to communicate with a data link connector in a vehicle. A cable that can automatically multiplex its connections in order to make the appropriate connections between the scan tool and a data link connector based on a communication protocol of the vehicle under test. This allows the scan tool to communicate with the data link connector regardless of the pins being used by the communication protocol of the vehicle.
摘要:
A tire pressure monitor system tool stores information regarding a plurality of tire pressure monitor systems installed on vehicles. The tool receives information regarding a particular vehicle. Based on this information, the tool may determine a particular tire pressure monitor system installed on a vehicle. Based on the tire pressure monitor system installed on the vehicle, the tool may determine one or more procedures that may be used with that tire pressure monitor system. The tool may then instruct a user how to perform certain procedures by presenting one or more displays to the user on a display of the tool. The tool may also provide feedback to the user regarding a status of an initiation or other procedure, and reference a vehicle user manual. The tool may interface with an electronic control unit of a vehicle. The tool may also simulate a tire pressure sensor.

摘要:
An apparatus for testing an alternator has a base, a motor mounted to the base and a pulley extending from the motor. A belt is connected to the motor pulley and the alternator. A mount mounts the alternator to the base, and a pivoting idler arm pivotally is mounted with respect to the base and has an idler pulley that engages the belt to apply tension to the belt.
摘要:
A method and apparatus that allows a battery charger/tester to transmit and receive information from a remote location. Information, such as the result of the charge and testing of the battery, can be relayed via a wire or wirelessly to a remote device, such as a server for storage. Additionally, information such as firmware updates can be relayed to the battery charger/tester for upload.
摘要:
An apparatus for a circuit which allows a user to connect various adaptors to a common interface to provide a device with power and data signals. The circuit may provide a device, in which the circuit is incorporated, with the ability to discern whether a connected adaptor is providing power or data at any given time. If the adaptor is providing power at a particular moment, then the power/data circuit can identify that power is being provided and signal the device to accept power. When the adaptor is providing data at a particular moment, then the circuit can identify that power is being provided and signal the device to accept power. The circuit may include a power/data input, a vehicle connector, an internal power source connector, a reference voltage source, a comparator, and sensor.
