A portable jump-starting device includes an internal multi-cell lithium battery pack, a power conversion circuit, and a battery charge and discharge control circuit. The control circuit includes a battery management integrated circuit that monitors cell voltages, current, and temperature, and independently controls transistors arranged in separate charge and discharge current paths. A charge transistor and diode selectively couple a regulated charging source to the battery pack, and a discharge transistor and diode selectively couple the battery pack to external terminal connectors. The battery management integrated circuit disables charging or discharging in response to over-voltage, under-voltage, over-current, or over-temperature conditions. In certain embodiments, a relay is connected in parallel with a discharge diode to provide a low-resistance path during high-current jump-starting operations.

Interconnect device for detecting whether a vehicle on-board diagnostics (OBD) data port includes circuitry which prevents back feeding of power through the OBD data port
An interconnect device is disclosed for detecting whether an vehicle on-board diagnostics (OBD) data port includes a blocking diode or equivalent, that prevents back feeding of power through the OBD data port. If a diode is detected, the interconnect device alerts the user that the power cannot be back fed through the OBD II port connector. In such a condition, an alternate means is used to preserve the data mentioned above. Specifically, an alternative power supply can be connected directly to the battery cables that will be disconnected from the battery, for example, by way of battery clamps. In this way the alternative power supply is used to preserve the data until a new battery is reconnected to the vehicle battery cables. If a diode is not detected by the interconnect device, the interconnect device displays this fact to the user. The interconnect device includes circuitry for detecting and displaying whether a diode is connected in series with a power pin of the OBD II port connector. In addition, the interconnect device includes an OBD II port connector on one end connected by way of a cable to a connector, such as a cigarette lighter connector or hardwired directly to an alternate power supply.

Interconnect device for detecting whether a vehicle on-board diagnostics (OBD) data port includes circuitry which prevents back feeding of power through the OBD data port
An interconnect device is disclosed for detecting whether an vehicle on-board diagnostics (OBD) data port includes a blocking diode or equivalent. that prevents back feeding of power through the OBD data port. If a diode is detected, the interconnect device alerts the user that the power cannot be back fed through the OBD II port connector. In such a condition, an alternate means is used to preserve the data mentioned above. Specifically, an alternative power supply can be connected directly to the battery cables that will be disconnected from the battery, for example, by way of battery clamps. In this way the alternative power supply is used to preserve the data until a new battery is reconnected to the vehicle battery cables. If a diode is not detected by the interconnect device, the interconnect device displays this fact to the user. The interconnect device includes circuitry for detecting and displaying whether a diode is connected in series with a power pin of the OBD II port connector. In addition, the interconnect device includes an OBD II port connector on one end connected by way of a cable to a connector, such as a cigarette lighter connector or hardwired directly to an alternate power supply.

A switched mode converter is disclosed that includes mode logic for switching between voltage mode and current mode. The converter includes sensing circuitry for sensing current on the primary side, load current on the secondary side, and converter output voltage. When load current is less than a predetermined value, the converter operates in voltage mode wherein output voltage of the voltage mode controller is used to control the duty cycle of a PWM controller. When load current is greater than a predetermined value, the converter operates in current mode wherein primary current is used to control the PWM controller. Thus during a light load when the converter is voltage controlled there is no need for a minimum load to stabilize the control loop. In current-mode the control loop will have faster transient response and avoid flux imbalance. Thereby providing advantages of both voltage and current controlled switched mode converters.

Thermal runaway protection system for a battery charger
A protection system and method for a battery charger is disclosed for detecting a thermal runaway condition in a battery during charging in order to protect the battery when such a thermal runaway condition has been detected. The protection system in accordance with the present invention does not require external temperature sensors nor does it rely on actions by the technician or user. Briefly, the protection system includes one or more electrical sensors normally provided with conventional battery chargers for sensing one or more electrical parameters during charging and providing an indication of a possible thermal runaway condition based upon the trend of the electrical charging parameters. In general, the protection system monitors the charging characteristics of a battery for a complete or partial charging cycle. If the charging characteristics deviate from a normal or otherwise indicate an anomaly, as determined by software, the system assumes there may be a thermal runaway condition and executes a protection measure, such as terminating charging of the battery. Even though the anomaly may not be the result of a thermal runaway condition, the protection system in accordance with the present invention treats the anomaly as an indication of a thermal runaway condition even though some other problem is the reason for the anomaly. For example, when the anomaly is the result of a bad cell, battery charging is terminated to prevent a thermal runaway condition and not because a thermal runaway condition is detected.
