A system for suppressing inrush currents is described. The system may include a positive temperature coefficient (NTC) thermistor and a positive temperature coefficient (PTC) thermistor arranged in series between a power source and a battery system to be charged. At a low temperature, while the PTC thermistor provides only minimal resistance to minimize an inrush current, the NTC thermistor provides increased resistance. As the temperature increases, the resistance provided by the PTC thermistor increases as the resistance from the NTC thermistor decreases. The system may be used in conjunction with a battery charging system has at least one current pathway from the power source to the battery system.

A magnetic brake mitigation module is described. During a catastrophic failure of a power supply, magnetic brakes are designed to quickly bring an electric vehicle to a stop. In some electric vehicles with minimal safety systems (e.g., seatbelts or doors), the abrupt stop can be unsafe. The magnetic brake mitigation module determines when a catastrophic failure has occurred and supplies, for a short period, stored power to the magnetic brakes to prevent a maximum braking force from being applied to the wheels.

The discharging of the battery cells is controlled in an efficient manner while preserving the expected life of the Li-ion battery cells. Each battery pack internally supports a battery management system and may have identical components, thus supporting an architecture that easily scales to higher power/energy. Battery packs may be added or removed without intervention with a user, where one of battery packs serves as a master battery pack and the remaining battery packs serve as slave battery packs. When the master battery pack is removed, one of the slave battery packs becomes the master battery pack. Charging and discharging of the battery cells is coordinated by the master battery pack with the slave battery packs over a communication channel such as a controller area network (CAN) bus.

A system for suppressing inrush currents is described. The system may include a negative temperature coefficient (NTC) thermistor and a positive temperature coefficient (PTC) thermistor arranged in series between a power source and a battery system to be charged. At a low temperature, while the PTC thermistor provides only minimal resistance to minimize an inrush current, the NTC thermistor provides increased resistance. As the temperature increases, the resistance provided by the PTC thermistor increases as the resistance from the NTC thermistor decreases. The system may be used in conjunction with a battery charging system has at least one current pathway from the power source to the battery system.

A mode may change how the battery pack discharges power by, for example, altering whether terminals are enabled or disabled. A mode may change how the battery pack's hardware operates by, for example, disabling or enabling portions of the battery pack's hardware. A mode may change what battery-related services are provided by the battery pack and available to an end user by, for example, enabling or disabling the sending of battery status information from the battery pack.

Abrégé

The invention relates to a power management system for supplying backup DC power to peak and/or high current demand battery applications, such as motor starting or an uninterruptible power supply (UPS) used to power a critical load, such as, a data bus or other critical load, after an event, such as loss of primary AC or DC input, during relatively cold ambient temperatures. Two or more heaters can be provided; for example, a low power heater and a high-power heater. In a maintenance mode, the low power heater is used to maintain batteries at a predetermined temperature. In this mode, a battery charger is used to power the low power heater. In a boost mode, after the primary AC or DC input is restored, and battery temperature is too low to back up the critical load, the battery charger supplies power to one or both of the heaters. Since capacity of the battery charger is normally insufficient to heat the batteries to an acceptable operating temperature in a relatively short period of time, a portion of residual power from the batteries is used to boost power to the heaters in order to speed up the time to get each battery of said batteries to its rated operating temperature.

A rapid charging circuit for a lithium ion battery. The battery charger in accordance with the present invention compensates for the voltage drops across the various resistance elements in the battery circuit by setting the charging voltage to a level to compensate for the initial resistance of the series resistances in the circuit and an additional resistance selected to take into account the anticipated increase in resistance of the various circuit elements over time. The battery charger in accordance with the present invention periodically monitors the open-circuit voltage of the battery cell and reduces the charging voltage to when the battery cell voltage reaches the optimal value. Thus, during a constant current charging mode, the battery cell is driven at a relatively optimal charging current to reduce the charging time. As such, the system is able to optimize the charging current supplied to a battery cell during a constant current mode of operation while compensating for circuit elements whose resistance may vary over time due to temperature or other factors, such as corrosion, while at the same time avoiding exceeding the maximum recommended voltage for the battery cell.

A multiple cell battery charger configured with a parallel topography is disclosed. In accordance with an important aspect of the invention, the multiple cell battery charger requires fewer active components than known battery chargers while at the same time protecting multiple battery cells from overcharge and discharge. The multiple cell battery charger in accordance with the present invention is a constant voltage battery charger that includes a regulator for providing a regulated source of direct current (DC) voltage to the battery cells to be charged. In accordance with the present invention, each battery cell is connected in series with a switching device, such as a field effect transistor (FET) and optionally a current sensing device. In a charging mode, the serially connected FET conducts, thus enabling the battery cell to be charged. The battery voltage is sensed by a microprocessor. When the microprocessor senses that the battery cell is fully charged, the FET is turned off, thus disconnecting the battery cell from the circuit. Since the battery cell is disconnected from the circuit, no additional active devices are required to protect the battery cell from discharge. As such, a single active device per cell, such as the FET, provides multiple functions without requiring additional devices. Accordingly, the battery charger in accordance with the present invention utilizes fewer active components than known battery chargers and is thus much less be expensive to manufacture.
