This present invention provides a packing scheme for battery cells, known as FSTP (First Serial Then Parallel). That is, when building a battery pack, first the battery cells are connected in serial to reach the required voltage, then the resulted battery strings are connected in parallel to reach the required capacity. A final battery pack is thus completed. This scheme possesses the following advantages: (1) Safety of the pack against catching fire is greatly improved by an order of magnitude, since each of every cell in the pack has been monitored; (2) Total cost is contained within acceptable level; (3) Cell strings can be easily switched out of the pack, resulting in removing faulted cells instantly without significantly impacting operation. And the costly active battery balancing becomes unnecessary.

An electrical storage system includes a main battery, an auxiliary battery, a bidirectional DC-DC converter and a controller. The bidirectional DC-DC converter is provided between the auxiliary battery and a power supply path from the main battery to a driving motor. The bidirectional DC-DC converter steps down an output voltage from the power supply path to the auxiliary battery, and steps up an output voltage from the auxiliary battery to the power supply path. The controller controls charging and discharging of the auxiliary battery. The controller, when an allowable output power of the main battery decreases and an electric power becomes insufficient for a required vehicle output, supplies an electric power to the power supply path by discharging the auxiliary battery by using the bidirectional DC-DC converter. The controller, when an allowable input power of the main battery decreases and a regenerated electric power generated by the driving motor is not entirely charged into the main battery, charges part of the regenerated electric power into the auxiliary battery by using the bidirectional DC-DC converter.

A motor driven appliance comprises a battery, a motor, at least one switch, a control unit, an abnormality detection unit, a determination unit, and a processing unit. The at least one switch comprises an operation switch. The control unit controls driving of the motor by controlling power supply from the battery to the motor when the operation switch is turned on. The abnormality detection unit detects abnormality of the appliance. The determination unit determines whether the detected abnormality is a first type abnormality that can be cleared when the operation switch is switched from on to off, or is a second type abnormality that cannot be cleared even if the operation switch is merely switched from on to off. The processing unit is configured to perform a specific process when it is determined that the detected abnormality is the second type abnormality.

An external charger for an implantable medical device (IMD) includes a multi-layer shield to direct the magnetic field generated by its charging coil towards the IMD. Each of the shield's multiple layers includes a ferromagnetic material that increases the permeance of the magnetic field's flux paths. The layers decrease in magnetic saturation point with increasing distance from the external charger's charging coil. That is, the layer closest to the charging coil has a higher saturation point than the next layer further from the charging coil, and so on. Layers that are positioned closer to the charging coil shield layers that are further from the charging coil, which generally have higher magnetic permeabilities, such that the magnetic intensity does not exceed any layer's saturation point. In this way, the multi-layer shield provides a beneficial balance between permeability and saturation, which can limit the required dimensions of the shield.

The battery pack includes a battery cell for supplying electric power to an external device connected thereto, a temperature sensor for sensing a temperature of a place on which the temperature sensor is arranged, a switch member for making and breaking an electric path between the external device and the battery cell; and a controller configured to control the switch member to turn on and off according to the temperature sensed by the temperature sense. The temperature sensor is arranged on a position between the battery cell and the switch member so as to be affected by the temperatures of both of the battery cell and the switch member.
