摘要:
A workpiece, in which a lead is laid on top of a three-dimensional porous metal body, is placed between an ultrasonic horn and an anvil with a lead portion facing the ultrasonic horn. A support is raised so that the lead portion of the workpiece is pressed between the ultrasonic horn and the anvil. While being rotated around a central shaft with a motor, the ultrasonic horn vibrates at a frequency of 20 kHz in the shaft direction. Thus, the workpiece is advanced continuously, so that the lead is bonded ultrasonically to the three-dimensional porous metal body (i.e., metal-to-metal bonding is established). It is possible to provide a battery electrode that can be produced continuously at a lower running cost, reduce the faulty welding with a current collecting plate, and prevent short-circuits.

A power source has a battery pack housing a plurality of interconnected battery modules wherein a plurality of single cells are connected serially. A blower is provided which forces air through the battery pack to maintain the battery modules at a correct temperature. A controller controls the blower in accordance with data provided by sensors which detect voltage, current and temperature. The controller outputs the data and a state of charge. A charging/discharging current circuit includes a relay for interrupting charging and discharging of the battery modules in the event of failure and also includes a rush current prevention resistor and a current sensor. The controller permits the power source to be maintained in a correct operating condition wherein neither overcharging nor undercharging occurs.
摘要:
An air-conditioner ECU sets the maximum flowrate or a set flowrate which is less than the maximum flowrate as a required flowrate Vr based on outside air temperature when a DEF mode is selected, and requires that coolant be circulated (steps 100 to 110). Also, when the coolant temperature Tw during heating is between a set temperature TS3 and a set temperature TS1, circulation of coolant at the minimum flowrate is required (steps 134, 130, 132). When a blower fan is stopped when the coolant temperature is equal to or less than the set temperature TS3 and a fresh air mode is selected, the circulation of coolant at the minimum flowrate is required when the vehicle speed Sv is above a set vehicle speed (steps 134 to 146). Cool air is prevented from being blown out of an air outlet and heating of the coolant is promoted by suppressing the speed of an electric pump while maintaining the ability to prevent fogging.
摘要:
A fluid-cooled battery pack system can maintain the variation in battery temperature in a battery pack within the permissible temperature range even when the variation in the gaps between battery modules is considered. A plurality of battery modules are each provided with a plurality of convex portions and concave portions on the sides thereof, where the connections to other battery modules are made. When the battery modules are connected by bringing the opposite convex portions into contact with each other, coolant flow paths, through which a coolant flows, are formed. The target width of the coolant flow paths is set so that the variation in temperature relative to the target temperature of each battery module is maintained within a predetermined range when the coolant flows through the coolant flow paths; the variation in temperature is caused by a fabrication tolerance relative to the target width of the coolant flow paths between the battery modules.

摘要:
A device and method of input/output control capable of exhibiting the battery performance by nature by rapidly raising the temperature of the secondary battery by the regeneration at a low temperature. A temperature rise controller controls the temperature rise of the battery pack based on the battery temperature, thereby determining a central value of the state-of-charge control in the range of the state of charge. A battery input/output controller voluntarily controls the state of charge based on the central value of the state-of-charge control from the temperature rise controller and the state of charge at the point of time from the state-of-charge operator, and controls charge and discharge based on the charge and discharge request from the outside to the battery pack.
