Abstract

PURPOSE:To save energy needed for maintenance of the temperature of a battery by surrounding the battery with heat insulators and a heat medium so as to constitute a regenerator, and maintaining the tempersture of the battery by the combinational use of a heater, a cooling pump and solar energy. CONSTITUTION:A heater 2 is provided around a battery 1 which works at high temperature, and heat insulators 3 and 5 and a space 4 which accomodates a heat medium are provided around the heater 2 so as to constitute a regenertor (A). When the temperature of the battery 1 is low, the heater 2 is actuated through a sensor 12 and a control board 13, the heat medium warmed with a solar energy collector 6 is circulated, and electricity is fed through an inverter 14 into a load 16. When the temperature of the battery 1 is high, the heat medium is circulated through a cooling pipe 9 provided around the battery 1 by operating a cooling pump 8 so as to maintain the temperature of the battery 1 properly. As a result, the heat insulation and cooling can be carried out quite efficiently by enabling both the utilization of solar energy and recovery of radiated heat.

Various types of high-efficiency batteries with high energy density have been proposed and proposed (for example, lithium batteries), and their range of application is extremely wide. By the way, many of these types of high-efficiency batteries have an operating temperature of 100°C or higher, and when using them, a heat insulator is required, consuming a lot of energy to maintain the battery temperature, and increasing the temperature. There is a drawback that when cooling after the temperature reaches 90 degrees, the heat taken away is simply thrown away without any use, and is not utilized for any purpose.

へ電力が供給されるようになっている。The operation will be explained below. If the temperature of the battery 1 is lower than the predetermined operating temperature, the control panel B is activated by the detection signal of the temperature sensor, and the contact Mat" is turned ON.
AC voltage is applied to the L heater 2 to heat the battery 1. This heating continues until the temperature of the battery 1 reaches the appropriate temperature, and when the temperature reaches the predetermined temperature, the contacts M, Fi, 0F
F-jru. At this time, the temperature inside the heat storage tank A is considerably raised due to the circulation of the energy medium 4 that has been amended by the solar heat collector 6, so the energy required for heating the heater is small, and the energy is saved accordingly. You can save money. After that, the battery 1 is moderately cooled through 3 tons of heat insulating material to suppress the temperature rise associated with charging and discharging operations, but the heat is transferred to the heat medium 4 in the heat storage tank of the battery 1, where the heat is dissipated. Since it can be recovered, there is no waste heat loss, further increasing efficiency. Also, contact pigeon-hlb
When the output voltage of the battery 1 is normal, M is ON and %M is OFF and the power of the battery 1 is converted to AC power by the inverter 14 and the indoor load 16 is driven in conjunction with n. When the output voltage decreases due to overdischarge of the patch 91, the Fi contacts M, , M,
is reversed, and the indoor load 16 is
Electricity is now being supplied to.

In other words, the optimal heat retention performance and cooling performance are determined based on the temperature of 1 ton of battery, the surrounding heat insulating material, the battery, and the heat medium, but even then, there may be cases where insufficient cooling occurs when the charge/discharge amount changes greatly. According to this device, a cooling pump 8 is provided in the heat storage tank, and a cooling pump 1 is provided around the battery l.
Since the heat medium 4Yt in the heat storage tank 9 is circulated, the battery l' can be cooled to an appropriate temperature.

An AC power source 15 is connected through a contact M, which opens and closes according to the operation of the battery 1. However, when the temperature of the battery 1 exceeds a predetermined temperature, the contact M turns ON.
The L cooling pump 8 operates to perform cooling. In this case as well, the heat removed by cooling is transferred to the heat medium 4 in the heat storage tank, so heat recovery is possible and there is no waste heat loss. Since it is the same as the above, theory v4 will be omitted to avoid weight 1.

ある。As described above, in the battery heat preservation and cooling method of the present invention, in order to heat and cool a battery that operates at high temperatures, the battery is surrounded by a heat insulating material, and the surrounding area is heat insulated via a heat medium. A heat storage tank is formed by surrounding the heat medium with a heat storage tank, and the heat medium is circulated between the heat storage tank and the solar heat collector, and a heater pipe installed near the (5) tubes is appropriately controlled to maintain the appropriate temperature. Therefore, solar heat can be utilized to maintain the temperature of the battery with less energy consumption, and the heat dissipated by cooling can be recovered, so there is no waste heat loss, making it extremely efficient for battery heat retention and storage. This has the effect of providing a cooling method.
