In the battery, several similar plates are properly spaced and welded, or lead-burned, to a strap. This forms a plate group. Plates of two types are used, one for the positive plate group, the other for the negative plate group. A positive plate group is nested with a negative plate group. Separators are placed between the plates to form an element (Fig. 24-3). The separators hold

and water on the lead dioxide plate. ! As the battery discharges, both plates build up PbSO4 (lead sulfate), and water builds up in the acid. The characteristic voltage is about 2 volts per cell, so by combining six cells you get a 12-volt battery. A lead-acid battery has a nice feature -- the reaction is completely reversible. If you apply
The operating process involves the liquid (e.g., silicone oil) heated by the heater flows between the cells by employing the pump, facilitating the transfer of heat from the liquid to the battery. The inlet temperature, heating time, and external ambient temperature of the battery heating system all have an effect on the heat balance performance.
Plates are attached to the surface of battery cells or modules. They are engineered with the largest possible surface area to maximize contact with the battery and facilitate heat transfer away from the cells. The coolant fluid flowing inside the plate also enhances heat transfer.
When heat is generated within the battery during operation, it naturally flows towards areas of lower temperature. The cooling plate acts as a conduit drawing heat away from the cells and dispersing it into the surrounding environment or to other thermal management system components, such as heat exchangers or coolant loops.
The inlet temperature, heating time, and external ambient temperature of the battery heating system all have an effect on the heat balance performance. The temperature uniformity is poor due to the narrow space, and the temperature of the water heating the battery is also decreased with the increase of the distance the water flows through .
