Emissions caused by excess hydrogen combustion and explosion has become a must attach great importance to solve the problems with

Because non-polluting electric cars, energy efficiency advantages to become the 21st century's most promising new type of environmentally friendly cars. Its power source, most lead-acid batteries, hydrogen - nickel batteries, cadmium - nickel batteries and so on. Some data indicate that these batteries in electric vehicles usage accounted for 78% to 95%. Since the widespread use of these batteries, the car is moving and the charging and discharging process, especially overcharge and  air circuit breaker occurs, the emissions caused by excess hydrogen combustion and explosion has become a must attach great importance to and solve the problem. The concentration of hydrogen explosions have certain limits, introduce real-time monitoring system, according to the National Motor Vehicle Safety Standard GB / T1 8384.1-2001 (hereinafter referred to as the standard) in the case of  power transformers  hydrogen concentration at the request of the concentration of hydrogen in real time detection and alarm. System Development  Air circuit breaker  in the charge to the battery, should be measured within the area specified by the manufacturer of the concentration of hydrogen in the exhaust gas; when the vehicle is traveling inside the hydrogen concentration measurement. According to this requirement, the need for real-time monitoring system within a predetermined area (charge) and the vehicle (traveling within) the hydrogen concentration detected.
